Hi!

I would like to compare to versions of a uml model, but there are the following issues:

1. how to ignore annotations?
The rational software modeler uses the uml2 metamodel from [1] and stores the diagrams in annotations of packages:
- package xyz
- annotation
+ diagram
+ class A
+ class B
Hence, each time I just want to compare the _model_, the diagrams are also part of the comparison.
I have seen a filter feature in the generic match engine -- can I exploit that for filtering the annotations containing the diagrams?
What would be the designated way of ignoring model elements in the comparison process?


2. Is there already an example available of how uml associations can be dealt with in EMF Compare as explained in [2]?
Or in general whether there already exists a diff engine which is better suited for uml models than the generic engine?


Cheers
Patrick
