Epsilon Flock: a model migration language
Model-driven engineering introduces additional challenges for controlling and managing software evolution. Today, tools exist for generating model editors and for managing models with transformation, validation, merging and weaving. There is limited support, however, for model migrationa development activity in which instance models are updated in response to metamodel evolution. In this paper, we propose conservative copya style of model transformation that we believe is well-suited to model migrationand Epsilon Flocka compact model-to-model transformation language tailored for model migration. The proposed structures are evaluated by comparing the conciseness of model migration strategies written in different styles of transformation language, using several examples of evolution taken from UML and the graphical modelling framework.
