Policies for cooperative hypermedia systems: concepts and prototype implementation Samir Tata, Claude Godart, and Uffe Kock Wiil   View Paper (PDF)   Return to Next-Gen Open Hypermedia, Part Two Abstract The objective of this work is to develop a cooperative hypermedia framework that enables actors to cooperatively create, use, and modify versioned hypermedia documents. A rich set of cooperation policies, based on hypermedia documents, access rights, and synchronization contracts, have been defined to support flexible cooperation control.
