| Abstract: | Generic rights expression language allowing interoperability across
different computing environments including resource usage of different
applications. A formal framework for usage management provides
scaffolding upon which interoperable usage management systems can be
built. Certain features of the framework are standardized, such as the
operational semantics, including areas free of standards that necessitate
choice and innovation to achieve a balance of flexibility and usability
for interoperability in usage management systems. |
