The Rein Policy Framework for the Semantic Web*This Version : http://dig.csail.mit.edu/2005/09/rein/ Previous Version : http://dig.csail.mit.edu/2005/05/rein/ Rein (pronounced rain) is a framework for representing and reasoning over policies in the Semantic Web. Rein (Rei and N3) uses high level Rei concepts for policies and N3 rules to connect these policies to each other and the Web. Rein includes an ontology (N3, RDF) for describing how resources, policies, policy languages, and meta policies are related to each other. When described using the Rein ontology, these entities form Rein policy networks. The Rein engine, a set of N3 rules, reasons over these Rein policy networks to verify whether a request made for a resource within the network is valid. A request includes the authentication properties of the user and the URI of the resource. Overview : Installating Example Installating
