Hi,
I am a newbie to JAF and have a question regarding versioning objects with a complex structure.

Background:
I am working in a project addressing collaborative editing of policies and these policies are modeled in EMF.
I would like to use the Jazz platform for lifecycle management of these policies (ie, of the EMF model instances). First thought is to version the XMI serialization of the respective EMF model instances.
Jazz versioning presumably operates at document level (XMI in this case)  whereas ideally we would version at level of model elements, similar in spirit to EMF Store. We could perhaps mimic model element versioning by storing sub-elements of the policy as individual XMI documents, using references in the containing policy instance to construct the policy instance upon query. But maybe this approach rapidly becomes very complicated.

Question:
Are there any references to projects which version structured objects such as deep XML documents or EMF models?

Thanks,
-chris
