Written by developers from BEA Systems, IBM, and Microsoft, BPEL combines and replaces IBM's WebServices Flow Language (WSFL) and Microsoft's XLANG specification. (BPEL is also sometimes identified as BPELWS or BPEL4WS.) Using BPEL, a programmer formally describes a business process that will take place across the Web in such a way that any cooperating entity can perform one or more steps in the process the same way. In a supply chain process, for example, a BPEL program might describe a business protocol that formalizes what pieces of information a product order consists of, and what exceptions may have to be handled. The BPEL program would not, however, specify how a given Web service should process a given order internally.
