Members of the OASIS open standards consortium will advance a specification to formally describe interoperable business processes and business interaction protocols for Web services orchestration. The new OASIS Web Services Business Process Execution Language (WSBPEL) Technical Committee will continue work on the Business Process Execution Language for Web Services (BPEL4WS) specification, an XML-based language that allows users to describe business process activities as Web services and define how they can be connected to accomplish specific tasks. BEA, IBM, Microsoft, and SAP intend to formally submit BPEL4WS version 1.1 under royalty free terms to the new OASIS Technical Committee at its first meeting on 16 May 2003. The committee is open to submissions of other in-scope contributions and will establish liaison relationships with related Web services efforts within OASIS and other standards organizations including the World Wide Web Consortium (W3C). OASIS WSBPEL Technical Committee members include Booz Allen Hamilton, BEA Systems, Commerce One, E2open, EDS, IBM, Microsoft, NEC, Novell, SAP, SeeBeyond, Sybase, Tibco Software, Vignette, Waveset, and others. Participation remains open to all organizations and individuals, and OASIS encourages both vendors of business process automation software as well as end users interested in automating and integrating their internal or external business processes to join this effort. OASIS will host an open mail list for public comment.
