7. PROBLEM
• Each environment provides its own:
• Model definition (UML, Ecore, DSL, etc.)
• Instance repository technology and access mechanisms (DB, XML
Files, etc.)
• Model instances are tied to particular combinations of models and
generation tools
• If these combinations are to be changed, the data associated to the
model instances is at risk of being lost
