Mapping BPMN2 Service Choreographies to Colored Petri Nets

Nowadays, software systems are often built by reusing and integrating existing services distributed over the Internet. Service choreography is a service engineering approach to compose together and coordinate services by specifying their external interactions in terms of flows of peer-to-peer message exchanges, given from a global perspective. BPMN2 offers a dedicated notation, called Choreography Diagrams, to specify service choreographies. However, BPMN2 specifications lack formal semantics causing some misinterpretations by practitioners and researchers. Colored Petri Net (CPN) is a formally proved notation with mathematical semantics and tool support for different analysis techniques. In this paper, we present a mapping to transform BPMN2 Choreography Diagrams into Colored Choreography Nets (CCNs). The latter is a CPN for enabling simulation and analysis of servicechoreographies.
