What is the OpenKnowledge project? In a nutshell, OpenKnowledge is a system which allows peers on an arbitrarily large peer-to-peer network to interact productively with one another without any global agreements or pre-run-time knowledge of who to interact with or how interactions will proceed. Any kind of service (e.g., a WSDL service) can become a peer or else we provide facilities for users to easily create their own peer, by sharing existing code or writing their own.
The OpenKnowledge team responded to the UK's Grand Challenge Project for information-driven healthcare with a proposal to "completely change the way patients view the management of their healthcare pathways."
