Abstract
In order to fully exploit the potential of dynamic service-oriented architectures based on Web Services we provide a novel self-integration service infrastructure that supports automatic service discovery and reconfiguration for BPEL4WS processes. Our service discovery approach takes into account possible runtime transformations such that a service in a BPEL4WS process can be replaced by a semantically similar service even if service interfaces and message structures do not match. We present the main building blocks of our solution, i.e. a standard-conformant WSDL schema extension called Mediation Contract Extension (MECE), a corresponding semantic discovery algorithm, and a runtime mediation system that generates appropriate XSLT transformations on the fly. Our solution dynamically instantiates mediators to bind services to service processes specified with BPEL4WS.
