Abstract:
|
Contract Expression Languages allow representing business contracts in a digital and structured form. Some examples are the Content Reference Forum format, the OASIS eContracts standard or a proposed extension for MPEG-21 Part 5. These formats have influenced the design of the MPEG-21 Contract Expression Language (CEL), which has been recently specified by modelling the most relevant clauses in audiovisual contracts. The MPEG-21 CEL, described in this paper, defines a language for representing media contracts as XML. It is structured in two schemas, a core defining the structural elements of a contract, and an extension with vocabulary for specific applications. |
