Hi,
I have used EMF Compare to compare 2 models comforming to a custom metamodel.
I generated and saved the Diff model to an .xmi file.
Currently, I am working on how to use the Diff Model within ATL to transform the differences to another model.
The problem is that I can't figure out how to access the properties of the element ( defined in my custom metamodel) being changed. I could access the kind of change like this :

diffModel.kind

but I cannot access the properties of the element which has been changed.
thanks for your help.

Hi,

You can find the Compare metamodel by importing the org.eclipse.emf.compare plugin into your workspace. Use the "File > Import..." menu, select "Plug-in Development > Plug-ins and fragments" in the popup, click "Next >" then filter on "org.eclipse.emf.compare". Add it to the right list and click "Finish". The metamodel is located in org.eclipse.emf.compare/model/compare.ecore. Looking at it should let you know how to access the elements you need.
