Metamodel-driven model interpreter evolution
Jing Zhang · 2005
Domain-specific modeling (DSM) raises the level of abstraction by specifying a metamodel that is aligned to a particular problem domain. A key feature of DSM is the construction of model interpreters that synthesize the domain models into software artifacts. In the presence of new stakeholder requirements, it is possible that a metamodel undergoes numerous changes during periods of evolution (a new instance of the classic schema evolution problem). Consequently, there is a fundamental problem in keeping the model interpreters up to date with metamodel changes. This research abstract outlines the technical challenges in formalizing model interpreter implementation with the intent to facilitate interpreter evolution in terms of metamodel migration.
