Concern management for constructing model compilers

Model-driven architecture (MDA) aims at automating soft- ware design processes. A model compiler transforms platform- independent models into platform-specific models automatically. In order to construct an effective model compiler, we need to take account of not only platform concerns but also other kinds of model transformation concerns including optimization, real-Time constraints, and deployment. However, current model compilers do not provide a mechanism for managing these multiple concerns. We propose a method for constructing an extensible model compiler based on aspect- orientation. A modeler can manage multiple concerns and extend model transformation rules by defining new aspects in the process of modeling. In this paper, an aspect-oriented modeling language called AspectM is introduced for managing modeling-level aspects.
