In complement to MDR and ModFact repositories, BasicMTL can now use EMF as a repository.

As metamodel, you can use either Ecore or your our own metamodel. and thus use the availbale editors like EMF editors or Omondo editors.

This greatly increase the integration within eclipse and helps to build a modeling environment with transformation.

Notice that the use of one of this repository doesn't exclude the others. You can create a transformation that uses several of them.
Ex: create a transformation that mixes Rose format(supported by EMF) to XMI 1.2 (supported by MDR)

Please look in the latest build for this support (it will be soon added in the next BasicMTL release)
