Since we are currently editing the WSA spec, we need a placeholder for the notions of Choreography and probably orchestration. I propose the following: Choreography: The pattern of interactions, expressed as a pattern of types of messages, between a set of service requestors and providers. A description of a choreography may include a description of the necessary states that give rise to the particular message patterns. In contract, Orchestration would be: A mechanism for ensuring that a set of service providers and requestors exchange messages in accordance to a choreography. We would appreciate comments on these definitions, as a new heart-beat spec will be published shortly. Of course, if WS-CHOR comes to consensus on these terms, the WSA will be updated acccordingly.
