searx -- A privacy-respecting, hackable metasearch engine

Searx (/sɜːrks/) is a free metasearch engine, available under the GNU Affero General Public License version 3, with the aim of protecting the privacy of its users. Across all categories, Searx can fetch and combine search results from more than 80 different engines. This includes major commercial search engines like Bing, Google, Qwant, DuckDuckGo and Reddit, as well as site-specific searches such as Wikipedia and Archive.is. Searx is a self hosted web application, meaning that every user can run it for themselves and others - and add or remove any features they want. Meanwhile, numerous publicly accessible instances are hosted by volunteer organizations and individuals alike. The project will consolidate the many suggestions and feature requests from users and operators into the first full-blown release (1.0) for Searx, as well as spend the necessary engineering effort in making the technology ready for even wider deployment.

searx -- Federating self-hosted search hubs

Searx is a popular meta-search engine, with the aim of protecting the privacy of its users. In the typical use case, few users trust one instance. However, a third-party services can easily fingerprint the users using the IP address of the searx instance and the user's queries. The project aims to create a searx federation to solve this issue. First, a protocol needs to be defined to allow the instances to discover themselves. Then, each instance will be able to proxy the HTTPS requests through other instances, so the user only has to trust one instance. Also, each instance will spread the requests to other instance according to their response time, and make that IP addresses are evenly used, or at least in the best possible way. To ensure the latter, the statistics page will be enhanced and available through an API that other instances will use. The federation will make sure that bots can't abuse this pool of IP address.

Practical Decentralised Search and Discovery -- Search and discovery inside mesh/adhoc networks

Internet search and service discovery are invaluable services, but are reliant on an oligopoly of centralised services and service providers, such as the internet search and advertising companies. One problem with this situation, is that global internet connectivity is required to use these services, precisely because of their centralised nature. For remote and vulnerable communities stable, affordable and uncensored internet connectivity may simply not be available. Prior work with mesh technology clearly shows the value of connecting local communities, so that they can call and message one another, even in the absence of connectivity to the outside world. The project will implement a system that allows such isolated networks to also provide search and advertising capabilities, making it easier to find local services, and ensuring that local enterprises can promote their services to members of their communities, without requiring the loss of capital from their communities in the form of advertising costs. The project will then trial this system with a number of pilot communities, in order to learn how to make such a system best serve its purpose.

The Open Green Web -- Ethical meta-search filter on green hosted websites

The world wide web has become a mainstay of our modern society, but it is also responsible for a significant use of natural resources. Over the last ten years, The Green Web Foundation (TGWF) has developed a global database of around 1000 hosters in 62 countries that deliver green hosting to their customers, to help speed a transition away from a fossil fuel powered web. This has resulted in roughly 1.5 billion lookups since 2011 - through its browser based plugins, manual checks on the TGWF website and its API, provided by an open source platform. But what if you want to take things one step further? This project will create the world's first search engine with ethical filtering, that will exclusively show green hosted results. In addition to giving a new choice of search engine to environmentally conscious web users, all the code and data will be open sourced. This creates a reference implementation for wider adoption across industry of search providers, increasing demand and visibility around how we power the web. The project build upon the open source search engine Searx, and will collaborate with the developers of that search tool to make "green" search an optional feature for all installs of Searx.

Private Searx -- Add private resources to the open source Searx metasearch engine

Searx is a popular meta-search engine letting people query third party services to retrieve results without giving away personal data. However, there are other sources of information stored privately, either on the computers of users themselves or on other machines in the network that are not publically accessible. To share it with others, one could upload the data to a third party hosting service. However, there are many cases in which it is unacceptable to do so, because of privacy reasons (including GPPR) or in case of sensitive or classified information. This issue can be avoided by storing and indexing data on a local server. By adding offline and private engines to searx, users can search not only on the internet, but on their local network from the same user interface. Data can be conveniently available to anyone without giving it away to untrusted services. The new offline engines would let users search in local file system, open source indexers and data bases all from the UI of searx.

Re-isearch -- Vectorise text with a flexible unit of retrieval

*Project re-isearch: a novel multimodal search and retrieval engine using mathematical models and algorithms different from the all-too-common inverted index (popularized by Salton in the 1960s). The design allows it to have no limits on the frequency of words, term length, number of fields or complexity of structured data and support even overlap--- where fields or structures cross other's boundaries (common examples are quotes, line/sentences, biblical verse, annotations). Its model enables a completely flexible unit of retrieval and modes of search.

Initial project outcome: a freely available and completely open-source (and multiplatform) C++ library, bindings for other languages (such as Python) and some reference sample code using the library in some of these languages.

SEARXR -- Virtual reality for web search

SearXR brings a beautiful, privacy-respecting search to 2D and 3D devices. Why? Because searching on alternative devices (VR headsets, conference-presentation) is not always easy nor private. SearXR aims to provide alternative search interfaces which are more appropriate for VR, AR and big screens. SearXR aims to progressively enhance these search experiences: better screen-layout, privacy, and WebXR compatibility. All features are based on user preferences and available hardware. Built upon SearX and W3C's WebXR technology, it will enable everybody to search, or add XR-features to their SearX instance. Whether it be state of the art headsets, or a 65” screen: pointing the browser to an SearXR-instance will immediately launch a wonderful, privacy-respecting search experience.

YaCy Grid SaaS -- YaCy Grid SaaS

YaCy Grid Search-as-a-Service creates document crawling indexing functionality for everyone. Users of this new platform will be able to create their custom search portal by defining their own document corpus. Such a service is an advantage as a privacy or branding tool, but also allows scientific research and annotation of semantic content. User-group specific domain knowledge can be organized for custom applications such as fueling artificial intelligence analysis. This should be a benefit i.e. for private persons, journalists, scientists and large groups of people in communities like universities and companies. Instances of the portal should be able to self-support themselves financially: there is turn-key infrastructure to handle payments for crawling/indexing amounts as a subscription on a periodical basis while search requests are free for everyone. The portal will consist of free software, and users can download the portal software itself together with the acquired search index data - so everyone can start running a portal for themselves whenever they want.

ipfs-search.com -- Search engine for the Interplanetary File System

ipfs-search.com is a Free and Open Source (FOSS) search engine for directories, documents, videos, music on the Interplanetary Filesystem (IPFS), supporting the creation of a decentralized web where privacy is possible, censorship is difficult, and the internet can remain open to all.

Nominatim -- Multi-lingual support in address search

Nominatim is an open-source geographic search engine (geocoder). It makes use of the data from OpenStreetMap to built up a database and API that allows to search for any place on earth and lookup addresses for any given geographic location. It is used as the main search engine on the OpenStreetMap website where it serves millions of requests per day but it can also be installed locally. You can easily set it up for a small country on your laptop. Nominatim has always aimed to be usable world-wide for any place in any language. To that end it has used generic, language-agnostic algorithms that assume a uniform data model. This has served us especially well while the OpenStreetMap database was in its early stages of development and changing fast. Now that it has matured, it is time to further improve the search experience by taking into account the particularities of different languages and the different practises when it comes to geographic addressing. We aim to restructure the part of the software that parses the place names and search queries to make it more configurable and make it easier to take into account languages and regional peculiarities.

Solid-Search -- Queries in a pod

Solid-Search aims to provide an open source module that adds full-text search functionality to Solid pods. Solid is an emergent specification initiated by the inventor of the World Wide Web, sir Tim Berners-Lee. Solid aims to decentralize the web by decoupling applications from databases by introducing Solid Pods (personal online datastores that are in full control of the data owner). Having a way to search through your personal data on your Solid Pod is a must-have for the project to become truly successful. However, this requires technology that does not exist yet: a full-text search interface that works with schema-less RDF data. In order to maximize adoption and retain a modular, open approach, we will standardize the way in which data changes are described. By doing so, it will be relatively easy to introduce new search / query systems (such as search by location). The project will will create the open source search back-end, improve linked data synchronisation specs, link the module to two solid implementations, create a front-end for end-users, and write a tutorial for adding data sources.

Tantum Search -- Context-enhanced search driven by schema.org

Tantum Search’s goal is to present information in a fair and transparent context for the users. The platform lets users make an inventory of any information using schema.org schemas (like video, audio, paintings, ebooks, events, goods, services) and allows users to search through these entries on three axes: word, contextual and geo reference resolution. Providers of information can easily and without great effort add their information to the platform and make it available online – the platform automatically creates an interactive page which will be search engine optimized and users get free and unbiased access to search for goods and services. The ranking focuses on the search query and less on link popularity. Thus, ‘internet giants’ are not necessarily listed at the top due to their popularity and in addition, the ranking algorithm will be transparently released as open source so the community can optimize it.

Minedive -- P2P search over webRTC

The minedive project is building several components: first, minedive is a browser extension aiming to allow users to search the web while preserving their anonymity and privacy. The second is an open source reference implementation of its rendez-vous server. minedive instances connect each-other (via WebRTC data channels) forming a two layered P2P network. The lower layer (L1) provides routing, the upper layer (L2) provides anonymous and encrypted communication among peers acting as a MIX network. This architecture guarantees that peers which know your IP address (L1) do not know search data for (L2) and vice-versa. A central (websocket) rendez-vous server is needed to find and connect with L1 peers, and to exchange keys with L2 peers, but no search goes through it. We are running a default server which can be overridden by users who want to run their own (using our reference implementation or a custom one). Users can also set the extension to pick peers from a given community (identified by an opaque tag). Currently all requests are satisfied by letting L2 peers return results from the 1st page of mainstream search engines (as they see it, in an attempt to escape the search bubble). While this will stay as a fallback, we plan to implement web crawling on peers, doing keyword extraction from URLs in local bookmarks and history and ranking with open algorithms, being transparent with users about which techniques are used and open to suggestions.

MeiliSearch -- Modern and responsive search

Advanced content search for apps and websites has become an increasingly protected craft. When owners of big content repositories need search at scale, they have to choose between hiring expensive search specialists or outsourcing search in its entirety. Search doesn’t need to be this complicated. It should be simple enough to be self-hosted with the developers you already have, and it should be understandable & open enough that you can resort to a managed cloud without fear of lock-in.

MeiliSearch is blazing fast and very light on resources. It packs advanced search capabilities like search-as-you-type, relevancy , typo-tolerance, synonyms and filters, all set up and configured in minutes. Our primary path to widespread adoption is integration with other developer ecosystems. Every new language, framework, platform or application that’s supported brings in a new audience of developers that wouldn’t otherwise know we even exist.

Explain -- Deep search on open educational resources

The Explain project aims to bring open educational resources to the masses. Many disparate locations of learning material exist, but as of yet there isn’t a single place which combines these resources to make them easily discoverable for learners. Using a broad array of deep content metadata extraction techniques developed in conjunction with the Delft University of Technology, the Explain search engine indexes content from a wide variety of sources. With this search engine, learners can then discover the learning material they need through a fine-grained topic search or through uploading their own content (eg. exams, rubrics, excerpts) for which learners require additional educational resources. The project focuses on usability and discoverability of resources.

Blink RELOAD -- Secure P2P real-time communications with RELOAD

REsource LOcation And Discovery specification (RELOAD) is a standard produced by the IETF standard to (as the name indicates) describe how people can search within a local network to discover other people and devices they can then exchange video and voice calls with, send messages etc. Why make every discovery depend on the availability of a global DNS system, if you are actually near each other...

Blink is a mature open source real-time communication application that can be used on different operating systems, based on the IETF SIP standard. It offers audio, video, instant messaging and desktop sharing. Blink RELOAD aims to implement RELOAD (RFC 7904) , which describes a peer-to-peer network that allows participants to discover each other and to communicate using the IETF SIP protocol. This offers an alternative discovery mechanism, one that does not rely on server infrastructure, in order to allow participants to connect with each other and communicate. In addition, the RELOAD specification describes means by which participants can store, publish and share information, in a way that is secure and fully under the control of the user, without a third party controlling the sharing process or the information being shared.

AEAP -- Automated e-mail address porting to a new provider

There is no search for email addresses, like there was in the days long gone of the phone book. Once an old contact disappears (e.g. moves jobs, changes provider), even hough you may have exchanged many emails with that person you can not discover which new email address(es) go(es) with that old contact.

The Automated E-mail Address Porting project (AEAP) wants to allows you to find the new email addresses of these existing email contacts. The project will research and develop the porting of an e-mail address to a new provider. We will implement, document, user-test and release a porting mechanism for Delta Chat, a leading end-to-end encryption mail client. Users can decide they want to use a new provider by entering credentials for a new e-mail address. The outcome of the AEAP project will be Delta Chat Desktop, Android and iOS releases to all app stores, providing seamless porting of e-mail addresses. Changing an e-mail provider will not depend on the consent of the existing one. GMail and various other "free e-mail" provider lock-in strategies will be weakened, also through the e2e-encryption that our AEAP effort spearheads.

Castopod -- Podcasting in the fediverse

Castopod is an open-source podcast hosting solution for everyone, that can connect to the Fediverse through the W3C ActivityPub standard (Pixelfed, Mastodon, Pleroma…). Castopod is user friendly, and allows for easy discovery everywhere. Whether you are a beginner, an amateur or a professional, you will get everything you need: you can create, upload, publish, manage server subscriptions (WebSub embedded server). You can allow users to listen to your podcast directly, but just as easily connect to commercial directories (Apple, Google, Spotify…).

Take back control: interact with your audience on your platform (like, share, comment), the social network IS the podcast. In addition to supporting W3C ActivityPub, you can also export to proprietary social networks (Twitter, Instagram, Youtube, Facebook). Castopod is easily hosted on any PHP/MySQL server: unzip it and you and other podcasters are ready to broadcast professionally.

Record Federation for Corteza Clouds -- Data federation over ActivityPub

Corteza is a low code platform for building cloud-based web applications. This is typically for private, records-based management purposes (e.g. case management, insurance claims processing, public sector management applications, CRM, ERP), but the uses can also be public if required. It has a modular architecture and its data later, presentation layer and automation layer can each be treated individually. Corteza Record Federation makes innovative use of the ActivityPub standard to describe how content from the Corteza data layer can be broadcast across large federations of Corteza clouds. All data types, simple or compound, entire records and entire data models are supported.

Whether it be energy, finance, health, education or smart cities, many industries need to share complex data in real-time or near real-time, while preserving the digital sovereignty of a large number of disparate actors, protecting the privacy of user data and acknowledging the law of whichever territories in which they find themselves operating. Corteza Record Federation allows for the creation of private networks of decentralised “mini-clouds”, all self-hosted and controlled by their owners, where this data exchange can happen as efficiently and more effectively than on any single centralised cloud.

Creative Passport -- Allow creative artists to gain visibility and build reputation on the web

The Creative Passport is a personalised digital ID for Music Makers, allowing them to update, manage and control all information about themselves and their works from one place.

Artists' Information online is often in different places and incorrect: biographies, photos, skills, roles, inspirations, teams and contacts, identifiers, digital accounts, concerts, credits, collaborators. Thanks to the Creative Passport Music Makers can push updated profile information into other integrated music services, at the touch of a button. The goal is to become a unique login solution, decreasing admin work on ID verification for services accepting The Creative Passport Credentials. As The Creative Passport will also offer a way for its user to exchange secure messages and to p2p verify each others, we intend to Create a social graph with other passport holders using ActivityPub activitystream actions.

The social graph is a key element for the Creative Passport, as it allows for a grass roots validation of holders as active with the music space without having to rely on the larger players of the music industry. It needs to be a useful social space for the participants, to allow for new services to be built on connections and abilities to share messages with a graph without compromising the trust inherent in having the graph represented in a digital space, so each Passport Holder holds their own graph.

DeltaBot -- Social discovery over mail-based chat

Why make humans be the only ones to search new content that is relevant to you, if bots can be made to do the same on your behalf? The DeltaBot project will research and develop decentralized, e2e-encrypting and socially trustworthy bots for Delta Chat (https://delta.chat). Bots will bridge with messaging platforms like IRC and Matrix, offer media archiving for its users and provide ActivityPub and RSS/Atom integration to allow users to discover new content. Our project is not only to provide well tested and documented Chat Bots in Python but also help others to write and deploy their own custom bots. Bots will perform e2e-encryption by default and we'll explore seamless ways to resist active MITM attacks.

Discourse ActivityPub -- Connecting internet discussions with ActivityPub

Discourse is a modern open source discussion platform. In some ways it can work similar to email but it much better suited to large scale group discussions that in turn become searchable (i.e. indexable) items of knowledge on the world wide web (given that the forum is publicly viewable). We are building a two-way mirror for Discourse topics, compatible with the ActivityPub standard. The first iteration of this will be "Live Topic Links": When a topic is created on Forum A by pasting a URL to a topic on another Discourse instance (Forum B), the user is prompted "would you like to sync replies between this forum and the forum you're linking to?" If the user clicks "yes," replies to the mirror topic on Forum B would be synced back to the topic on Forum A, and vice versa (if Forum B has "whitelisted"rum A).

EDeA -- A forge suitable for open hardware development

The short version: EDeA is a novel approach to allow exploration of and improve discovery within the open hardware ecosystem - in order to help make open hardware designs and components discoverable and reusable.

At this moment in time, pretty much everything surrounding open hardware development is manual. Beyond just typing something into a generic search engine there isn't really suitable tooling available to search across what already exists. Accessible and usable distributions, collaboration tools and version control are what drove the free and open source software revolution, now open hardware needs to take the same leap forward.

Open hardware electronics projects are growing in numbers, thanks to crowdfunding, a strong developer community, and sophisticated open source electronic design automation (EDA) tools like KiCad. Between circuit schematic and printed circuit board (PCB) layout there is a logical association, but are being handled by separate programs, and therefore one can’t simply copy-paste design blocks. In 2020 it is still next to impossible to reuse proven parts of different designs without needless reimplementation. By leveraging KiCad’s pcbnew and eeschema scripting, a new way of building modular, reusable electronics opens. We are creating a catalog and community portal for discovery and development of proven circuit modules: power management, signal conditioning, data conversion, micro-controllers, etc.

FairSync -- Simplify aggregation and discovery of places and events

How can we make it possible to search across different maps and lists of events maintained by different organisations? By connecting them, of course! FairSync develops and collects best practices to synchronize maps and events and to federate messengers and identities active in the global movement for sustainability. System integrators are faced with fast evolving APIs and protocols when they try to discover and connect systems and make search more easy.

We will work on master-master replication frameworks of metadata enriched data sets and test with platform providers for sustainability affairs. One approach is the "lazy master scheme": a common update propagation strategy where changes on a primary copy are first committed at the master node, afterwards the secondary copy is updated in a separate transaction at slave nodes.

We will try to advance such immediate update propagation in this project using protocols such as ActivityPub or the InCommon API. Federation of identities will be managed with SAML or oAuth2 protocols with fairlogin as a common identity provider.

fediverse.space -- Find your way in the Fediverse

Fediverse.space is a tool for understanding decentralized social networks, and searching through them. The fediverse, or federated universe, is the set of social media servers, hosted by individuals across the globe, forming a libre and more democratic alternative to traditional social media. When displaying these servers in an intuitive visualization, clusters quickly emerge. For instance, servers with the same primary language will be close to each other. There are more subtle groupings, too: topics of discussion, types of users (serious vs. ironic), and political leanings all play a role. fediverse.space aims to be the best tool for understanding and discovering communities on this emerging social network.

ForgeFed -- Federation for software collaboration tools

When you are searching for new software to use, you will have to visit many different software forges - like Gitlab, Codeberg or Sourcehut. There isn't really a tool to search for anything across the boundaries of these different software forges.

ForgeFed aims to define a vocabulary and a protocol for decentralized communication and federation of websites used for hosting and collaboration on version control repositories, issue tracking and project management. Typical such websites are code forges such as GitLab and Gitea instances (and centralized services like github), but the idea also applies to applications like collaborative civic planning, publishing of creative writing (such as prose and poetry) and more. ForgeFed is to be designed as an extension of ActivityPub, and web apps implementing it would be joining the Fediverse. The world of repo and project hosting would switch from the centralized model of github (and the lonely disconnected websites running GitLab or Gitea etc.) into a network of federating websites, creating a global decentralized community. The project will publish a set of specifications and guides for implementing the federation protocol, and to work with existing projects and communities to refine and finalize the specifications and implement ForgeFed federation.

Funkwhale -- ActivityPub-driven audio streaming and sharing

Funkwhale is a free, decentralized and open-source audio streaming and sharing platform, built on top of the ActivityPub protocol. It enables users to create communities of interest around music and audio content in general, listen to their private music library or distribute their own productions on the network. Each Funkwhale pod, or server, can communicate with other pods to exchange audio content, metadata or for user interactions. In this project, Funkwhale will improve the publication experience for creators, release its first stable version, improve content discovery inside the platform through better sharing and search mechanisms. We will also continue research and development for Retribute, a community wealth sharing platform meant to support creators on Funkwhale or any other platform.

GNU social -- Modernizing the original FOSS Social Network

GNU social is a free social networking platform, easily self-hostable and highly accessible, that enables both private and public decentralized communications. With NLnet NGI Zero's support, the project is undergoing a change of main focus from microblogging to groups and tags. With this, GNU social will be a space for communities where users can express their passions and explore new ones. Users will be able to immerse themselves in easily filterable content relevant to their interests, and to create and join communities. It's hard to pinpoint an existing alternative service that promotes the same level of functionality in terms of tagging, filtering and connecting with people that share common interests. Especially considering the available degree of accessibility, customization and expansion via plugins.

Hubzilla -- Federated social networking environment

Hubzilla is one of the most mature stacks within the so called Fediverse, and is able to run different protocols such as ActivitPub, Diaspora and Zot. Hubzilla provides powerful tools for communities and individuals to help organise themselves, while providing a possibility to interact with each other. It is a decentralised identity, communications and permissions framework built, using common webserver technology. The software features many useful apps to enable discussions, event organisation, file sharing etc. with built-in internet-wide access control. With Hubzilla you don't have an account on a server, you own an identity that you can take with you across the network.

With the help of the NGI Zero grant, the new version of the zot protocol (zot6) will be implemented as the primary communication protocol and the UX/UI will be improved to lower the entry barrier for less experienced computer users. And of course you can easily search your Hubzilla server for topics, users, fora and tags.

Sonar: a modular peer-to-peer search engine for the next-generation web -- Modular peer-to-peer search engine

Sonar is a project to research and build a toolkit for decentralized search. Currently, most open-source search engines are designed to work on centralized infrastructure. This proves to be problematic when working within a decentralized environment. Sonar will try to solve some of these problems by making a search engine share its indexes incrementally over a P2P network. Thereby, Sonar will provide a base layer for the integration of full-text search into peer to peer/decentralized applications. Initially, Sonar will focus on integration with a peer-to-peer network (Dat) to expose search indexes securely in a decentralized structure. Sonar will provide a library that allows to create, share, and query search indexes. An user interface and content ingestion pipeline will be provided through integration with the peer to peer archiving tool Archipel.

IN COMMON -- Public platform to map and act together for the Commons

IN COMMON emerged as a transnational European collective from a network of non-profit actors to identify, promote, and defend the Commons. We decided to start a common pool for Information Technologies with the aim to create, maintain, and share with the public geo-localized data that belong to our constituents and to articulate citizen movements around a free, public and common platform to map and act together for the Commons. IN COMMON forms a cooperative data library that provides collective maintenance to ensure data is always accurate.

Practical Tools to Build the Context Web -- Declarative setup of P2P collaboration

In a nutshell, the Perspectives project makes collaboration behaviour reusable, and workflows searchable. It provides the conceptual building blocks for co-operation, laying the groundwork for a federated, fully distributed infrastructure that supports endless varieties of co-operation and reuse. The declarative Perspectives Language allows a model to translate instantly in an application that supports multiple users to contribute to a shared process, each with her own unique perspective.

The project will extend the existing Alpha version of the reference implementation into a solid Beta, with useful models/apps, aspiring to community adoption to further the growth of applications for citizen end users. Furthermore, necessary services such as a model repository will be provided. This will bring Perspectives out of the lab, and into the field. For users, it will provide support in well-known IDE's for the modelling language, providing syntax colouring, go-to definition and autocomplete.

Real life is an endless affair of interlocking activities. Likewise, Perspectives models of services can overlap and build on common concepts, thus forming a federated conceptual space that allows users to move from one service to another as the need arises in a most natural way. Such an infrastructure functions as a map, promoting discovery, decreasing dependency on explicit search. However, rather than being an on-line information source to be searched, such the traditional Yellow Pages, Perspectives models allow their users (individuals and organisations alike) to interact and deal with each other on-line. Supply-demand matching in specific domains (e.g. local transport) integrates readily with such an infrastructure. Other patterns of integrating search with co-operation support form a promising area for further research.

Inventaire -- Wikidata-based social sharing of reading experiences

The Inventaire Project is an effort to move forward on the front of accessing information on resources using libre software powered by open knowledge. This ideal is being materialized in the form of inventaire.io, a libre book sharing webapp, inviting everyone to make the inventory of their physical books, declare what they want to do with it (giving, sharing, selling), as well as who should be able to see it (shared publicly through e.g. ActivityPub, or only visible by your friends and groups).

To power those inventories with structured bibliographic data, inventaire.io is also playing the role of a Wikidata-federated open and contributive bibliographic database, extending wikidata.org data with Wikidata-compatible entities (CC0, shared data schema) tailored to our needs, but ready to be pushed to Wikidata when the data contributor deems it appropriate. This linked open data architecture allows users to build their inventories on a huge open knowledge graph, that we believe will, in time, offer exceptional discovery capabilities. Now that this first base of inventories and contributive bibliographic data reaches a certain level of maturity, we want to start moving forward on the next challenges: introduce curation and recommendation mechanisms, improve search tools, offer finer privacy settings, and move forward on decentralization.

Kazarma -- Bridge ActivityPub and Matrix realms

Matrix-Appservice-CommonsPub is a bridge between two decentralized protocols: Matrix and ActivityPub. The development includes polishing CommonsPub, an Elixir generic ActivityPub implementation, and creating an Elixir library to build Matrix bridges. We will first focus on private messages between Matrix users and users of an ActivityPub-enabled platform, like PeerTube or Funkwhale, then explore the possibilities of synchronizing ActivityPub feeds (e.g. "toots" feeds) in Matrix. The bridge comes as an easy-to-deploy, secure and scalable solution.

Keyoxide -- Self-hostable identity proofs with bidirectional linking verification

How do you discover which other online accounts across different services and service providers actually belong to the same person? Keyoxide is a secure, privacy-friendly and decentralized platform to manage online identities, uncompromisingly driven by what the user herself wants to share.

Keyoxide is a new type of service to allow proving linked account ownership on a variety of platforms. Keyoxide levers existing and battle-tested cryptographic primitives. The goal is to give users more control over their online presence, independent from dominant internet actors - without in fact having to depend on any centralised services or third parties. The project will improve the usability of the current Keyoxide, and its emerging underlying technology (Decentralized OpenPGP Identity Proofs). More service providers will be added and additional tools to provide proofs will be developed, to create a smooth and easy onboarding process for less tech-savvy people.

Lemmy -- ActivityPub for link aggregation

Lemmy is an open-source, easily self-hostable link aggregator that you can use to share and discover interesting new ideas - and discuss them with the world. Its designed to work in the Fediverse, and communicate natively with other ActivityPub services, such as Mastodon, Funkwhale and Peertube.

Lemmy aim to create a decentralized alternative to widely used proprietary services like Reddit. For a link aggregator, this means a user registered on one server can subscribe to communities on any other server, and have discussions with users registered elsewhere. The front page of popular link aggregators is where many people get their daily news, so Lemmy has the potential to help alter the social media landscape.

openEngiadina -- Platform for creating, publishing and using open local knowledge

OpenEngiadina is developing a platform for open local knowledge - a mashup between a semantic knowledge base (like Wikipedia) and a social network using the ActivityPub protocol. openEngiadina is being developed with small municipalities and local organizations in mind, and wants to explore the intersection of Linked Data and social networks - a 'semantic social network'.

openEngiadina started off as a platform for creating, publishing and using open local knowledge. The structured data allows for semantic queries and intelligent discovery of information. The ActivityPub protocol enables decentralized creation and federation of such structured data, so that local knowledge can be created by indepent actors in a certain area (e.g. a music association publishes concert location and timing). The project aims to develop a backend allowing such a platform, research ideas into user interfaces and strengthen the ties between the Linked Data and decentralized social networking communities.

Peertube-Desktop -- Enjoy and share federated videos

PeerTube Desktop is a client for PeerTube that will allow for searching and discovering new and interesting video's online with more privacy. PeerTube is a federated video hosting service based on the W3C ActivityPub standard. By using WebTorrent - a version of BitTorrent that runs in the browser - users help serve videos to other users. PeerTube Desktop is a desktop client for PeerTube, but will work on GNU/Linux-based phones (like the Librem 5 or Pinephone) as well.

We want the experience of watching PeerTube videos and using PeerTube in general to be better, by making a native application that will become the best and most efficient way to hook into the federation of interconnected video hosting services. It will have improved search, and will allow people to continue sharing watched videos with other PeerTube users for longer periods of time, instead of discarding the video when done watching. It will also help bridge PeerTube's gap between the - now separated - BitTorrent and WebTorrent networks by speaking both of those protocols.

Extending PeerTube -- Adding advanced search capabailities to PeerTube

This project aims to extend PeerTube to support the availability, accessibility, and discoverability of large-scale public media collections on the next generation internet. Although PeerTube is technically capable to support the distribution of large public media collections, the platform currently lacks practical examples and extensive documentation to achieve this in a timely and cost-efficient way. This project will function as a proof-of-concept that will showcase several compelling improvements to the PeerTube software by [1] developing and demonstrating the means needed for this end by migrating a large corpus of open video content, [2] implementing trustworthy open licensing metadata standards for video publication through the PeerTube platform, [3] and emphasizing the importance of accompanying subtitle files by recommending ways to generate them.

PixelDroid -- Share and browse photos in the fediverse with a mobile app

PixelDroid is an Android client for Pixelfed, the federated image sharing platform based on W3C ActivityPub. Our goal is to bring the Pixelfed platform to Android and provide a mobile user experience that excites. We aim to provide feature-parity with the Pixelfed web client as well as add additional features - like image and video editing, capturing and uploading directly from the app. During the project we will also make it easy to use multiple accounts, even across different instances. Additionally, we want to contribute to the Pixelfed API with testing and additional documentation.

Pixelfed Live -- Live streaming and other Pixelfed enhancements

Pixelfed is an open source and decentralised photo sharing platform, in the same vein as services like Instagram. The twist is that you can yourself run the service, or pick a reliable party to run it for you. Who better to trust with your privacy and the privacy of the people that follow you? The magic behind this is the ActivityPub protocol - which means you can comment, follow, like and share from other Pixelfed servers around the world as if you were all on the same website. Timelines are in chronological order, and there is no need to track users or sell their data. The platform has many features including Discover, Hashtags, Geotagging, Photo Albums, Photo Filters and a few still in development like Ephemeral Stories.

WebXray Discovery -- Expose tracking mechanism in search hubs

WebXray intends to build a filter extension for the popular and privacy-friendly meta-search Searx that will show users what third party trackers are used on the sites in their results pages. Full transparency of what tracker is operated by what company is provided to users, who will be able to filter out sites that use particular trackers. This filter tool will be built on the unique ownership database WebXray maintains of tracking companies that collect personal data of website visitors.

Mapping the ownership of tracking companies which sell behavioural profiles of individuals, is critical for all privacy and trust-enhancing technologies. Considerable scrutiny is given to the large players who conduct third party tracking and advertising whilst little scrutiny is given to large numbers of smaller companies who collect and sell unknown volumes of personal data. Such collection is unsolicited, with invisible beneficiaries. The ease and speed of corporate registration provides the opportunity for data brokers to mitigate their liability when collecting data profiles. We must therefore establish a systematic database of data broker domain ownership.

The filter extension that will be the output of the project will make this ownership database visible and actionable to end users, and to curate the crowdsourced data and add it to the current database of ownership (which is already comprehensive, containing detailed information on more than 1,000 ad tech tracking domains).

XWiki -- Bring wiki capabilities into the Fediverse

XWiki is a modern and extensible open source wiki platform. Up until now, XWiki had been focusing on providing the best collaboration experience and features to its users. We're now taking this to the next level by having XWiki be part of the larger federation of collaboration and social software (a.k.a. fediverse), thus allowing users to collaborate externally. XWiki is embracing the W3C ActivityPub specification. Specifically we're implementing the server part of the specification, to be able to both view activity and content happening in external services inside XWiki itself and to make XWiki's activity and content available from these other services too. A specific but crucial use case, is to allow content collaboration between different XWiki servers, sharing content and activity.

librarian -- Custom meta-search

Search engines are the default way of finding information on the internet. Although there is a host of search engines for users to choose - from library catalogs to cooking portals - there is currently only a small number of dominant search engines that practically decide who finds what on the internet. This situation has the following disadvantages: 1) by designing their algorithms these dominant search engines influence our world view, 2) the huge amounts of user data they record, creates sever risks of data leaks and misuse, finally 3) search engines can misuse their market power to gain advantages in other lines of business (e.g. the mobile phone market).

Federated web search is a technology where users connect to a so-called broker which forwards their search request to suitable search engines and combines the results. Using federated search lessens the risks of few dominant search engines: it shows a blend of search results created by different algorithms, it prevents the search engine to record data of individual users, and its search results are usually more divers. Still, for federated web search to become widely used, it faces the following challenges: 1) while exploiting user behavior is known to improve search effectiveness, brokers exploiting this data also risk leaks and misuse, 2) as brokers typically serve many users, they are not able to include search engines for personal content, such as email, social media or cloud storage because the public broker cannot know the user’s credentials to access these services, finally 3) brokers consider for every user the same base set of search engines, while considering a more focused set of engines could improve search results, given the diversity of users.

To improve upon these challenges, while avoiding the disadvantages of dominant search engines, this project will investigate a radical change to the federated search architecture: users run a broker on their own computer using a browser plugin. In this architecture the broker can safely analyze the user's behavior to improve search results as the data is accumulated on a per-user basis on disconnected computers. Furthermore, the search requests forwarded to search engines use the user's credentials and thus can access search engines for personal data, such as email etc. Finally, starting from sensible defaults, each user can configure its broker with his or her individual needs.

MPTCP -- MultiPath TCP

How do you find the best way to communicate with a computer on the other side of the internet? And why bet everything on a single connection? Multipath TCP (MPTCP) extends the most widely used transport protocol on the internet (TCP) so that it can discover and use several physical paths (e.g., Wifi, cellular, between multihomed servers) in parallel. This allows to speed up transfers, smoothly transition from wifi to cellular when leaving one's house or potentially prevent traffic spying.

While the protocol is proven to work well in certain conditions (the fastest TCP connection ever was using MPTCP), it is configuration-sensitive and can degrade badly under adverse conditions (for instance in heterogeneous networks with small buffers). The aim of this project is to provide the tool to help analyze the performance of a multipath protocol as well as the software to (auto)configure the system depending on the application objective and network conditions.

Mailpile Search Integration -- Personal email search engine

Mailpile is an e-mail client and personal e-mail search engine, with a strong focus on user autonomy and privacy. This project, "Mailpile Search Integration", will adapt and enhance Mailpile so other applications can make use of Mailpile's built-in search engine and e-mail store. This requires improving Mailpile in three important ways: First, the project will add fine-grained access control, so the user can control which data is and isn't exposed. Second, enabling remote access will be facilitated, allowing a Mailpile running on a personal device to communicate with applications elsewhere on the network (such as smartphones, or services in "the cloud"). And finally, the interoperability functions themselves (the APIs) need to be defined (building on existing standards wherever possible), implemented and documented.

Mangaki -- Advanced group recommendations

Within a set of search results, what should you do to find the optimal solution for not just a single user but a group? Mangaki is building an open source library for privacy-preserving group recommendations of items. While many content providers suggest recommendations at a personal level, these are often directed to a single user, or are restricted to a generic “family” category. Whenever say a group of friends want to watch a movie, it is often hard to decide what to watch, because people can have really different tastes.

Recommendations are also very privacy-sensitive. A straightforward way might be to share our complete viewing history, but that certainly can lead to embarrassing and awkward situations. So how can we collectively compute a list of relevant items without disclose all of our data unencrypted. The Mangaki project is making an open source library for group recommendations that works in a scalable and distributed way.

Meta-Press.es -- A press search engine in your browser

Meta-Press.es is a press search engine, in the shape of a browser add-on. When using it, everything happens between the user's computer and the queried newspapers. Using Meta-Press.es, there is no data sent to third party (including our servers). We're not asking the users to believe that we respect their privacy, it's a matter of verifiable fact that we do. That means there is no single point of failure, of surveillance or of censorship.

Mynij -- Portable indexing and search engine for mobile

People feel lost when their connection to the internet is cut. All of a sudden, they cannot search for some reference or quickly look up something online. At the other end, hundreds of millions of servers are 'always on', awaiting the user to come online. Of course, this is neither very resilient nor economic. And it is also not necessary. In the 60s, computers used to occupy a large room. Nowadays, with smartphones, they fit in your hand. A complete copy of the Web (10 PB) already fits on 100 SSDs of 100 TB occupying a volume similar to an original IBM PC. A partial copy of the Web optimised for a single person will thus soon fit on a smartphone.

Mynij believes that Web search will eventually run offline for legal, technical and economic rationale. This is why it is building a general purpose Web search engine that runs offline and fits into a smartphone. It can provide fast results with better accuracy than online search engines. It protects privacy and freedom of expression against recent forms of digital censorship. It reduces the cost of online advertising for small businesses. It brings search algorithms and information presentation under end-user control. And you control its availability: as long as you have a copy and a working device, it can work.

Namecoin: ZeroNet and Packaging -- Make ZeroNet work with Namecoin

Namecoin provides a decentralized naming system and trust anchor. Its flagship use-case is a decentralized top-level domain (TLD) which is the cornerstone of a domain name system that is resistant to hijacking and censorship. Among other things, this provides a decentralized trust anchor for Public Key Infrastructure that does not require third party trust. It operates independent from the DNSSEC root trust chain, and can thus offer additional security under some circumstances. ZeroNet is a decentralized web-like network of peer-to-peer users, which provides an alternative to TOR hidden services. In the project, Zeronet will be adapted to support a local Namecoin client, and provide additional assurances such as a Host Header-like mechanism to protect users from spoofing. Namecoin will be used as a human-readable naming layer for Tor onion services and ZeroNet sites. This eliminates the user problem of pseudorandom, unmemorable website addresses for onion services and ZeroNet sites, which can facilitate phishing attacks.

neuropil -- Privacy by design P2P search including IoT

Neuropil is an open-source de-centralized messaging layer that focuses on security and privacy by design. Persons, machines, and applications first have to identify their respective partners and/or content before real information can be sent. The discovery is handled internally and is based on so called "intent messages" that are secured by cryptographic primitives. This project aims to create distributed search engine capabilities based on neuropil, that enable the discovery and sharing of information with significantly higher levels of trust and privacy and with more control over the search content for data owners than today's standard.

As of now large search engines have implemented "crawlers", that constantly visit webpages and categorize their content. The only way to somehow influence the information that is used by search engines is by using a file called „robots.txt“. Other algorithms are only known to the search engine provider. By using a highly standardized "intents" format that protects the real content of users, this model is reversed: data owners define the searchable public content. As an example we seek to implement the neuropil messaging layer with its extended search capabilities into a standard web server to become one actor and to handle and maintain the search index contents of participating data owners. By using the Neuropil messaging layer it is thus possible to build a distributed search engine database that is able to contain and reveal any kind of information in a distributed, concise and privacy preserving manner, without the need for any central search engine provider.

Nextcloud -- Unified and intelligent search within private cloud data

The internet helps people to work, manage, share and access information and documents. Proprietary cloud services from large vendors like Microsoft, Google, Dropbox and others cannot offer the privacy and security guarantees users need. Nextcloud is a 100% open source solution where all information can stay on premise, with the protected users choose themselves. The Nextcloud Search project will solve the last remaining open issue which is unified, convenient and intelligent search and discoverability of data. The goal is to build a powerful but user friendly user interface for search across the entire private cloud. It will be possible to select data date, type, owner, size, keywords, tags and other metadata. The backend will offers indexing and searching of file based content, as well as integrated search for other contents like text chats, calendar entries, contacts, comments and other data. It will integrate with the private search capabilities of Searx. As a result the users will have the same powerful search functionalities they know and like elsewhere, but respecting the privacy of users and strict regulations like the GDPR.

Nyxt -- A programmable browser with advanced search integration

Nyxt is a new type of web browser designed to empower users to find and filter information on the Internet. Web browsers today, largely compete on performance in rendering, all whilst maintaining similar UIs. The common UI they employ is easy to learn, though unfortunately it is not effective for traversing the internet due to its limited capabilities. This presents itself as a problem when a user is trying to navigate the large amounts of data on the Internet and in their open tabs. To deal with this problem, Nyxt offers a set of powerful tools to index and jump around one's open tabs, through search results and the wider Internet. For example, Nyxt offers the ability for the user to filter and process their open tabs by semantic content search. Because each workflow and discipline is unique, the real advantage of Nyxt is in its fully programmable and open API. The user is free to modify Nyxt in any way they wish, even whilst it is running.

Offen -- Privacy-respecting site analytics

Transparently handling data in the open creates mutual trust: Offen is a fair web analytics software that gives users insights into the data they are generating by giving them access to the same suite of analytics tools site operators themselves are using. One unique aspect of Offen is requiring user consent before collecting any data. Especially in countries that are governed by GDPR and its siblings this is a real world requirement for many websites. This is not only about collecting data, but also about embedding third party content or similar.

Usage metrics come with explanations about their meaning, relevance, usage and possible privacy implications, and also details which kind of data is not being collected. Users can expect full transparency and are encouraged to make autonomous and informed decisions regarding the use of their data, and operators are being enabled to collect needed usage statistics while fully respecting their users' privacy and data. No user data is being collected until the user has explicitly opted-in. All data can be deleted either selectively or in its entirety by the users.

Folksonomy engine for the food ecosystem -- Data modelling by the community

Everybody is interested in the food they eat, by many different aspects, ranging from taste, cost, ingredients and nutrition to its impact on health, the environment and society. We also happen to have many different names for the same food, the way we prepare it and other properties - sometimes only used very locally. That means it is not always easy for everyone to effectively search open data sets like OpenFoodFacts. Open Food Facts - sometimes referred to as the "wikipedia for food products" - is the biggest open food-database in the world.

The Folksonomy engine for the food ecosystem created within this project will unleash an ocean of new data and uses regarding food. Citizens, researchers, journalists, professionals, artists, communities, and innovators will be able to define and add new properties of their choice to food products on Open Food Facts for their own use or to enrich the shared knowledge. Open Food Facts already feeds hundreds of data reuses. Thousands more will become possible thanks to the new user defined properties.

Openki.net -- Make local events and meetups discoverable

How do you discover what you can learn from the people around you? How do you search what other people in the same region have to offer, like a training course or a debating event?

Openki is an interface between technology and culture. It provides an interactive web platform developed with the goal to remove barriers for universal education for all. The platform makes it simple to organise and manage "peer-to-peer" courses. The platform can be self-hosted, and integrates with OpenStreetMap. At the moment Openki is focused on facilitating learning groups and workshops. The project will improve the tool, so it can be used not only to organise courses (with the collaboration of many different actors, in a more participatory way) but much broader,for bottom-up project initiation, for grassroot organizations and facilitating societal dialogue.

P2Pcollab -- Decentralised social search and discovery

This project is working towards creating a more decentralized, privacy-preserving, collaborative internet based on the end-to-end principle where users engage in peer-to-peer collaboration and have full control over their own data, enabling them to collaborate on, publish & subscribe to content in a decentralized way, as well as to discover & disseminate content based on collaborative filtering, while allowing local, offline search of all subscribed & discovered content. The project is researching & developing P2P gossip-based protocols and implementing them as composable libraries and lightweight unikernels with a focus on privacy, security, robustness, and scalability.

A Distributed Software Stack For Co-operation -- Facilitating easy ad hoc cooperation

Perspectives aims to be to co-operation, what ActivityPub is to social networks. It provides the conceptual building blocks for co-operation, laying the groundwork for a federated, fully distributed infrastructure that supports endless varieties of co-operation. The declarative Perspectives Language allows a model to translate instantly in an application that supports multiple users to contribute to a shared process, each with her own unique perspective. The project builds a reference implementation of the distributed stack that executes these models of co-operation, and makes the information concerned searchable.

Real life is an endless affair of interlocking activities. Likewise, Perspectives models of services can overlap and build on common concepts, thus forming a federated conceptual space that allows users to move from one service to another as the need arises in a most natural way. Such an infrastructure functions as a map, promoting discovery, decreasing dependency on explicit search. However, rather than being an on-line information source to be searched, such the traditional Yellow Pages, Perspectives models allow their users (individuals and organisations alike) to interact and deal with each other on-line. Supply-demand matching in specific domains (e.g. local transport) integrates readily with such an infrastructure. Other patterns of integrating search with co-operation support form a promising area for further research.

Poliscoops -- Make political news and online debate accessible

PoliFLW is an interactive online platform that allows journalists and citizens to stay informed, and keep up to date with the growing group of political parties and politicians relevant to them - even those whose opinions they don't directly share. The prize-winning polical crowdsourcing platform makes finding hyperlocal, national and European political news relevant to the individual far easier. By aggregating the news political parties share on their websites and social media accounts, PoliFLW is a time-saving and citizen-engagement enhancing tool that brings the internet one step closer to being human-centric. In this project the platform will add the news shared by parties in the European Parliament and national parties in all EU member states. , showcasing what it can mean for access to information in Europe. There will be a built-in translation function, making it easier to read news across country borders. PoliFLW is a collaborative environment that helps to create more societal dialogue and better informed citizens, breaking down political barriers.

PrivateRecSys -- Privacy-Friendly Recommendation System

The use of recommender systems has grown significantly in recent years, with users receiving personalised recommendations ranging from products to buy, news to read, movies to watch, people to follow. At the same time, recommender systems have become extremely effective revenue drivers for online business. However, producing personalised recommendations requires collecting of users’ data, which makes conventional recommenders effective at the cost of users' privacy. The PrivacyRecSys project aims to develop an open-source toolkit for delivering accurate recommendations while respecting users' privacy. The toolkit will consist of novel privacy-preserving recommender approaches, which modify the state-of-the-art recommender approaches by applying the principles of differential privacy, homomorphic encryption and federated learning.

SCION-Swarm -- Secure and reliable decentralized storage platform

With the amount of downloadable resources such as content and software updates available over the Internet increasing year over year, it turns out not all content has someone willing to serve all of it up eternally for free for everyone. And in other cases, the resources concerned are not meant to be public, but do need to be available in a controlled environment. In such situations users and other stakeholders themselves need to provide the necessary capacity and infrastructure in another, collective way.

This of course creates new challenges. Unlike a website you can follow a link to or find through a standard search engine and which you typically only have to vet once for security and trustworthiness, the distributed nature of such a system makes it difficult for users to find the relevant information in a fast and trustworthy manner. One of the essential challenges of information management and retrieval in such a system is the location of data items in a way that the communication complexity remains scalable and a high reliability can be achieved even in case of adversaries. More specifically, if a provider has a particular data item to offer, where shall the information be stored such that a requester can easily find it? Moreover, if a user is interested in a particular information, how does he discover it and how can he quickly find the actual location of the corresponding data item?

The project aims to develop a secure and reliable decentralized storage platform enabling fast and scalable content search and lookup going beyond existing approaches. The goal is to leverage the path-awareness features of the SCION Internet architecture to use network resources efficiently in order to achieve a low search and lookup delay while increasing the overall throughput. The challenge is to select suitable paths considering those performance requirements, and potentially combining them into a multi-path connection. To this end, we aim to design and implement optimal path selection and data placement strategies for a decentralized storage system.

Geographic tagging and discovery of Internet Routing and Forwarding -- Geographic tagging and discovery of Internet Routing and Forwarding

SCION is the first clean-slate Internet architecture designed to provide route control, failure isolation, and explicit trust information for end-to-end communication. As a path-based architecture, SCION end-hosts learn about available network path segments, and combine them into end-to-end paths, which are carried in packet headers. By design, SCION offers transparency to end hosts with respect to the path a packet travels through the network. This has numerous applications related to trust, compliance, and also privacy. By better understanding of the geographic and legislative context of a path, users can for instance choose trustworthy paths that best protect their privacy. Or avoid the need for privacy intrusive and expensive CDN's by selecting resources closer to them. SCION is the first to have such a decentralised system offer this kind of transparency and control to users of the network.

SensifAI -- AI driven image tagging

Billions of users manually upload their captured videos and images to cloud storages such as Dropbox, Google Drive and Apple iCloud straight from their camera or phone. Their private pictures and video material are subsequently stored unprotected somewhere else on some remote computer, in many cases in another country with quite different legislation. Users depend on the tools from these service providers to browse their archives of often thousands and thousands of videos and photo's in search of some specific image or video of interest. The direct result of this is continuous exposure to cyber threats like extortion and an intrinsic loss of privacy towards the service providers. There is a perfectly valid user-centric approach possible in dealing with such confidential materials, which is to encrypt everything before uploading anything to the internet. At that point the user may be a lot more safe, but from now on would have a hard time locating any specific videos or images in their often very large collection. What if smart algorithms could describe the pictures for you, recognise who is in it and you can store this information and use it to conveniently search and share? This project develops an open source smart-gallery app which uses machine learning to recognize and tag all visual material automatically - and on the device itself. After that, the user can do what she or he wants with the additional information and the original source material. They can save them to local storage, using the tags for easy search and navigation. Or offload the content to the internet in encrypted form, and use the descriptions and tags to navigate this remote content. Either option makes images and videos searchable while fully preserving user privacy.

Simmel -- A wearable contact tracing beacon/scanner

Simmel is a platform that enables COVID-19 contact tracing while preserving user privacy. It is a wearable hardware beacon and scanner which can broadcast and record randomized user IDs. Contacts are stored within the wearable device, so you retain full control of your trace history until you choose to share it.

The Simmel design is open source, so you are empowered to audit the code. Furthermore, once the pandemic is over, you are able to recycle, re-use, or securely destroy the device, thanks to the availability of hardware and firmware design source.

The contact tracing algorithm is programmed using CircuitPython, to facilitate ease of code audit and community participation. The Simmel project does not endorse a specific contact tracing platform, but it is inherently not compatible with contact tracing proposals that rely on the constant upload of data to the cloud.

Solid-NextCloud app -- Bridge Nextcloud to Solid

This project connects the world of Solid with the world of Nextcloud. The aim is to develop an open source Nextcloud app that turns a Nextcloud server into a spec-compliant Solid server. It gives every user a WebID profile and allows Solid apps to store data on the user's Nextcloud account. It also exposes some of the user's existing Nextcloud data like contacts and calendar events as Solid user data, so that Solid apps can interact with the user's Nextcloud data, and allow the user to manage which Solid apps can access which specific aspects of the user's personal data. We will make our implementation compatible with the latest version of the Solid spec (including DPop tokens and the WebSockets AUTH command), and contribute the surface tests we create for this as a well-documented independent test-suite, for other Solid server implementers to benefit from. We will also publish a stand-alone version of our PHP components, which can run independently of Nextcloud.

StreetComplete -- Fix open geodata with OpenStreetMap

The project will make collecting data for OpenStreetMap easier and more efficient. OpenStreetMap is the best source of information for general purpose search engines that need a geographic data about locations and properties of various objects. The objects vary from cities and other settlements to shops, parks, roads, schools, railways, motorways, forests, beaches etc etc etc. The search engine can use the data to answer queries such as "route to nearest wheelchair accessible greengrocer", "list of national parks near motorways" or "London weather". Full OpenStreetMap dataset is publicly available on an open license and already used for many purposes. Improving OSM increases quality of services using open data rather than proprietary datasets kept as a trade secret by established companies.

Transparency Toolkit -- A decentralized hosted archiving service with search

Transparency Toolkit is building a decentralized hosted archiving service that allows journalists, researchers, and activists to create censorship-resistant searchable document archives from their browser. Users can upload documents in many different file formats, run web crawlers to collect data, and manually contribute research notes from a usable interface. The documents are then OCRed (when needed) and indexed in a searchable database. Transparency Toolkit provides a variety of tools to help analyze and understand the documents with text mining, searching/filtering, and manual collaborative analysis. Once users are ready, they can make some or all of the documents available in a public searchable archive. These archives will be automatically mirrored across multiple instances of the software and the raw data will be stored in a distributed fashion.

URL Frontier -- Develop a API between web crawler and frontier

Discovering content on the web is possible thanks to web crawlers, luckily there are many excellent open source solutions for this; however, most of them have their own way of storing and accessing the information about the URLs. The aim of the URL Frontier project is to develop a crawler-neutral API for the operations that a web crawler when communicating with a web frontier e.g. get the next URLs to crawl, update the information about URLs already processed, change the crawl rate for a particular hostname, get the list of active hosts, get statistics, etcetera. It aims to serve a variety of open source web crawlers, such as StormCrawler, Heritrix and Apache Nutch.

The outcomes of the project are to design a REST API with OpenAPI then provide a set of client APIs using Swagger Codegen as well as a robust reference implementation and a validation suite to check that implementations behave as expected. The code and resources will be made available under Apache License as a sub-project of crawler-commons, a community that focuses on sharing code between crawlers. One of the objectives of URL Frontier is to involve as many actors in the web crawling community as possible and get real users to give continuous feedback on our proposals.

variation graph (vgteam) -- Privacy enhanced search within e.g. genome data sets

Vgteam is pioneering privacy-preserving variation graphs, that allow to capture complex models and aggregate data resources with formal guarantees about the privacy of the individual data sources from which they were constructed. Variation graphs relate collections of sequences together as walks through a graph. They are traditionally applied to genomic data, where they support the compression and query of very large collections of genomes.

But there are many types of sensitive data that can be represented in a variation graph form, including geolocation trajectory data - the trajectories of individuals and vehicles through transportation networks. Epidemiologists can use a public database of personal movement trajectories to for instance do geophylogenetic modeling of a pandemic like SARS-CoV2. The idea is that one cannot see individual movements, but rather large scale flows of people across space that would be essential for understanding the likely places where a outbreak might spread. This is essential information to understand at scientific and political level how to best act in case of a pandemic, now and in the future.

The project will apply formal models of differential privacy to build variation graphs which do not leak information about the individuals whose data was used to construct them. For genomes, the techniques allow us to extend the traditional models to include phenotype and health information, maximizing their utility for biological research and clinical practice without risking the privacy of participants who shared their data to build them. For geolocation trajectory data, people can share data in the knowledge that their social graph is not exposed. The tools themselves are not limited to the above use cases, and open the doors to many other types of applications both online (web browsing histories, social media usage) and offline. .

Web Annotation -- Building blocks for interoperable annotation systems

The idea of web annotation is to support the creation and exchange of annotations on any visited page; thereby enabling people to make, share, and discover corrections, rebuttals, side-notes, or other contextually relevant resources. Using the W3C’s Web Annotation standard, and contributing to the incubating Apache Annotator project, this project works on modules and tools that facilitate a diverse ecosystem of interoperable annotation systems.

elRepo.io - Resilient, human-centered, distributed content sharing and discovery. -- Resilient, human-centered, distributed content sharing and discovery.

In this project AlterMundi and NetHood collaborate to develop a critical missing part in decentralized and distributed p2p systems: content search. More specifically, this project will implement advanced search for elRepo.io, the self-hosted and distributed culturesharing platform currently under active development by AlterMundi and partners. Search functionalities will expand on the already proven coupling of thelibxapian searching and indexing library and turtle routing. The distributed search functionality will be implemented to be flexible and modular. It will become the meeting point of three complementary threads of on-going work: Libre technology and tools for building Community Networks (LibreRouter & LibreMesh), fully decentralized, secure and anonymous Friend2Friend software (Retroshare), and a transdisciplinary participatory methodology for local applications in Community Networks (netCommons).

Handling Data from IPv6 Scanning -- Scanning tools for scaling up IPv6 scans

Scanning is state of the art to discover hosts on the Internet. Today’s scanning relies on IPv4 and simply probes all possible addresses. But global IPv6 adoption will render brute-forcing useless due to the sheer size of the IPv6 address space, and demands more sophisticated ways of target generation. Our team developed such an approach that generally allows to probe all subnets in the currently deployed IPv6 Internet within reasonable time. Positive responses are however scarce in the IPv6 Internet; thus, we include error messages in our analysis as they provide meaningful insight into the current deployment status of networks. First experiments covering only parts of the Internet were promising and at least 5% of our probes trigger error messages. However, a full scan would lead to approx. 10^14 responses causing Petabytes of data, and demands an adequate solution of data handling. In this project, we will develop a data storage and analysis solution for high-speed IPv6 scanning. It will process the high amount of received data concurrently with scanning, and provide continuous results while scanning for long periods. This effort enables full scans of the IPv6 Internet.

Software vulnerability discovery -- Automating discovery of software update and vulnerabilities

nixpkgs-update automates the updating of software packages in the nixpkgs software repository. It is a Haskell program. In the last year, about 5000 package updates initiated by nixpkgs-update were merged. This project will focus on two improvements: One, developing infrastructure so that the nixpkgs-update can run continuously on dedicated hardware to deliver updates as soon as possible, and Two, integrating with CVE systems to report CVEs that are addressed by proposed updates. I believe these improvements will increase the security of nixpkgs software and the NixOS operating system based on nixpkgs.

Privacy Preserving Disease Tracking -- Research into contact tracing privacy

In case of a pandemic, it makes sense to share data to track the spread of a virus like SARS-CoV2. However, that very same data when gathered in a crude way is potentially very invasive to privacy - and in politically less reliable environments can be used to map out the social graph of individuals and severely threaten civil rights, free press. Unless the whole process is transparent, people might not be easily convinced to collaborate.

The PPDT project is trying to build a privacy preserving contact tracing mechanism that allows to notify users if they have come in contact with potentially infected people. This should happen in a way that is as privacy preserving as possible. We want to have the following properties: the users should be able to learn if they got in touch with infected parties, ideally only that - unless they opt in to share more information. The organisations operating servers should not learn anything besides who is infected, ideally not even that. The project builds a portable library that can be used across different mobile platforms, and a server component to aggregate data and send this back to the participants.

Search and Displace -- Find and redact privacy sensitive information

The goal of this project is to establish a workflow and toolchain which can address the problem of mass search and displacement for document content where the original documents are in a range of forms, including a wide variety of digital document formats, both binary and more modern compressed XML forms, and potentially even encompassing older documents where the only surviving form is printed or even handwritten. The term "displacement" is meant to encompass actions taken on the discovered content that are beyond straight replacement, including content tagging and redaction, as well as more complex contextual and user-refined replacement on an iterative basis. It is assumed that this process will be a server application with documents uploaded as needed, on either an individual or bulk upload basis. The solution would be built in a modular fashion so that future deployments could deploy and/or modify only the parts needed. In practical terms this involves the creation of an open source tool chain that facilitates searching for private and confidential content inside documents, for instance attachments to email messages or documents that are to be published on a website. The tool can subsequently be used for the secure and automated redaction of sensitive documents; by building this as a modular solution enables the solution to be used “standalone” with a simple GUI, or used via command line, or embedded within 3rd party systems such as document management systems, content management systems and machine learning systems. In addition a modular approach will facilitate the use of the solution both with different languages (natural and programming) and different specialities e.g. government archives, winning tenders, legal contracts, court documents etc..

fwupd -- Automatic Firmware updates for BSD operating systems

Security holes in the equipment we run are discovered all the time, and firmware is continuously upgraded as a result. But how do users discover what they need to upgrade to protect themselves? The goal of the "fwupd/LFVS integration in the BSD distributions" is to reuse the effort done by the fwupd/LVFS project and make it available in the BSD-based systems as well. The fwupd is available on Linux-based systems since 2015. It is an open-source daemon for managing the installation of firmware updates from LVFS. The LVFS (Linux Vendor Firmware Service) is a secure portal which allows hardware vendors to upload firmware updates. Over the years, some major hardware vendors (e.g. Dell, HP, Intel, Lenovo) have been uploading their firmware images to the LVFS so they can be later installed on the Linux-based systems. The integration of the fwupd in the BSD-based systems would allow reusing the well-established infrastructure so more users can take advantage of it.

Free Software Vulnerability Database -- A resource to aggregate software updates

"Using Components with Known Vulnerabilities" is one of the OWASP Top 10 Most Critical Web Application Security Risks. Identifying such vulnerable components is currently hindered by data structure and tools that are (1) designed primarily for commercial/proprietary software components and (2) too dependent on the National Vulnerability Database (from US Dept. of Commerce). With the explosion of Free and Open Source Software (FOSS) usage over the last decade we need a new approach in order to efficiently identify security vulnerabilities in FOSS components that are the basis of every modern software system and applications. And that approach should be based on open data and FOSS tools. The goal of this project is create new FOSS tools to aggregate software component vulnerability data from multiple sources, organize that data with a new standard package identifier (Package URL or PURL) and automate the search for FOSS component security vulnerabilities. The expected benefits are to contribute to the improved security of software applications with open tools and data available freely to everyone and to lessen the dependence on a single foreign governmental data source or a few foreign commercial data providers.

Discover and move your coins by yourself -- A safe way to explore and work with cryptocurrency forks

The numerous technologies behind cryptocurrencies are probably the most difficult to understand compared to any other networks, even for technical experts - and especially bitcoin based networks. Most users, even those familiar with the technology for years, have to rely on wallets or run/sync full nodes. Empirically we can see that they usually get lost at a certain point of time, especially when said wallets dictate the use of new "features", like bip39 and alike, multisig, segwit and bech32. Most users don't understand where their coins are and on what addresses, what is the format of these addresses and what are their seeds and what they need to unlock their coins. This situation pushes users to give their private keys to dubious services, resulting to the loss of all of their coins. The alternative is to let exchanges manage their coins, which removes their agency and puts them at risk. The goal of this project is to correct this situation allowing people to simply discover where are their coins and what are their addresses, whatever features are used. It will allow them to discover their addresses from one coin to another, rediscover their seed if they lost a part, sign/verify addresses ownership, discover public keys from private keys and create their hierarchical deterministic addresses. In fact, all the tools needed to discover and check what is related to their coins - and this for any bitcoin based network, in addition it allows them to create their transactions by themselves and send them to the networks, or just check them. The tool is a standalone secure open source webapp inside browsers that must be used offline, this is a browserification of a nodejs module that can be also used or modified for those that have the technical knowledge.

GNU Name System -- Authenticated naming system for the internet from GNU project

Today, the starting point of any discovery on the Internet is the Domain Name System (DNS). DNS suffers from security and privacy issues. The GNU project has developed the GNU Name System (GNS), a fully decentralized, privacy-preserving and end-to-end authenticated name resolution protocol. In this project, we will document the protocol on a bit-level (RFC-style) and create a second independent implementation against the specification. Furthermore, we will simplify the installation by providing proper packages that, when installed, automatically integrate the GNS logic into the operating system.

Connect by Name -- Library for easy connection setup

Connect by Name will be a C library providing an interface that allows a software developer to setup internet connections from an application in the most private and secure manner using well-established and open standards. The interface provided to the software developer will be as simple as “Connect to a service on a domain name” and be flexible enough to fit with different programming paradigms and environments. The library will facilitate composability with other systems and will be extensible with future standards. Our goal is to lower the barrier for developing high-quality software and thereby improve the security and privacy of end users.

Interpeer -- Collaboration infrastructure with near real-time p2p data synchronization

The Interpeer Project's purpose is to research and develop novel peer-to-peer technologies for open and distributed software architectures. The goal is to enable serverless modes of operation for collaborative software with rich feature sets equal to or surpassing centralized client-server architectures. For that reason, the initial focus lies on facilitating the extreme end of the use case spectrum with very low latency and high bandwidth requirements, as exemplified by peer-to-peer video communications in quality as close to 4k resolution as possible. When that initial goal is reached, the project focus will shift to other collaboriative applications of the technology.

LibreOffice P2P -- Encrypted collaborative editing in the browser

LibreOffice Online is the online version of the popular open source office application, and a leading implementation of the ISO/IEC 26300 OpenDocument Format standard. During the project this free software application will be modified so it can run fully client-side inside a regular browser - meaning you can view and edit office documents without an install required. This provides the technical foundations to support true P2P editing of complex office documents. The ability to remove the entire dependency on a server means that document collaboration is moving towards zero-knowledge implementations – where no single-point of architectural failure exists and no data is required to sit unencrypted on a non-user owned (or trusted) server instance. The improved LibreOffice Online will be able to provide end-to-end encryption – both for the peer2peer use case, as well as securely keeping documents encrypted when at rest. That means data is safe when the user is disconnected, whether it is stored on an untrusted server or in the local Web storage.

Librecast Live -- Live streaming with multicast

The Librecast Live project contributes to decentralizing the Internet by enabling multicast. Multicast is a major network capability for a secure, decentralized and private by default Next Generation Internet. The original design goals of the Internet do not match today's privacy and security needs, and this is evident in the technologies in use today. There are many situations where multicast can already be deployed on the Internet, but also some that are not. This project will build transitional protocols and software to extend the reach of multicast and enable easy deployment by software developers. Amongst others it will produce a C library and POC code using a tunneling method to make multicast available to the entire Internet, regardless of upstream support. We will then use these multicast libraries, WebRTC and the W3C-approved ActivityPub protocol to build a live streaming video service similar to twitch.tv. This will be a complement to the existing decentralised Mastodon and Peertube projects, and will integrate with these services using ActivePub. By doing so we can bring live video streaming services to these existing decentralised userbases and demonstrate the power of multicast at the same time. Users will be able to chat and comment in realtime during streaming (similar to YouTube live streaming). This fills an important gap in the Open Source decentralised space. All video and chat messages will be transmitted over encrypted channels.

Lizard -- E2E Rendez-vous and discovery

The Lizard project aims to develop a common protocol for end-to-end encrypted social applications using Tor as underlying transport mechanism, with the addition of store-and-forward servers discovered through the Tor hidden service directory. The protocol takes care of confidentiality and anonymity concerns, and adds mechanisms for easily synchronising application-level state on top. All communications are done "off the grid" using Tor, but identities can be publicly attested to using existing social media profiles. Using a small marker in your social profiles, you can signal to other Lizard users that they can transparently message you over Lizard instead. By taking care of these common discovery and privacy concerns in one easy-to-use software suite, we hope that more applications will opt for end-to-end encryption by default without compromising on anonymity.

In-document search -- Interoperable Rich Text Changes for Search

There is a relatively unexplored layer of metadata inside the document formats we use, such as Office documents. This allows to answer queries like: show me all the reports with edits made within a timespan, by a certain user or by a group of users. Or: Show me all the hyperlinks inside documents pointing to a web resource that is about to be moved. Or: list all presentations that contain this copyrighted image. Such embedded information could be better exposed to and used by search engines than is now the case. The project expands the ODF toolkit library to dissect file formats, and will potentially have a very useful side effect of maturing the understanding of document metadata at large and for collaborative editing of documents in particular.
