Abstract
Despite the fact that model composition paradigm becomes very important and most commonly used, the support for their cooperation has not reached its full strength, especially in managing composition conflicts, because it’s often divided between and confused with other model composition features. This makes handling and dealing with these conflicts a crucial activity in the composition process. Models need to be put under version control in order to manage the probable conflicts, facilitate collaboration and control change. Therefore, a solution for detecting and resolving conflicts is needed. In this paper, we present a composition conflict resolver presented in the form of a repository that helps manage composition conflicts and analyse the model and operations performed on it.
