RCVDiff - a stand-alone tool for representation, calculation and visualization of model differences

In model comparison one can distinguish three major sub- problems: representation, calculation, and visualization of model di¿erences. Existing stand-alone tools for managing model di¿erences usually focus on one or sometimes two as- pects of model comparison. In this paper we discuss our stand-alone tool calledRCVDi¿, that incorporates all three aspects of model comparison. Furthermore, we comment on some issues in the process of model comparison that are not easily perceived if the three aspects of model comparison are considered independently.
