One last thing before you get started: While working on your model, save and validate it regularly (Edit -> Validate). This will help you find potential problems with your model while you're still able to fix them easily.

a Metamodel
It is entirely possible to model your metamodel graphically. Since the graphical editing of EMF models has changed in the last Eclipse version, this is only mentioned here as alternative route. To generation an Ecore Diagram proceed as mentioned before. Now, right-click on your model file and select Initialize Ecore Diagram... from the context menu. Create a new Design -> Entities representation and select your package in the following step. You can now create and link all the model elements mentioned in the section before. The changes will be integrated in your Ecore model automatically. However, as mentioned before you don't need to edit your model graphically. This procedure is only described here for the sake of completeness.
Inspecting a Model
Nevertheless you may want to inspect your model graphically. Therefore you installed EcoreViz of the OpenKieler suite. While working on your model, you may right-click on your ecore file and select Vizualize Ecore Model. A new Klighd view will open and display your metamodel. Woha!
