Visualizing B2Bi choreographies

The implementation of cross-organizational processes in the context of Business-to-Business integration (B2Bi) requires extensive communication between all interacting parties and adequate solutions for the integration of existing IT systems. In the SOA domain, choreography languages have been put forward for the specification of the publicly visible message exchange sequences of interacting parties. Choreography models serve as basis for communication between stakeholders and as reference for aligning business services which is a core SOA concept. However, visual choreography modeling guidelines that are both, tailored to B2Bi and unambiguous in semantics, have not been proposed so far. This paper fills in this gap by showing how BPMN choreography notation can be used to represent so-called B2Bi choreographies with unambiguous semantics. The work has been validated by a series of real-world use cases of the RosettaNet community and has been accepted by the RosettaNet Message Control and Choreography team as core part of a RosettaNet standard.
