Choreography and Orchestration: A Synergic Approach for System Design

Abstract. Choreography and orchestration languages deal with business processes design and specification. Referring to Web Services technology, the most credited proposals are WS-CDL about choreography and WS-BPEL about orchestration. A closer look to such a kind of languages highlights two distinct approaches for system representation and management. Choreography describes the system in a top view manner whereas orchestration focusses on single peers description. In this paper we define a notion of conformance between choreography and orchestration which allows to state when an orchestrated system is conformant to a given choreography. Choreography and orchestration are formalized by using two process algebras and conformance takes the form of a bisimulation-like relation.
