although this project is a little silent (at least to my knowledge) it is surely interesting as a storage backend for Semantic Web Resources on a local desktop.
gnome-Storage managed by Seth Nickell.
In fenfire by Benja Fallenstein and in Stefan Decker’s distributed P2P Semantic Desktop we will need a local storage for Resources, that is able to be accessed from normal Desktop Applications and that can be used to add RDF metadata to objects. And storage does more: it has global unique identifiers, and even better: it has URLs that are bound to hosts. great, i love it.
Best part is, that “storage” is done by some core gnome developers and so it will probably have good acceptance in the community.
The bad message is that the developer page looks dusty.
