The mission of the Media Annotations Working Group, part of the Video in the Web Activity, is to provide an ontology and API designed to facilitate cross-community data integration of information related to media objects in the Web, such as video, audio and images..

The Media Annotations Working Group was closed on 30 May 2014, having successfully published the following Recommendations: the Ontology for Media Resources 1.0 and the Metadata API for Media Resources 1.0.
