Hi all,
what is the status of work on mappings between the Intalio metamodel
(http://www.eclipse.org/bpmn/model/index.php) and the OMG one, as used for
example in http://wiki.eclipse.org/index.php/GMF_Tutorial_BPMN)?

Is a unidirectional transformation complete (perhaps one in each
direction)? Does such transformations support change propagation?
Perhaps someone has defined one bidirectional transformation?

Any pointers or just developer names are welcome.

Kind regards,

The metamodel Intalio contributed is the metamodel of the BPMN modeler.
It is not _the_ Intalio metamodel. At Intalio, we refer to it as the
schema we use for reference just because it works.

The OMG metamodel you reference over there:
http://wiki.eclipse.org/index.php/GMF_Tutorial_BPMN#Developi ng_the_Domain_Model
was developed by Rich Gronback for the purpose of developing a domain
model from the spec. So he did pretty much the same exercise we did when
it came to generating the metamodel.

Both those models were designed when BPMN 1.0 was available, and the OMG
had no metamodel available for BPMN at the time.

Keep in mind that BPMN stands for Business Process Modeling _Notation_.
The BPMN modeler just gives users the power to apply the notation. It's
not pushing for a reference metamodel of BPMN.
Intalio, and Ismael through a blog post, pushed for the metamodel we use
because it works, nothing more.

There are several initiatives taking place at Eclipse that will interest
you to that regard I think. First, check out the BPMN2 MDT component.
They will implement a reference implementation of the BPMN2 metamodel.

Also look at the STP-IM and the JWT projects. Both can help you with
transforming the BPMN model.

My name is Antoine Toulme. You can discuss with me here. I am the lead
for this sub-project.
