MediaMixer will be presented at the Metadata Developer Network Workshop 2013 (http://tech.ebu.ch/MDN2013), organised by the European Broadcasters Union. June 5-6 2013, Geneva, Switzerland. The talk “MediaMixer: facilitating media fragments mixing and its rights management using semantic technologies” to be given by Roberto García of the University of Lleida will focus on how Media Fragments will be also linked to rights information based on a copyright ontology, which integrates licenses, policies and rights expressions based on existing standards like DDEX, ODRL or MPEG-21.
