The Workflow Management Coalition (WfMC) announced the release of the Workflow Standard – XML Process Definition Language – XPDL 1.0. Together with other WfMC standards, XPDL provides a framework for implementing business process management and workflow engines, and for designing, analyzing, and exchanging business processes. XPDL is the culmination of a 15-month effort by multiple vendors and users to provide a standard that satisfies the needs of diverse organizations. One of the key elements of the XPDL is its extensibility to handle information used by a variety of different tools. Based upon a limited number of entities that describe a workflow process definition (the “Minimum Meta Model”), XPDL supports a number of differing approaches. A process defined in XPDL (a set of XML statements) can be imported into any workflow engine that supports XPDL. The related objects and attributes (data associated with the process) are now also included in the XPDL process definition. The XPDL process definition can be generated by workflow modeling and simulation tools, or can be manually coded, or can be exported from another XPDL-compliant workflow engine. Described as Document WfMC-TC-1025, it may be downloaded at www.wfmc.org/standards/docs.htm
