Automatic Co-evolution of Models Using Traceability

Model Driven Engineering allows models to be considered as data and then used as first class entities in dedicated transformations languages. As a result, recurring problems linked to software production are emerging in this new development context. One such problem is to maintain an inter-model consistency during execution of a process based on models and model transformations. When some related models must co-evolve, what appends when different transformations are applied separately on each of these models? To prevent this, we assume that one of these models is the master model and we propose an automatic co-evolution of the other models based on the traceability of the main transformation. So the contribution of this paper is a conceptual framework where the necessary transformations of repercussion can be easily deployed.
