how to make instance model from ecore file

I have an ecore metamodel called owl.ecore, and I want to create models where classes belong to the metamodelEcore file

Wafaa,

To do this dynamically, you can use Create Dynamic Instance from an
EClass' context menu. Otherwise, follow some of the basic tutorials on
the EMF documentation page.

Hello,

but what is the purpose of creating a Dynamic Instance of an EClass, instead of generating code from the model?

Thank you,
Daniel

Hi

Completely different concepts.

Code generation gives you a Java implementation of the metamodel. You
edit the *.ecore metamodel with the Ecore Model editor.

A dynamic instance gives you a model conforming to the metamodel. You
edit the *.xmi model with the Reflective Ecore Model Editor, or *.xxxx
model in a nested Eclipse after generating an XXXX editor from your
XXXX.ecore metamodel.
