In this paper we model and test a Dynamic Ontology based Role-Based Access Control (DO-RBAC) model. This dynamic RBAC model was originally written in Prolog, and applied to and tested on multiple hospital databases. Our work demonstrates that the mapping of Prolog facts, rules and context constraints imposed on them into ontological modelling constructs of DO-RBAC is feasible, and that the DO-RBAC model can be extended if new roles are added to the RBAC. Our principle is to (a) model Prolog facts and rules within the DO-RBAC schema using OWL modelling constructs, and (b) reason upon the DO-RBAC schema using SWRL rules mapped from dynamic RBAC context constraints. DO-RBAC serves as an input to a generic authorisation engine which can control access in various contexts of pervasive computing environments.
