Hey all,

i've to maintain an Ecore meta-model, with was initially created with a
lot of packages regarding to structural aspects. But it is very
cumbersome to have all these different Factorys, Packages and
Litetals... my question is: Is there a built-in possibility to flatten
the Ecore structure like it is done by the UML2 meta-model?

I'm posting explicitly here, because you guys have already done it.

Thanks a lot
Timothy

Timothy,

There is a utility in UML2, the package merger, which we use to accomplish
this. In order to use it, though, you would need to use UML as the source of
your model instead of using Ecore directly, as there is no support for this
in EMF/Ecore.

If you take a look the source model for UML2, you'll see how the model needs
to be structured. Basically, you create an empty UML package that merges the
packages who content you want it to contain. Then, before you load/reload
your EMF model, you run the package merge utility (either progammatically or
via the sample UML editor).

Kenn,

that sounds promising and in fact, my source model is an UML model, so i
will try the package merger... thanks so far.
