jcore files

The RTC code generation tools rely on Ecore Annotations to annotate the Ecore model describing your meta-data.

The Jcore file makes it easier to edit those annotations:

Use the Ecore file to edit the Ecore model.
Use the Jcore file to edit the extra Jazz meta-data.

Each time you edit either the Ecore or the Jcore make sure you synchronize both models.

This will automatically update the annotations in the Ecore model and updates the Jcore model with the new Ecore modifications.

After finishing with the updates, you can safely delete the Jcore file.

When you double click an element in the Jcore model, the Eclipse property editor will show you the properties that you can edit.

How can I edit the jcore-files? Are there also genmodel files somewhere?

Thanks again,

You need the jazz codegen tools.
BTW, you should also probably ask these question in the jazz foundation forums.
