Hi everybody.
I'm taking my first steps with Epsilon (EML mostly), and I'm trying to
compose Model A (from Metamodel A) and Model B (from Metamodel B) into
Model C (from Metamodel C). Two inputs, one output, three different
metamodels.
I have already defined the metamodels, the emfatic file with the
relationships between the input metamodels, and generated the
correspondent ecore model. I also created a ".modelink" indicating the
elements I want to combine (merge).
Now I'm wondering how to continue.

To launch a model merge I need the ".eml" that tells epsilon the source
(base), the aspect, and the target.
I guess I can add the ".modelink" (actually, the model with the
relationships resulting from it) as input, and according to the
relationships modeled in it make the ".eml" merge elements from A with
elements from B into C. Am I right?.

However, I'm not sure on what to do with the ".ecl" matching.
Do I have to make rules for matching elements in Model A with elements
in Model B?, or for matching elements in Model A with elements in Model
C, and then rules for matching elements in Model B with elements in
Model C?.

Which is the correct strategy to make such a composition?.
Thanks in advance.
Regards,
Juan Pedro
