This part of ISO/IEC 21000 specifies a language for representing contracts in the Multimedia Framework formed for the transaction of MPEG-21 Digital Items or services related to the MPEG-21 Framework. The Contract Expression Language (CEL) aims at digitally representing the agreements made in an environment of ISO/IEC 21000 use. These contracts include those about both transactions of content packed as Digital Items as well as services provided around this content. T he range of contracts under scope are: - contracts about transactions of content as MPEG-21 Digital Items; - contracts about the provision of MPEG-21-based services, i.e. delivery, identification, encryption and search. T he aspects represented by CEL contracts include: - the textual clauses, in natural language as they are in the narrative contract, duly structured; - the operative clauses, as computer language expressions.
