Weaving Executability into Object-Oriented Meta-Languages

In: Proceedings of MODELS/UML'2005, edited by L. Briand, S. Kent. Springer, Montego Bay, Jamaica, pages 264-278.

Nowadays, object-oriented meta-languages such as MOF (Meta- Object Facility) are increasingly used to specify domain-specific languages in the model-driven engineering community. However, these meta-languages focus on structural specifications and have no built-in support for specifications of operational semantics. In this paper we explore the idea of using aspectoriented modeling to add precise action specifications with static type checking and genericity at the meta level, and examine related issues and possible solutions. We believe that such a combination would bring significant benefits to the community, such as the specification, simulation and testing of operational semantics of metamodels. We present requirements for such statically-typed meta-languages and rationales for the aforementioned benefits.
