This kind of hurts my brain...

I have a very hard time parsing this into something meaningful. E.g.,
one specifies an instance type name on an EClass or EDataType to wrap
and existing (hand written) Java interface/class. So this is not used to
create interfaces... And "@generated not" is used to modified the
generated code of a model, not to extend it.

Embedded in what?

"concrete" meaning what?

All references are accomplished using URIs. You can use a URI to refer
to something in a jar.

Again, hard to parse. What's a "genmodel factory"?

It's really hard to figure out what your problem is exactly...

How are instances of this non-EMF business model serialized/stored? How
can you access them to load them into memory?

It seems to me you'll need to make your business model look like an EMF
model so you can use an EReference to refer to instances of them, but
without knowing how you deal with loading instances of the hand written
model, it's hard to give advice.
Currently, there is no implementation for persist the non-EMF instances.
My EMF Model is serialized by XMI, so it would be the best to use the same here.
I only have a jar with the non-emf classes.
Would it be possible to discuss my problem via skype. So I have the possibility to share my screen and show you an usecase.

Sebastian,
Providing personalized free help via skype does not scale to the large
EMF community. It might be possible to convert instances of your hand
written implementation classes to a String and resurrect them from that
string; in that case you can wrap the class in an EDataType and do that
conversion in the factory.
