Model Evolution : Comparative Study between Clafer and Textual UML

This paper presents a comparative study between two modeling languages; Clafer and Textual UML. In this work, we present our motivation for domain modeling, we perform a pilot study to provide preliminarily results about the differences between both modeling languages with respect to structural model evolution at the requirements stage. We conclude with lessons learnt and considerations to take into account with the experimental design for the empirical study.
