I never claimed EMF was a language.  I claim Ecore is a language.

So what you see is how reality is defined?  An Ecore Tools graphical 
class diagram representation looks pretty much exactly like a UML class 
diagram representation, so the premise of you argument appears to be 
entirely false.

Where do you come up with these assertions?  It's like you are the 
arbiter of reality...

And that's not true of EMOF?

Ecore is isomorphic to EMOF which is just as well defined at the OMG as 
UML.  In fact, it is used to define UML.   I.e., its the underlying 
common sense of a great many other OMG specifications, including itself 
no less.

In any case, how this kind of discussion helps clarify anything for 
anyone is beyond me.  It's like you're arguing that people shouldn't use 
BPEL, XML Schema, Ecore, DSLs, or anything other than UML for all 
things.  I doubt many people will buy into that.
