Hi! I'm trying to build an GMF-based editor for an UML profile defined in a previous work in my laboratory. The first approach I'm using to build the domain model is to extend by inheritance the elements the uml.ecore I'd found in mdt-uml2-Update-4.1.0M4.zip in an EMF project.

The genmodel is created without complains, but when I generated the model code several errors (about to 200) appears because of unimplemented methods of the UML elements (such as Association.getOwnedEnd(String,Type) and Dependency.getClient(String)).

I think that to implement each of this methods "by hand" will be a really time-consuming activity so I'm asking:
- Is there some place or resource that I can use that already have those methods implemented? (Since they are methods relative to the UML.ecore I think someone should have implemented and used they already.)
- Or, at least, is there a better way to implement this profile in a way I can use it as the *.ecore of the domain model of the GMF-based editor I'll build?

Thank you in advance. Wink

UML2's is generated with its own extended GenModel; anything that
extends it will also have to use UML2's extended GenModel. I'm not sure
how you'd do that if you're not expressing your extension in UML2
directly. Best to ask on the UML2 forum, where they're no doubt explain
that extending UML2 is a bad idea and that instead you should use
profiles to decorate/annotate it.

Thank you, Ed! I'll try the UML2 forum you suggested. Quick question: Do you know if the annotated metamodel will be represented in an Ecore file I can use in the GMF project?

Ricardo,

In UML2, profiles are essentially just an Ecore model that you can use
to associate additional information with the UML2 instances themselves.
That profile data is stored as part of the serialized UML. Building a
UI for UML2 is a very hard problem. It's hard to imagine you'd not be
better of trying specialize what Papyrus is already doing...
