Developing a system to interpret MPEG-21 REL or other flexible rights language is often a difficult task, due to the flexibility of the language and the lack of formal semantics. An efficient way to manage this complexity is to translate the license into a set of clearly defined knowledge predicate, and process this knowledge via inference rules using an expert system. This improves computational efficiency and allows authorization request to be verified against a large number of licenses without dependency issues.
