It shows the design and the implementation of a rights expression exchange framework. The framework allows DRM systems to exchange electronic contracts, formulated in a standardized rights expression language, and thus provides DRM system interoperability. The work introduces a methodology for the standardized composition, exchange and processing of electronic contracts or rights expressions.
