Evolution des profils UML : vers une migration automatisée et une optimisation assistée des modèles

The abstract syntax of a modeling language evolves all along the life-cycle of this language with its successive versions and these evolutions can have important repercussions on the models described in this language. We study the evolutions of the abstract syntax when this syntax is defined by a UML profile. More particularly, we are interested in the UML profile evolutions impacts on the instance models and in minimizing the efforts to migrate models to a new version that has to be compliant with the new version of the profile. Indeed, the cost of a models manual migration can sometimes be higher to the cost of a complete redefining. Defining a UML profile evolutions classification according to their impacts on the instance models is the indispensable step to offer an automated migration adapted to each evolution. The objective is to reduce as much as possible the different interventions of the designer and to guide the evolution process. MOTS-CLÉS : syntaxe abstraite, évolution de profil UML, classification d’évolution, classification d’impact, migration de modèle.
