[news.eclipse.tools.emf] Re: How is EDataType modeled to relate to its i

[Rich Kulp <richkulp@xxxxxxxxxxxxxxxxxx>]

Hi,

We really don't talk about meta meta models. It is far too confusing and 
it really doesn't help to make things clearer.

In EMF there is the model, and the instances. That's basically it. The 
model is the EClasses and EDataTypes and their settings. The instances 
are EObjects and java objects. The EClasses describe the EObjects and 
EDataTypes describe the java classes. That's it. Very simple.
