A Tuplespace-Based Middleware for Semantic Web Services Using SWRL

Coordination is a vital aspect of any type of interaction between computer agents in open distributed systems such as the Web. As distributed systems become more ubiquitous, autonomous and complex, the need to ground them on common data model grows stronger. In particular, Semantic Web services are based on synchronous message exchange, thus being incompatible with the REST architectural model of the (Semantic) Web. Recent advances in middleware technologies propose semantic aware tuplespaces as an infrastructure for coping with these issues. However, all of the existing related works do not support rule in their extensions of tuplespace. This paper presents a RuleSpaces based on a combination of tuplespace computing and Semantic Web Rule Language. We describe overview of the conceptual model and discuss the necessary extensions to the original tuplespace. An initial version of the RuleSpaces prototype system has been implemented.
