Hi,
how can I store model instances of ecore models?
To be more specific: I wonder how I would store an UML object diagram (runtime-instances), that is typed over a given UML class diagram.
The class hierarchy would look like this:
M3: Ecore model defined in an .ecore file
M2: UML model defined in an .ecore file
M1: Domain model defined in an .uml file
M0: Instance model defined in an ??? file
In other words: I want to create dynamic instances of UML like it can be done in Ecore and store it into a file.
Regards,
Simon

EMF has support for the Ecore model and creating instances that conform
to an Ecore model. Any other model, such as UML2, must provide a way to
create instances based on semantics that only the model implementer can
possibly know.
