Rein : Where Policies Meet Rules in the Semantic Web
Lalana Kagal, Tim Berners‐Lee · 2005
Abstract. Rein is a decentralized framework for representing and reasoning over distributed policies in the Semantic Web. Policies in Rein use information defined in and inferences made by other policies and web resources forming interconnected policy networks. Rein allows policies to be represented in different policy ontologies and requires the use of N3 rules, a semantic web rule language, for defining the connections in these networks. Reasoning over these networks to obtain policy decisions is done using cwm, an N3 reasoner. Rein consists of three main components- a high level ontology for describing policy networks, mechanisms in N3 for using information and inferences from both policies and web resources, and an engine for inferring policy decisions from policy networks. As part of our future work we would like to look into the use of SWRL and RuleML to develop similar functionality as the Rein framework. 1
