Hi,
I've created a metamodel and generated a model from it in EMF. As you know In EMF it is possible to create a diagram for the metamodel using the "initialize ecore diagram".
index.php/fa/40777/0/

However, I want to know how can I generate a diagram for the model instance?

Hi

This is unfortunately one of the major omissions of the Eclipse EMF-based modeling capabilities. See Bug 537739 [1].

You can develop a custom diagram editor for a specific metamodel using Sirius.

However EMF has powerful reflective/dynamic capabilities that support the Sample Reflective Ecore Model Editor display of any instance model.

When I needed such a facility for a workshop paper; see Fig 2 of [2] I therefore created a similar capability using Sirius that you can find as org.eclipse.qvtd.xml.design. However I must confess that I find it really hard to use since I have so far not devoted sufficient time to to providing the simple "Initialize Refective Ecore Diagram" action. Instead I get lost in the difficulties of declaring viewpoints and diagrams in an irregular perspective.
