Deploying adaptation in rights exporting

The incompatibility of various Digital Rights Management (DRM) systems remain as an obstacle hampering user experience and business on DRM based services. To increase DRM interoperability, rights exporting currently seems a preferred solution. Based on an earlier DRM model [8,9], we extend and consolidate the concept of rights adaptation in rights exporting. We analyse different ways of adapting rights to be exported and present a general rights adaptation framework.
