The XML Process Definition Language (XPDL) is a standard language that is used to represent workflow and business processes. It is generally used to exchange process definitions between different business processing systems. CentraSite provides an importer for XPDL files. This importer reads an XPDL 2.x file and adds the process that it defines to the registry as a Process object. It stores the XPDL file itself in CentraSite's repository.
