Processes as Services: Contract Design for Services that Encapsulate WS-BPEL Process Definitions http://www.soamag.com/I12/1107-3.asp Now that WS-BPEL 2.0 has become a ratified industry standard, it is making its way into the IT mainstream and is therefore becoming important to the design of SOA implementations comprised of Web services. This article provides an exploration of the design of WSDL definitions for Web services required to encapsulate WS-BPEL process logic. Because SOA advocates a "contract first" approach to the design of services, understanding the unique service contract design consideration raised by WS-BPEL is a key success factor to building effective process and task services.
