A Model Driven Approach for Web Service Composition

Abstract

We propose a model driven approach for web services composition, a way allowing specifying web services and their composition at a high level of abstraction and generating the implementation of such composition. Web services are described by WSDL (Web Service Description Language), and then translated into high-level models, which can be composed according to a composition scheme. The MDA (Model Driven Architecture) is used to support our approach for generating BPEL code and WSDL Description from the high-level web service models. A case study highlights the benefits of our proposal and illustrates the automatic generation of web services composition.
