Hi,

I would like in a .ecore file create classes which inherit or use some EObject of the EMF meta model.
For example I would like to create a class MyEclass which inherit EClass.

Hi,
click on the menue "Sample Ecore Editor" => Load Ressource and select
the Ecore you want to use. Then you can use any element, like it was
part of you model. When you create the model later on, make sure you
uncheck the referenced model from creation and only use it as a reference.
Cheers
Jonas

Hi Jérémie,

Note that is is generally recommended *not* to extend Ecore! Compare,
e.g., http://old.nabble.com/EMF-metamodel-reuse-td21827507.html

oki,

So I will try to use EMF classes with no inherit, only aggregations and compositions. hope I still will be able to do what I want with this method.
But where can I find the Ecore.ecore file to use it in my meta-model?

I think it's best to import the org.eclipse.emf.ecore plugin into your
workspace and load it like Jonas eyplained.

Eike,

It's also fine to use Load Resource -> Browse Registered Packages and
load the Development Time version as Jonas alluded to.
