In service oriented computing, choreography languages are used to specify multi-party service compositions. Two main approaches have been followed: the interaction-oriented approach of WS-CDL and the process-oriented approach of BPEL4Chor. We investigate the relationship between them.In particular, we consider several interpretations for interaction-oriented choreographies spanning from synchronous to asynchronous communication. Under each of these interpretations we characterize the class of interaction-oriented choreographies which have a process-oriented counterpart, and we formalize the notion of equivalence between the initial interaction-oriented choreography and the corresponding process-oriented one.

Abstract
In service oriented computing, choreography languages are used to specify multi-party service compositions. Two main approaches have been followed: the interaction-oriented approach of WS-CDL and the process-oriented approach of BPEL4Chor. We investigate the relationship between them.In particular, we consider several interpretations for interaction-oriented choreographies spanning from synchronous to asynchronous communication. Under each of these interpretations we characterize the class of interaction-oriented choreographies which have a process-oriented counterpart, and we formalize the notion of equivalence between the initial interaction-oriented choreography and the corresponding process-oriented one.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
