scope:

This part of ISO/IEC 21000 specifies an ontology 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 Media Contract Ontology (MCO) aims at digitally expressing the agreements made in an environment of use of ISO/IEC 21000, being these contracts about both transactions of content packed as Digital Items as well as services provided around this content, by means of a semantic representation. The range of contracts under scope includes: - Contracts about transactions of content as MPEG-21 Digital Items; - Contracts about the provision of MPEG-21-based services, such as delivery, identification, encryption, search and others. The aspects represented by MCO contracts include: - The textual clauses, in natural language as they are in the narrative contract, duly structured; - The operative clauses, as computer language expressions.
