In this project, we explored the motivations for, and development of, a rule-based policy management system that can be deployed in the open and distributed milieu of the World Wide Web. We demonstrated the necessary features of such a system in creating a “Policy Aware” infrastructure for the Web, and argued for the necessity of such infrastructure. We then showed how the integration of a Semantic Web rules language (N3) with a theorem prover designed for the Web (Cwm) made it possible to use the Hypertext Transport Protocol (HTTP) to provide a mechanism for the exchange of rules and proofs for access control on the Web. Work also included exploring the use of formal reasoning mechanisms to support policy reasoning, scalable (incremental)reasoning and the formalization of the rules and logic models used. We also explored the future research needed to make the widespread deployment of accountability mechanisms on the Web a reality.
