On the one hand, Petri net models have a successful history in the modeling, simulation, and verification of workflows and business processes. On the other hand, BPEL is the de facto standard for describing and implementing Web service-based business processes. With abstract BPEL processes, BPEL can also be used as modeling language. However, being a complicated language with many syntactic constraints, abstract BPEL processes impede a straightforward modeling. In this paper, the authors introduce a fully-automatic translation of Petri net models into abstract BPEL processes which can be easily refined to executable BPEL processes.
