Model Migration through Visual Modeling

The true value of domain-specific modeling is found not in a domain-specific modeling language (DSML) but rather in the models that are created using that DSML. Changes to a physical system can be modeled, and the resulting executable model then is a working version of the physical system. Unfortunately, if the model of the domain—or metamodel—is changed, all models that were defined using that metamodel may require maintenance to have semantics that correctly represent the existing system. This paper introduces a visual modeling environment that allows for the evolution of modeling environments using XSL stylesheets as the execution language.
