Query-based access control for secure collaborative modeling using bidirectional transformations*
Gábor Bergmann, Csaba Debreceni, István Ráth, Dániel Varró · 2016
Large-scale model-driven system engineering projects are carried out collaboratively. Engineering artifacts stored in model repositories are developed in either offline (checkout-modify-commit) or online (GoogleDoc-style) scenarios. Complex systems frequently integrate models and components developed by different teams, vendors and suppliers. Thus confidentiality and integrity of design artifacts need to be protected by access control policies.
