Abstract. Large-scale software projects are often faced with the challenge of enabling the high degree of collaborative and concurrent development required to meet the aggressive delivery schedules while still maintaining a high standard of system correctness and safety. While Model-Driven Engineering (MDE) can be eective in accelerating development, traditional approaches to addressing the above challenges are designed for code, and are not directly applicable to models. In this paper, we propose a novel approach to addressing the problem of model-based collaborative development using property-based techniques. We illustrate our proposals and outline the challenges to realizing them.
