Ok I think I have the wrong terminology here.|
By model I mean the ECore "meta"-model, the abstract model that describes
the rules a particular model instance must follow.
An analogy would be an XML schema, and an XML document which is written
according to the schema.
Keeping on with the analogy, I have an XML document which follows a
particular schema. Now I want to find out what the schema is (reverse
engineer it). Is there any way to work out the an ECore model from instances
