In this project, we present a novel framework, called CoMPers, to manage conflicts for collaborative modeling. CoMPers is an extensible framework to provide proper support for configurable conflict management in personalized collaborative modeling. The CoMPers framework consists of a centralized Collaboration Server as well as several Clients that are connected to the Server. In our prototype implementation, we extended the Ecore-GLSP editor, which is part of the EMF.cloud project, and integrated into the Eclipse Theia IDE to provide a web-based version of the popular Ecore tools.
