[gme-users] RE: ESML integration questions

[Aditya Agrawal]

Dear Akos,

The MetaGME2000 to MetaGME is the classic example of this case, where
the paradigm and its name changed. This is the case for which the
technique I mentioned was created.

In case of the metamodel containing libraries, it is easier as the new
metamodel is a superset and thus it has all the types of the old
metamodel. I have my self performed the steps I mentioned and they
worked.

Actually the most interesting part is that you can attach old models to
a new project as a library. We use this feature in GReAT all the time.

Thanks,
Adi

Vow! You are not even supposed to open mga files with a modified
paradigm, let alone a new "super-paradigm". I am impressed if
this works. The "official" method would be of course xml import
export. I would be interested to know whether that works though,
since I have not tried this myself.
