Model evolution is often supported by writing model transformation rules in specialized languages. This presents challenges to those who are unfamiliar with model transformation languages or metamodel definitions. This poster describes research that simplifies the creation of model evolution transformations by recording and analyzing the operational behavior exhibited by end-users. Categories and Subject Descriptors D.2.2-2.6 [Software Engineering]: Design Tools and Techniques; Programming Environments; I.6.5 [Simulation and Modeling]: Model Development General Terms Algorithms, Design, Languages.
