  1. 1. XPDL 2.0 Tutorial Mike MarinWfMC Technical Committee Vice Chairman (Americas) Software Architect, FileNet Corporation
  2. 2. Agenda• XPDL Definition• Process Interchange• BPMN Definition• XPDL 2.0 Description• Future 2
  3. 3. XPDL Definition• XML Process Definition Language (XPDL)• A modeling language for Process Definition• A Process Definition Meta-model• WfMC Reference Model Interface 1 – Process definition• Goals • Process Definition Model interchange between tool 3
  4. 4. The Process Definition• Activity Network – Nodes & Transitions • Sequential, Parallele, Conditional, and Message paths• Activity Definitions • Arbitrarily complex graphs • Resource Requirement • Sequential Activities • Work Assignment • Parallel Activities • Applications and Services • Loops / Cycles • Conditional Paths• Data Definitions 4
  5. 5. Process Definition Interchange• Common meta-model • Allow tools to exchange models• Type of tools • Simulation tools • Monitoring tools • Execution tools • Modelling tools • Repository tools 5
  6. 6. Meta-Model BPMN XPDL Framew ork Common Objects, Attributes, Semantics, and Usage Vendor Internal Vendor Internal Vendor Internal Import / Export Layer Import / Export Layer Import / Export Layer XPDL Simulation Engine Execution Engine Monitoring Engine6
  7. 7. An Example of Standards Utilization• Today more than 24 products support XPDL • See for details Process Modeling Analysis, Sketchpad Reporting and BPMN Work Monitoring Process Processing XPDL Designer XPDL Simulation XPDL Controller Animator Engine XML Log Events Process Analytics Execution OLAP Performance Management 7
  8. 8. XPDL 2.0 Purpose• A persistent format for BPMN • XPDL provides an XML file format • BPMN provides a graphical notation• Back compatible with XPDL 1.0• XPDL and BPMN address the same modeling space 8
  9. 9. BPMN• Graphical Business Notation to • Describe processes • Describe interaction between processes• Business Process Modeling notation (BPMN) • Object Management Group (OMG) • Business Process Management Initiative (BPMI) group• Design to be used by business analysts 9
  10. 10. Core Set of Diagram Elements The core set of modeling elements enable the easy development simple Business Process Diagrams that will look familiar to most Business Analysts (a flowchart diagram) 10
  11. 11. Swimlanes A Pool is a “swimlane” and a graphical container for partitioning a set of activities from other Pools, usually in the context of B2B situations. A Lane is a sub-partition within a Pool and will extend the entire length of the Pool, either vertically or horizontally. 11
  12. 12. Events An Event is something that “happens” during the course of a business process. These Events affect the flow of the Process and usually have a trigger or a result. They can start, interrupt, or end the flow. 12
  13. 13. Activities An activity is work that is performed within a business process. An activity can be atomic or non-atomic (compound). The types of activities that are a part of a Process Model are: Process, Sub- Process, and Task. 13
  14. 14. Activities A Sub-Process can be in an expanded form that shows the process details of the a lower-level set of activities. 14
  15. 15. Connections•A Sequence Flow is used to show the order that activities will beperformed in a Process.•A Message Flow is used to show the flow of messages betweentwo entities that are prepared to send and receive them.•An Association is used to associate information and artifacts withflow objects. 15
  16. 16. Gateways Gateways are modeling elements that are used to control how Sequence Flows interact as they converge and diverge within a Process. If the flow does not need to be controlled, then a Gateway is not needed. 16
  17. 17. Artifacts Data Objects are not flow objects (i.e., connected through Sequence Flow), but they do provide information about how documents, data, and other objects are used and updated within a Process. Text Annotations are a mechanism for a modeler to provide additional information for the reader of a BPMN diagram. Groups provide a mechanism to visually organize activities 17
  18. 18. BPMN Example 18
  19. 19. XPDL – BPMN Marriage• BPMN • Graphical notation • No file format• XPDL • XML file format • No graphics 19
  20. 20. Sketchpad for BPMN 20
  21. 21. New Elements in XPDL 2.0 from BPMN• Pools and lanes • used to define participants and roles• Message flows • used for communication between processes• Associations and Artifacts • used to document the process definitions• Graphic information for each entity 21

  24. 24. Tool and Vendor Information• Each tool can add tool specifics • Graphical information • Extensions <xsd:element name="VendorExtension"> <xsd:complexType> <xsd:sequence> <xsd:any namespace="##other" processContents="lax"/> </xsd:sequence> <xsd:attribute name="ToolId" type="xsd:string" use="required"/> <xsd:attribute name="schemaLocation" type="xsd:anyURI" use="required"/> <xsd:attribute name="extensionDescription" type="xsd:anyURI" use="optional"/> <xsd:anyAttribute namespace="##other" processContents="lax"/> </xsd:complexType> </xsd:element> 24
  25. 25. Tool Specific Graphical Information• Each tool adds its own graphical information• Same XPDL can be displayed different by different tools Tool A Tool B Tool C XPDL 25
  26. 26. Example<Activity Id="31" Name=""> <Route GatewayType="AND" MarkerVisible="true"/> <TransitionRestrictions> <TransitionRestriction> <Join Type="AND"/> </TransitionRestriction> </TransitionRestrictions> <NodeGraphicsInfos> <NodeGraphicsInfo ToolId="ToolA" Width="41.0" Height="41.0"> <Coordinates XCoordinate="10" YCoordinate="75"/> </NodeGraphicsInfo> <NodeGraphicsInfo ToolId="ToolB" Page="1" Width="890"> <Coordinates XCoordinate="23" YCoordinate="12"/> </NodeGraphicsInfo> <NodeGraphicsInfo ToolId="ToolC" Width="25" Height="34" Shape="Round"> <Coordinates XCoordinate="1078" YCoordinate="230"/> </NodeGraphicsInfo> </NodeGraphicsInfos></Activity> 26
  27. 27. Extended Elements and Attributes• XPDL schema is extensible• Allows vendors to extend XPDL • Adds arbitrary XML in a well defined manner• Anonymous and namespace qualified extensions 27
  28. 28. Future• XPDL • WfMC will continue to maintain XPDL • Will update based on • BPMN evolution • Implementers comments• BPMN • BPMI has become part of OMG • BPMN will be further developed within OMG. 28
