ZapNote: ContentGuard

A digital work is a discrete piece of content or resource such as an electronic document, audio file, video clip, component of application functionality, or other feed of information. As the notion of the digital work has evolved, so has the need to protect that work from improper usage, distribution, or disassembly. ContentGuard’s belief is that DRM will evolve so that best of breed components will be developed by different parties in order to drive interoperability. This model breaks the current closed-loop mindset of DRM providers. In order for this approach to work, a single rights management language is needed, rather than a monolithic trust model. The goal of XrML is to expand the usefulness of digital content, resources, and services to rights holders and users by providing a flexible, extensible, and interoperable industry standard language that is platform, media, and format independent.
