Abstract
The Web services architecture defines separate specifications for the composition and the coordination of Web services. BPEL is a language for creating service compositions in the form of business processes, whereas the WS-Coordination framework defines coordination protocols for distributed activities. In this paper, we investigate the combination of these two aspects to compose coordinated Web services. We argue for a policy-based approach to address this problem and introduce a new model and middleware that enables the flexible integration of diverse coordination types into (existing) process-based Web services compositions. © IFIP International Federation for Information Processing 2004.
