Possible to configure the xml-structure of an ecore-model instance? [message #431664] Tue, 21 July 2009 10:01 Go to next message

Originally posted by: formatzeh.gmx.de

I'm interested in if it is possible to configure the structure of the
xml which will be created when instantiating an ecore model by an
generated editor. I would have an xml structure containing classes of my
metamodel as xml structure-elements and not as attributes. Now that's
the case only for my root class of my model, containing the defined
prefix. All the other classes appear as attributes in the xml and the
roles of the references are represented as xml elements. I imagine that
only classes of the metamodel are sufficient as xml-elements and roles
names of the references don't need to appear, isn't it? Hope I expressed
myself understandable.

best regards,
Gilbert

To an extent yes.

Extended meta data annotations can be used for that.

Not sure what you mean. Have a read through this:

http://www.eclipse.org/modeling/emf/docs/overviews/XMLSchema ToEcoreMapping.pdf

The annotations it describes can be added directly to an Ecore model...
