Customizable model migration schemes for meta-model evolutions with multiplicity changes

Abstract

Modeling languages tailored to specific application domains promise to increase the productivity and quality of model-driven software development. Nevertheless due to, for example, evolving requirements, modeling languages, and their meta-models evolve which means that existing models have to be migrated accordingly. In our approach, such co-evolutions are specified as related graph transformations ensuring well-typed model migration results. Model migrations are specified by transformation rules that can be automatically deduced from given meta-model evolution rules and further customized to special needs. Up to now, meta-model constraints have not been taken into account. In this paper, we extend our approach to handle multiplicity constraints and illustrate this extension using several examples. © 2013 Springer-Verlag.
