model-driven engineering of composite web services using uml-s
Based on top of Web protocols and XML language, Web services are emerging as a framework to provide application-to-application interaction. An important challenge is their integration in order to provide new value-added composite services, allowing consequently Business-to-Business relationships. Therefore, many composition languages have been proposed in the past few years. However, a weakness of these languages is that they are difficult to use in early stages of development, such as specification. Thus, an extension to UML 2.0, named UML-S, was introduced to develop composite Web services conforming to the model-driven engineering vision. This paper introduces the necessary transformation rules between UML-S and low-level code to comply with MDE approach.
