Modeling Service Choreographies Using BPMN and BPEL4Chor

Abstract. Interconnecting information systems of independent business partners requires careful specification of the interaction behavior the different partners have to adhere to. Choreographies define such inter-action constraints and obligations and can be used as starting point for process implementation at the partners ’ sites. This paper presents how the Business Process Modeling Notation (BPMN) and the Business Process Execution Language (BPEL) can be used during choreography design. Step-wise refinement of choreographies to the level of system configuration is supported through different language extensions as well as a mapping from BPMN to BPEL4Chor. A corresponding modeling environment incorporating the language mapping is presented.
