The Web Service Business Process Execution Language (WS-BPEL) and theWeb Service Choreography Description Language (WS-CDL) are two important standards for modelling and implementing workflows and business processes based on Web services. From the WS-CDL description of a Web services based business process, we may extract a behavioural specification against which the combined behaviour of the participating Web services should be verified. We show how to express this behavioural specification as well as the behaviour of individualWS-BPEL-based Web services in the formalism of Communicating Sequential Processes (CSP), which supports a formal approach to verifying the behaviour of collaborating Web services.
