Brief

Businesses implementing Web Services require a model for describing how individual Web Services can be interconnected to create complex, reliable, and dependable business solutions. Business Process Execution Language for Web Services (BPEL4WS) provides an XML-based process definition and execution language that enables the description of rich business processes capable of consuming and providing Web services in a reliable and dependable manner. BPEL4WS enables portability and interoperability by defining constructs to implement executable business processes and message exchange protocols, thereby supporting both executable and abstract business processes.

The BPEL4WS Specification extends and subsumes previous specifications that were originally published individually as Microsoft XLANG and IBM WSFL. BPEL4WS represents a convergence of the structured process orientation of XLANG with the graph-oriented approach of WSFL, eliminating an old dichotomy in the process modeling world. As a result, BPEL4WS provides a seamless foundation for a rich variety of business process modeling styles.

The original BPEL4WS 1.0 specification was published in August 2002 by Microsoft, IBM and BEA. In May 2003, Microsoft, IBM, BEA, SAP and Siebel released version 1.1 of the BPEL4WS specification. The BPEL4WS 1.1 specification provides a modular structure, enabling core process modeling concepts to be extended to support both executable models and business protocols.

The BPEL4WS 1.1 specification was jointly submitted to OASIS under royalty free (RF) and other reasonable and non-discriminatory terms. The OASIS WSBPEL Technical Committee was established to continue working on the BPEL4WS 1.1 specification within the OASIS TC Process.
