These XACML policies are then translated in FACPL, a policy language with a formal semantics, and the resulting policies are evaluated by means of a Java-based software tool.}, keywords = {Security, Model-driven development, Web engineering - Proceedings of 14th International Conference on Formal Engineering Methods (ICFEM)} }
