- 7. BPMN 2.0 Notion of flow for each participant Flow is modeled using boxes and arrows you can use specialized boxes (task types and events) you can deal with exceptions and errors client LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 7
- 8. BPMN 2.0 A reboot from BPMN 1.2 a formal metamodel XSD and CMOF aligned with BPEL 2.0 meaning it’s executable Use qnames and imports to segment bpmn files Allow to define interactions between different BPMN diagrams Using qname resolution over the id attribute LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 8
- 9. The Eclipse Foundation A few words about Eclipse Project management at Eclipse TLPs Subprojects Modeling Components PMCs Model Development Tools How to join Corporate-friendly UML2 BPMN2 Patches Community involvement LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 9
- 10. BPMN 2.0 project history BPMN 2.0 project Started in 2007 by Kenn Hussey First contribution from Intalio end of 2009 EMF model generated from the XML schema of the beta 1. 30% of the shape graphics Second major contribution from SAP Metamodel based on the final specification CMOF and XSD 2 active committers Opening a vote for a new committer from SAP this week LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 10
- 11. Goals of a BPMN 2.0 implementation at Eclipse Implement a Java metamodel for BPMN 2.0 models Based on EMF (Eclipse Modeling Framework) Backed by the specification artifacts (as close to the XML schema as possible) Developer-friendly (using plurals) Supporting the qname resolving mechanism LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 11
- 12. Goals of a BPMN 2.0 implementation at Eclipse Introduce standard graphics for BPMN 2.0 SVG-based high quality graphics Generated pngs of different sizes Covers 30% of the specification so far. LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 12
- 13. Goals of a BPMN 2.0 implementation at Eclipse Validation framework Use the Eclipse Modeling Validation Framework Use abstract validation rules at the element level Connection constraints Default flows Misplaced constructs Eventually validation rules can be contributed back to the next BPMN RTF.

- 14. Goals of a BPMN 2.0 implementation at Eclipse The BPMN 2.0 project is not: a process modeler The SOA BPMN modeler would be the beacon of the next BPMN 2.0 editor an execution environment The metamodel is here for manipulation and validation LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 14
- 15. Mapping the specification to its implementation CMOF Metamodel Defines XMI exchange format Advantages: Multi Inheritance All references are typed - nice for programming Disadvantages Still low adoption of XMI as exchange format No samples in XMI available LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 15
- 16. Mapping the specification to its implementation XML Schema Defines XML exchange format Advantages Widely adopted exchange format Samples available Easy to validate Disadvantages Single Inheritance, thus a lot of redundancy All references are untyped (Qnames), thus not nice for programming LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 16
- 17. Mapping the specification to its implementation We contribute a Ecore metamodel that is programmatically merged from CMOF and XSD Can read/write XMI according to CMOF Can read/write XML according to XSD Provides a really nice API to work on BPMN models Keeps MOF Multi Inheritance Keeps all typed references EMF Validation, e.g. on mandatory features and broken references Tree editor support out-of-the box (EMF Edit) LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 17
- 18. Mapping the specification to its implementation Reiner’s tool for a better model Fixes plurals for methods names Makes changes for consistency (not necessary as we reached a final model) Validates both CMOF and XSD for consistency Completely automated LICENSED UNDER EPL 1.0 OMG/Eclipse Symposium, June 22nd 2010 © Intalio, Inc. 18
- 19. Possibilities for more collaboration Contributions from OMG members are welcome! Pictures, examples, documentation, tutorials... Participation to the next RTF The BPMN 2.0 project will provide feedback to the next BPMN RTF A validation test suite in plain english Interest on working on intermediary models Eventually get the ecore model to be contributed to the specification with Reiner’s tool ?
