 - BPEL (Business Process Execution Language) for Web services is an XML-based
language designed to enable task-sharing for a distributed
computing or grid computing environment - even across
multiple organizations - using a combination of Web services.
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.
