Abstract

WS-CDL (Web Service Choreography Description Language) is a language to describe multiple party how to work with together to accomplish a work in the context of SOA. BEPL (Business Process Execution Language) can get the same point, but they are from different view. WS-CDL is from a global view, which describes how multiple parties communicate with each other. BPEL is from a point of view of a single role who participates to manage the process of the work. Usually these two ways work together to describe and implement the business process. But WS-CDL has more advantages to achieve the most important goal of SOA-flexibility. So, W3C gives a suggestion to create an algorithm mapping from WS-CDL to BPEL; this chapter describes such a way to accomplish this.
