New journal publication on real-time collaborative modeling coming soon

Our paper, co-authored with Eugene Syriani on Real-time Collaborative Multi-Level Modeling by Conflict-Free Replicated Data Types has been suggested for publication with minor changes in the International Journal on Software and Systems Modeling (SoSyM). Pre-print available on arXiv.

Abstract. The need for real-time collaborative solutions in model-driven engineering has been increasing over the past years. Conflict-free replicated data types (CRDT) provide scalable and robust replication mechanisms that align well with the requirements of real-time collaborative environments. In this paper, we propose a real-time collaborative multi-level modeling framework to support advanced modeling scenarios, built on a collection of custom CRDTs, specifically tailored for the needs of modeling environments. We demonstrate the benefits of the framework through an illustrative modeling case and compare it with other state-of-the-art modeling frameworks.
