The Internet has spawned a revolution in the way people distribute content and accessservices. At the same time, the availability of broadband and wireless networks has increased, as have the capability and portability of computing and consumer electronic devices. Thesefactors have fueled the development of new technologies to automate, manage, and secure content flow and service access over the Internet. The recently approved ISO standard, MPEG-21 Rights Expression Language (REL), is one such technology. This language is precise, flexible,extensible, and rich in expressing rights. Thus, it can support reliable, flexible, and costeffectiveinteroperable digital rights management (DRM) systems and applications for electronic commerce and enterprise management of content and services.
