Structuring the System Layer with Dataspaces

[Structuring the System Layer with Dataspaces]

The system layer is an essential but often-ignored part of an operating system, mediating between user-facing programs and the kernel. Despite its importance, the concept has only been recently recognised and has not received a great deal of attention. The novel Dataspace Model of concurrency and communication combines a small number of concepts to yield succinct expression of ubiquitous system-layer features such as service naming, presence, discovery and activation; security mechanism and policy; subsystem isolation; and robust handling of partial failure. This project will evaluate the hypothesis that the Dataspace Model provides a suitable theoretical and practical foundation for system layers, since a well-founded system layer is a necessary part of any vision of secure, securable, resilient networked personal computing.
