[Since the QVTr Editor uses the Model Registry, the meta-models may be defined using EMOF or Ecore regardless of their file extension. The meta-model may even use a non-XML form if a suitable to-Ecore translator has been registered.]
[The QVTrelation Nature must be added for the QVTr problem markers to be maintained.]
[The Model Registry Nature must be added for Model Registry Property Pages to be used.]
In the Property Page for the Model Name Accessor, invoke New...
Enter MM1, and use Browse Workspace... to locate MetaModelProject/model/meta-model1.xml.
Hit OK to complete the binding.
Repeat for MM2, using Browse Registered Packages... to locate http://meta-model2.
Finally hit OK to complete the registrations.
[If your meta-models use a non-XML format, you should select that format in the serialization combo.]
[If the required bindings for MM1 and MM2 vary between project files, define the bindings for each file rather than for the project. If the bindings are common to all files in a folder, define the bindings for the folder rather than each file.]
You may double click my/file.qvtr or a problem marker to open the editor.
