NBN ISO/IEC 21000-21:2021

This document 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.
Media Contract Ontology (MCO) aims to digitally express agreements made in environments using
ISO/IEC 21000. These agreements are contracts for transactions of content packed as Digital Items, as
well as for services provided around this content by means of a sematic representation.
The range of contracts under scope are as follows:
— contracts about transactions on rights for the exploitation of content as MPEG-21 Digital Items;
— contracts about the provision of MPEG-21-based services, like delivery, identification, encryption,
search and others.
However, MCO can also be used as electronic format for contracts on the trade of media rights beyond
the MPEG framework.
