Heterogeneous Models Matching for Consistency Management

This work is situated in the context of the application of Model Driven Engineering to complex systems viewbased modelling. In fact, view-based models called also partial models are manipulated by different actors (designers), and are thus generally heterogeneous, that is, described with different DSLs (Domain Specific Languages). Instead of building a single global model, which is not realistic, we propose to organize the different partial models as a network of related models, which provides a global view of the system through a correspondence model. As models are modelled separately by different designers, they also evolve separately that induces a problem of consistency. To solve it, we propose a semi-automatic process based on the correspondence model allowing detecting changes, calculating their impacts, and proposing modifications to maintain the consistency among them. The approach is supported by a tool chain and illustrated by the example of a Bug Tracking System. Keywords—Heterogeneous models, correspondence model, change processing, consistency.
