Import of ecore [message #1066676]

Hi,

I'm wondering how the import with Emfatic is working. As an example:

Ecore 1:

@namespace(
	uri="/org.model.variability/model/pld.ecore",
	prefix="p")

package pld;

@gmf.diagram(onefile="true", diagram.extension="pld", model.extension="pld")
class PL{

  	unsettable attr EString name = "PL";
}
....

Ecore 2:

@namespace(
	uri="/org.model.variability.hw/model/hw.ecore",
	prefix="p")

package hw;

import "platform:/resource/org.model.variability/model/pld.ecore";

In my second emf file, I imported the ecore of the first emf file. When I generate now an GMF Editor out of my second emf file, will the class PL used as diagram? In the metamodel, this class is used from both editors.. How is it possible to realise this?

Btw., what is the meaning of "prefix"?

Hi Phil,

Eugenia currently only supports self-contained Ecore metamodels. Could you please file an enhancement request so that we can investigate how metamodels that span across several files can be supported?

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=epsilon

"prefix" is used in the XMI serialisation process to distinguish between elements conforming to classes from different metamodels.

Cheers,
Dimitris

Thx for the answer, the request is now online: https://bugs.eclipse.org/bugs/show_bug.cgi?id=412290

So you mean that the import statement doesn't work for Eugenia right now?
Is there maybe a quick workaround for this? Generating the ecore is possible, so I can maybe use it then as starting point?

Cheers,
Phil
