Report B 05-14
In a previous technical report TR-B-04-11 we have introduced an extension of XML-based tuplespaces for the Semantic Web. By applying a tuplespace approach to the concurrent interaction of multiple clients with distributed knowledge repositories, we foresee the benefits of a simple yet powerful co-ordination model in which parallel and distributed processes can be uncoupled in space and time. The proposed system has been called Semantic Web Spaces and is envisaged as acting as a middleware platform for real world Semantic Web applications, in which it can handle in place of the client the administration of distributed data, co-ordination of multiple processes and mediation between ontological representations. This technical report outlines a conceptual model for Semantic Web Spaces. It provides answers to the questions that arise when trying to combine the Linda/tuplespace paradigm with the Semantic Web and Semantic Web compatible knowledge representations. Considering the sorts of extensions that can be made to Linda-based systems, we identify those extensions which are required for an integration with the Semantic Web. As a result, we can give a clearer overview of how Semantic Web Spaces would be implemented and function. As a complementary activity, we also provide in the separate technical report TR-B-05-15 a concrete use case for applying Semantic Web Spaces to realize ontology repositories.
