Emergence of different digital rights management (DRM) systems and various rights expression languages (RELs) has led to problems with DRM interoperability and smooth flow of content across different content management systems. The complexity, varied scope, undefined boundaries, and lack of formalism in current RELs pose some of the biggest challenges in addressing DRM interoperability. In this paper, we define a formal language neutral conceptual model for rights expression statements that provides a platform upon which rights statements from different RELs can be mapped, reasoned, and manipulated.
