5. BPMN 2.0
Business Process Modeling Notation
 For business analysts
 To represent business processes
 Typical examples:
Absence request
Booking a plane ticket
Loan process

6. BPMN 2.0
Notion of participants and messages
client
server

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

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

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

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

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.

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

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

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

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)

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

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 ?
