XML Process Definition Language (XPDL)

a standard of the XPDL

XPDL Enables a Process Definition Ecosystem

XPDL is used today by more than 80 different products today to exchange process definitions. As a greater percentage part of the organization starts to use process tools for everyday work, it will become less and less reasonable to take a single-vendor strategy to process definition work. Users need to go beyond the vendor lock-in, and take a "best of breed" approach that allows the use of their favorite process technology to accomplish specific process oriented tasks, such as simulation and optimization, and future tasks that we can only dream of today.

XPDL keeps up to date with BPMN 2.0

In addition to extending the scope of its process modeling capabilities BPMN 2.0 (Business Process Modeling and Notation) introduced the ability to serialize process models and diagrams.

The new XPDL 2.2 allows existing XPDL users and supporters to continue to exploit their investment in XPDL whilst extending BPMN support to encompass the new process modeling constructs of BPMN 2.0.

XPDL is the Serialization Format for BPMN

BPMN (Business Process Modeling Notation) is a visual process notation standard from the OMG, endorsed by WfMC, and broadly adopted across the industry. Up to and including version 1.2 of the BPMN standard defined only the look of how the process definition is displayed on the screen. How you store and interchange those process definitions was outside the scope of the standard, and this is where XPDL comes in. XPDL provides a file format that supports every aspect of the BPMN process definition notation including graphical descriptions of the diagram, as well as executable properties used at run time. With XPDL, a product can write out a process definition with full fidelity, and another product can read it in and reproduce the same diagram that was sent.
