WS-BPEL extension for compliance fragments (BPEL4CFrags), Version 1.0

Abstract

The Web Services Business Process Execution Language, version 2.0 (WS-BPEL 2.0 or BPEL for brevity) introduces a model for business processes based on Web services. A BPEL process orchestrates interactions among different Web services. The language comprises features required to describe complex control flows, including error handling and compensation behaviour. BPEL for Compliance Fragments (BPEL4CFrags) enables the specification of compliance fragments providing a reusable solution for implementing and meeting compliance requirements. The compliance fragments are not necessarily executable. Providing process modeling support at design time requires the completion of not directly executable compliance fragments, because compliance fragments contain several degrees of freedom, into already existing executable BPEL processes. Moreover, assistance for creation of executable BPEL processes from scratch during IT refinement has to be provided.
