The Web Service Business Process Execution Language (WS-BPEL) and the Web 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 individual WS-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.
