Hi,
I have another problem with references between models.
I have an element Instance in metamodel which has a reference (type) to
the Ecore element EModelElement.
When I create a model, and load UML.ecore as resource, I can select in
reference type the type of the element that I want to represente.
An example:
Instance - type = Class->EncapsuledClassifer,BehavioredClassifer
something like this:
<instance name="clase">
<type xsi:type="ecore:EClass" href="UML.ecore#//Class"/>
</instance>
I am doing a transformation and I want to compare the value of
instance.type (which is Class->EncapsuledClassifer,BehavioredClassifer)
with UML!Class but I don't know how do this.

That's why it is important to have allowInterModelReferences switched
on, only than the transformation will follow references to other model,
like your UML.ecore.

So CatalogMM is youre M2 and ecore is your M1.

Indeed it is.

This is what you wanted, or better what you can get, the name of the
EClass. And it is what instance.type.name should return.
This would be your discriminator, the name of the EClass in
instance.type Generalization/Class .... what ever name the EClass has.

This is quite odd, and unexpected, based on our assumptions.

Finally I have solved it.
The solution has been to change the type reference (to the EModelElement)
that I had put to Instance element and reference the EObject element.
It should have worked with EModelElement reference but ATL results weren't
as we thought.
That's all, thanks.
