Supporting Web Service Protocol Changes by Propagation

Very often, enterprises are subject to changes. These changes require adaptations regarding business process, security components, database access, etc. In this paper we present a comprehensive (basic) approach for the controlled evolution of Web service business protocols in a cooperative Web services framework. A set of elementary change operators is proposed to capture the change of protocols and a selective process of change projection is adopted to predict potentially interesting changes to partners in order to maintain compatibility.
