Yuzhong Qu, Xiang Zhang, Huiying Li

Abstract: This paper proposes an Ontology-based Rights Expression Language, called OREL. Based on OWL Web Ontology Language, OREL allows not only users but also machines to handle digital rights at semantics level. The ontology-based rights model of OREL is also presented. The usage of OREL and its advantages against existing RELs are discussed.
