I need to extend the UML metamodel in a purely additive manner: I just
need to subclass a few metaclasses to provide features that UML itself
does not have. I considered the profiles and stereotypes route, but it
is just too limited for my needs (because I need to create new
associations between metaclasses, and all that stereotypes let me do is
to add properties with primitive types - is that correct?).

However, after going the heavyweight route, I realized that even if I
was able to add elements of my new metaclasses to a UML model and
persist it, I would not be able to load the model as those elements
would not be understood when loading the resource. I guess that should
have been obvious were I a bit more knowledgeable about UML.

So now I am stuck. Is there a way of doing what I want so that:

a) I don't have to re-implement UML and can basically extend the UML2
API and implementation

b) models created with my metamodel can be read by any tools that can
read UML2 UML models

Thanks,

Rafael
