Putting Concern-Oriented Modeling into Practice

Providing a methodological support for designing software, separation of concerns particularly suits the emerging model paradigm. This paper elaborates on concern-oriented modeling, an approach in which the organization of models and meta-models is based on preoccupations. After a description of an annotation-based framework for modeling concerns, this paper focuses on related model transformation issues. The last part of the paper introduces and illustrates a design pattern for model merging in the context of concern-oriented modeling
