Nonius: Implementing a DRM Extension to an XML Browser

Overview The paper describes experiences, ideas, and problems that were discovered while developing a Digital Rights Management (DRM) extension to an XML browser. The supported rights description language is ODRL. The most significant implemented features are restrictions related to an individual, time, and usage-counts. On the other hand, some interesting features were intentionally left out. They include for example, aspect and target constraints as well as many security features. The most difficult tasks in implementing a DRM system are related to security and parsers. A secure DRM system requires the support of hardware devices. A DRM document parser depends profoundly on a flexible software architecture. Merging certificates and implementing an interface for creating certificates are also demanding.
