BPMN 2.0

A reboot from BPMN 1.2a formal metamodelXSD and CMOF

aligned with BPEL 2.0meaning it’s executable

Use qnames and imports to segment bpmn filesAllow to define interactions between different BPMN diagrams

Using qname resolution over the id attribute

BPMN 2.0 projectStarted in 2007 by Kenn HusseyFirst contribution from Intalio end of 2009EMF model generated from the XML schema of the beta 1.30% of the shape graphics

Second major contribution from SAPMetamodel based on the final specification CMOF and XSD

2 active committersOpening a vote for a new committer from SAP this week


BPMN 2.0 project history

10

Implement a Java metamodel for BPMN 2.0 modelsBased 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


Goals of a BPMN 2.0 implementation at Eclipse

11

Introduce standard graphics for BPMN 2.0SVG-based high quality graphicsGenerated pngs of different sizesCovers 30% of the specification so far.



12

Validation frameworkUse the Eclipse Modeling Validation FrameworkUse abstract validation rules at the element levelConnection constraintsDefault flowsMisplaced constructs

Eventually validation rules can be contributed back to the next BPMN RTF.



13

The BPMN 2.0 project is not:a process modelerThe SOA BPMN modeler would be the beacon of the next BPMN 2.0 editor

an execution environmentThe metamodel is here for manipulation and validation



14

CMOF Metamodel Defines XMI exchange format

Advantages:Multi InheritanceAll references are typed - nice for programming

DisadvantagesStill low adoption of XMI as exchange formatNo samples in XMI available


Mapping the specification to its implementation

15

XML Schema Defines XML exchange format

AdvantagesWidely adopted exchange formatSamples available Easy to validate

DisadvantagesSingle Inheritance, thus a lot of redundancyAll references are untyped (Qnames), thus not nice for programming



16

We contribute a Ecore metamodel that is programmatically merged from CMOF and XSDCan read/write XMI according to CMOFCan read/write XML according to XSDProvides a really nice API to work on BPMN modelsKeeps MOF Multi Inheritance Keeps all typed referencesEMF Validation, e.g. on mandatory features and broken references

Tree editor support out-of-the box (EMF Edit)



17

Reiner’s tool for a better modelFixes plurals for methods namesMakes changes for consistency (not necessary as we reached a final model)

Validates both CMOF and XSD for consistencyCompletely automated



18

Contributions from OMG members are welcome!Pictures, examples, documentation, tutorials...

Participation to the next RTFThe BPMN 2.0 project will provide feedback to the next BPMN RTF

A validation test suite in plain english

Interest on working on intermediary modelsEventually get the ecore model to be contributed to the specification with Reiner’s tool ?


Possibilities for more collaboration
