Rei : A Policy Specification Language
Status: Past project
Rei is a policy language based in OWL-Lite that allows policies to be specified as constraints over allowable and obligated actions on resources in the environment. Rei also includes logic-like variables giving it the flexibility to specify relations like role value maps that are not directly possible in OWL. Rei includes meta policy specifications for conflict resolution, speech acts for remote policy management and policy analysis specifications like what-if analysis and use-case management making it a suitable candidate for adaptable security in the environments under consideration. The Rei engine, developed in XSB, reasons over Rei policies and domain knowledge in RDF and OWL to provide answers about the current permissions and obligations of an entity, which are used to guide the entity's behavior.
