Hello,
I am trying to turn two XSDs into ecore metamodels, and I succeeded in doing
this. Using EMF I can now generate an editor that creates XML instances for
the XSDs.
However, when I try to execute an ATL transformation on one XML instance, to
obtain an instance of the other model, I get the error below (My.gse is an
XML file conforming to the ecore model generated from the XSD and to the XSD
itself of course).
I defined the two ecore models created from the XSDs as metamodels, and I
consider their XML instances as the models when I run the transformation.
Do I miss a step here? Do I have to define the models as ecore files too?
How do I make sure they comply with the metamodels based on XSD?
Can somebody put me on the right track? (Yes, I can do this with XSLT,
without the ecore deviation, but I want to use the ecore stuff to build
Eclipse editors for the metamodels...)
Thank you for any help!

Some time ago, I've also worked with EMF-XSD and ATL. You can have a
look at my solution, in case it helps:

Kind regards,
