In this paper we propose a semantic based P2P system that incorporates peer sharing policies, which allow a peer to state, for each of the concepts it deals with, the conditions under which it is available to process requests related to that concept. The semantic routing approach, based on advertisements and peer behavior in answering previous requests, takes also into account sharing policies.
