Web Service Orchestration and Choreography

The following is the explainations of the "Web service orchestration" and "Web service choreography"[1].

 

 

Orchestration == Executeable Process

Web Service Orchestration relates to the execution of specific business processes. WS-BPEL is a language for defining processes that can be executed on an orchestration engine.

 

Choreography == Multi-party Collaboration

Web Service Choreography relates to describing externally observable interactions between web services. WS-CDL is a language for describing multi-party contracts and is somewhat like an extension of WSDL: WSDL describes web services interfaces, WS-CDL describes collaborations between web services.
