using UML metaclasses within the extended metamodel [message #476717]

Hi,

I build a metamodel using the middleweight extension mechanism. I want
to define a metaclass that has nothing more than the Class metaclass,
except that I want to change its name from Class to Resource. could you
help me how to apply that case?

Moreover, I want to create an association between a metaclass in my own
metamodel and a UML metaclass. Is it possible? If yes, how can I do that?

Regards,
Manar

Manar,

Sorry for the delayed response; James is on vacation...

Have you looked at the overview provided at
http://www.eclipse.org/modeling/mdt/uml2/docs/presentations/ EclipseCon2007_LongTalk.html?
It should be a simple matter of creating a metamodel that contains your
'Resource' metaclass with a generalization to the 'Class' metaclass from the
UML metamodel and with associations to the desired other metclasses in the
metamodel...

Kenn,

I looked at this overview carefully. But, I want to do that using the
middleweight extension not by using the heavyweight mechanism. I want to
create an association between a metaclass in my own metamodel and a UML
metaclass. Is it possible? If yes, how can I do that?

Thanks in advance,
Manar

Manar,

I think you just use Load Resource... to load the UML resource with the
model you want to reference and then the classes in it will be available
to create associations in your model.
