[gme-users] GME meta-metamodel

[Matthew J. Emerson]

Hello Olivier.

Currently I'm working toward incorporating MOF v1.4 into GME.  There is
a link on the GME Contributions page on the ISIS website where my work
is available, but it seems that it hasn't been updated with my most
current work.  I'll send you all my most current stuff in a separate
email so that you can play with it.

I'll attempt to answer your question too, although others know better
than I.  I think that the adoption of GME's UML/OCL meta-metamodel
predates the adoption of MOF as the OMG's standard meta-metamodel.
Also, although MOF offers some advantages over our UML/OCL
meta-metamodel, it's also lacking some features that we feel are
important for defining domain-specific modeling languages, such as
stateful Associations, facilities for multi-aspect modeling, and a
standard way to specify the concrete syntax of models.

Hi !

I'm a french student and GME user. I'd like to know why GME's
meta-metamodel is
based on UML class diagram and FCOs. It could be based on MOF. The
papers and
overviews of GME don't explain this choice.
Sincerely, Olivier.
