An approach for adapting web services

The evolution of Web services becomes necessary because it is inevitable that services will evolve overtime and clients will always ask for new features. Unfortunately the current standards do not support necessary mechanisms to ensure the behaviour evolution of the Web services. This problem becomes more complex for dynamically adaptation and for Web service upgrade by non-backwards-compatible changes. In this paper we present an approach to manage the behaviour evolution of Web services and adapt dynamically their clients by providing a set of change operators for services and a set of adaptation rules for clients. This approach is validated within a framework proposed at the end of this paper.
