Managing director of IncQuery Labs, István Ráth published a paper with Dániel Varró, Gábor Bergmann and Csaba Debreceni from Budapest University of Technology and Economics in the Software and Systems Modeling journal.
Large-scale model-driven system engineering projects are carried out collaboratively. Engineering artefacts stored in model repositories are developed in either ofﬂine (checkout–modify–commit) or online (GoogleDocstyle) scenarios. Complex systems frequently integrate models and components developed by different teams, vendors and suppliers. Thus, conﬁdentiality and integrity of design artefacts need to be protected in accordance with access control policies. The paper focuses on a secure collaborative modelling approach.
