Hi,

I'm creating one metamodel by using Ecore tools, but I need to reference some ecore meta-model classes from my metamodel classes in a diagram/model. How can I do this?

thx, Milan Milanovic

Dear Mr. Merks,

I did on my ecordiag...right click and Load resource... http://www.eclipse.org/emf/2002/Ecore, however I cannot see ecore anywhere in my model or diagram? I did the same thing for my domain ecore metamodel, but also I cannot see it in Project Explorer.

Milan,

Don't they show up in the outline? You can drag and drop from the
outline and those models should be available as choices in the properties...

Dear Mr. Merks,

no, I can see only my metamodel packages, Diagram and Additional resources (emtpy) items in Outline. There is no Ecore metamodel there.

btw - I'm using latest Eclipse Modeling Galileo and JDK 1.6.

Milan,

When I use Load Resource... the new resource is added under "Additional
Resources". You're sure that's not the case?

Dear Mr Merks,

When I Load Resource... in my ecore diagram with http://www.eclipse.org/emf/2002/Ecore value, Additional Resources in Outline remains empty. When I do the same thing for my ecore metamodel in Simple EMF editor, I see ecore metamodel below my metamodel, however when I close that file and open it again, I don't see ecore metamodel anymore. In Project Explorer I cannot see ecore metamodel in both cases. I tried the same Load resource... in Outline window, but again, there is no change.

One more thing, what is corresponding class in ecore, for cmof Element? Is it EObject? Does all classes defined in ecore implicitly inherit EObject?

Milan,

I'm not sure what CMOF Element is. Ecore corresponds to EMOF not to
CMOF. All generated implementation classes implement EObject and by
defined generated interfaces extends EObject, but that's not required
and can be changed with the Root Extends Interface to be blank or
something else.
