SAWSDL for Self-adaptive Service Composition

In this paper we present our experience in using SAWSDL for supporting the dynamic replacement of services inside a service composition even in presence of syntactic mismatches between service interfaces. We illustrate the guidelines we defined for adding semantic annotations to WSDL based service interface descriptions. We also present the case studies we implemented to apply our approach to some actual service oriented scenarios. Basing on the current results of our work, we finally evaluate the feasibility of using SAWSDL for solving mismatches between service interfaces at different levels and we propose some extensions.
