Protune: Rule Based Policies on the Semantic Web

Abstract

Nowadays, policy is an overloaded term which refer differently to security and privacy policies, business rules, trust management policies, quality of service specification, etc. Many of existing policy languages and frameworks focus on a small subset of these and not on a broader notion of policy.

However, within a company they are typically all interleaved. A company may authorize access to a resource (security & privacy policy) to any client paying for it while at the same time provide a discount (business policy) to any student (trust management policy). In addition, integration with legacy systems which are already existing in most companies must be provided under a low cost. Finally, specification of policies is as hard as developing code. Therefore, proper tools must be provided not only for policy developers but also for normal users to be able to understand those policies.

This presentation will introduce the Protune policy framework which has been developed within the EU REWERSE Network of Excellence. Protune offers a high flexibility for specifying any kind of policy, integrate external systems at the policy level and provide facilities for increasing user awareness, like for example, explanations of the policies in natural language.
