Federated Timesheets

Interoperable machine-readable time tracking

This project brings together developers from WikiSuite,, Muze and Ponder Source in a collaboration to deliberately research how federated machine-readable data can work between independent software projects on the user-operated internet. We want to showcase how our vision of Federated Bookkeeping can make internet users "connected but sovereign".

Each project’s timesheet system that tracks billable hours will be extended with time tracker apps (locally or on a self-hosted server) to expose machine-readable timesheet data through a query endpoint (reader pull) or through a webhook (writer push).

Furthermore a W3C interest group “federated timesheets” was started that will contain and maintain a repository of time tracker schemas and extend this continuously in an orderly fashion to enable developers to import recipients’ schemas as well as add their own to the repository.
