On Collaborations and Choreographies

This paper analyzes binary collaborations and multi-party collaborations in the context of business processes and proposes a lifecycle in which collaborations are first represented with abstract models called collaboration processes, then embodied in business processes and finally implemented in BPEL. In particular this paper discusses how to represent multi-party collaborations and presents two approaches: one is based on binary collaborations complemented with choreographies, and the other draws upon the notion of extended binary collaborations.
