Concern-Oriented Model-Driven Development Framework

Developing complex software systems which involve a lot of different non-orthogonal concerns requires considerable effort. This situation can be further exacerbated by tangled and scattered concerns found across the system. In order to reduce this sort of complexity, we need to employ a software development framework that facilitates the separation of different concerns. The framework should be able to direct the process of identification, modularization and specification of concerns into autonomous parts and eventually (re)compose them to yield a complete system. In this paper, we propose a software development framework which integrates the concept of a concern-oriented approach with model-driven development. This framework promotes separation of concerns both horizontal (separating concerns based on subject matters) and vertical (separating concerns based on level of abstraction).
