The ISO/IEC 21000-21:2018 (KR) standard, published by the Korea Agency for Technology and Standards (KATS), defines an Ontology of Media Rights Language (OMRL) as part of the Multimedia Framework under MPEG-21. This document specifies a formal ontology to describe rights and permissions associated with digital media objects. The OMRL provides a standardized way to represent and exchange information about usage terms, conditions, and restrictions related to multimedia content. It aims at facilitating interoperability among different systems that manage or consume digital media assets by providing clear definitions for key concepts such as 'rights', 'permissions', and 'licenses'. This standard is crucial in the context of copyright management, distribution models for digital content, and the development of intelligent agents capable of automatically negotiating usage rights over networked environments. The OMRL ontology supports detailed descriptions allowing for precise control over how media can be used by various entities across different contexts.
