Hi, pals! I'm a rookie in Eclipse Modeling Framework and GMF and I'm in a project to build an ontology editor based in an UML profile. As a newcomer, I posted in the Newcomer Forum this question:

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


Ed Merks replied me and suggested to post the question in this forum. Also, he said that extending UML.ecore could be a bad idea and that a better way to build my metamodel is modeling the profile in Eclipse and using it to annotate the metamodel. So I'm asking now if it's possible to create this profile and annotated metamodel in a way that I can use it for the GMF project of my editor? (it will result in an ecore file?)

I'm attaching the UML fragment I have special interest in the defined profile.

Thank you for all the attention!

Hi

It's far from clear to me what you are doing, but from the errors it
would appear that you are re-implementing UML, which as you have
observed may involve rather a lot of work.

I would expect you just to reuse UML, so I suggest following a few of
the Papyrus tutorials to get a hang of the normal way of doing things.

Regards

Ed Willink

Ricardo,

You may find the following article helpful (in case you haven't seen it
already):

Thank you! I'll give it a try!
