Visualizing B2Bi choreographies

Abstract

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 socalled 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.

Establishing Conformance between Contracts and Choreographies

“…For choreography specification, we have chosen the RosettaNet Methodology for Creating Choreographies [11], [12] which is a restricted version of BPMN 2.0 [1], yet it offers the right abstractions and simplifications (business operation with normal and exceptional outcomes, synchronised outcomes and so on) for modelling B2B interactions at the level of the process domain (see Fig. 1).…”

“…In parallel, a great variety of choreography languages have also been suggested [19], [20] with focus on modelling different aspects of choreography processes. In [12] the author argues that existing choreography languages are too general and consequently not entirely satisfactory for modelling B2B integration (B2Bi). In particular, the author criticises the excess of constructs offered by BPMN and its lack of semantics for modelling B2Bi choreographies.…”
