Transformation BPEL processes to RECATNet for analysing Web services compositions

One of the most important advantages of Web services technology is the possibility of combining existing services to create a new composite Web process according to the given requirements. BPEL is a promising language which describes web service composition in form of business processes. However, BPEL is an XML-based language and lack of a sound formal semantic, which hinders the formal analysis and verification of business processes specified in it. In this paper, we propose an approach based RECATNet to model and verify BPEL processes. We present some transformation rules of BPEL business processes into RECATNet. Since RECATNets semantics may be defined in terms of the conditional rewriting logic, Maude tools may be used for model-checking the correctness of BPEL processes. A case study is given to show the efficiency of our approach.
