Version Management of BPEL Processes in SOA

Version management of WS-BPEL (Business Process Execution Language, BPEL) processes in SOA is not supported in a consistent way. Therefore, in this paper we propose specific extensions for BPEL to support versioning of processes and partner links. We introduce new activities and extends existing activities, including partner links, invoke, receive, import, and on-message activities. We propose version-related extensions to variables and introduces version handlers. The proposed extensions represent a complete solution for process-level and scope-level versioning at development, deployment, and run-time.
