Abstract

The specification of a Web service, described with languages like WSFL, XLANG, BPEL4WS, is mainly the description of its observable behaviour based on the messages exchanged with the client. This behaviour is non deterministic due to the internal choices of the server. Furthermore the specification often includes timing constraints. Building applications using Web service requires controlling interaction with them. To this end, we propose a formal dense time semantical approach based on timed automata to first describe service specifications and then to build correct interacting clients when possible. The present work extends our previous discrete time approach and overcome its limitations.
