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.
