WS-Coordination defines a framework for establishing protocols for coordinating the outcome agreement within distributed applications. The framework is extensible and allows support for multiple coordination protocols. To facilitate the realization of new coordination protocols we present a model-driven approach for the generation of BPEL processes used as implementation of coordination protocols. We show how coordination protocols can be modeled in domain-specific graph-based diagrams. Then we describe how to transform such graphs into abstract BPEL process models representing the behavior of the coordinator and the participants in the protocol. We present a prototypical implementation of the approach.
