Model-driven development: a metamodeling foundation

Metamodeling is an essential foundation for MDD, but there\´s little consensus on the precise form it should take and role it should play. The authors analyze the underlying motivation for MDD and then derive a concrete set of requirements that a supporting infrastructure should satisfy. They discuss why the traditional "language definition" interpretation of metamodeling isn\´t a sufficient foundation and explain how it can be extended to unlock MDD\´s full potential.
