Second Edition of MPEG-21 Media Contract Ontology has been released

Laurent Boch

Some months after its approval ISO/IEC has eventually released the second edition of the Media Contract Ontology of MPEG-21.

The first edition was released in 2013, followed by a Corrigendum in 2015.

This standard, which uses the Web Ontology Language (OWL), such as Contract Expression Language uses XML, was developed in MPEG-21 with the contribution of RAI’s Centre for Research and Technological Innovation.

This is a format that allows you to define machine readable contracts on the rights to exploit audiovisual content and is used within the new RAI rights management system.
