Abstract
We discuss the problem of semantic data integration in a highly-dynamic environment consisting of a community of peer-to-peer cooperating agents (partners). Peers decide when to join and when to leave the system, how to describe their local data, when to communicate and share their resources with partners. An agent issues queries to its partners (friends) which are able partly answer the query and then propagate the query to their partners along semantic paths existing in the system. Semantic paths are determined by schema mappings defined between partners. We propose a method for specifying schema mappings and to translate them to XQuery expressions. Mappings are represented by means of logical formulas. We also propose a declarative specification of semantic-driven communication in the system. The specification is made in a peer-oriented extension of Prolog.
