Hello there!

I have a transformation where I use my own meta-model as a source. And as for the target models, I need to use two meta-models which are -indirectly- related together.

How could I achieve this? Any help will be appreciated.

Thanks.

Hi Emre,

Actually you do not need to do anything special in order to achieve that. Just create objects from desired metamodels. For example:

modeltype UML uses "http://www.eclipse.org/uml2/4.0.0/UML";
modeltype Ecore uses "http://www.eclipse.org/emf/2002/Ecore";

transformation NewTransformation(in src : UML, out dst : UML);

main() {
	object EClass {
		name := "ECore class"
	};
	object Class {
		name := "UML class"
	}
}

Type of transformation parameters' 'dst' (which is 'UML') is used as a hint on file extension to be used for output file. For the transformation above output file 'NewTransformation.uml' has the following content:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="20110701" xmlns:xmi="http://www.omg.org/spec/XMI/20110701" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:uml="http://www.eclipse.org/uml2/4.0.0/UML">
  <ecore:EClass xmi:id="_5XiVUMbtEeKBSPmarAtVhQ" name="ECore class"/>
  <uml:Class xmi:id="_5XiVUcbtEeKBSPmarAtVhQ" name="UML class"/>
</xmi:XMI>

Regards,
Sergey
