<div>== Content Metadata Exposure and Content Synchronization Task Force ==<br />
<br />
=== Goals ===<br />
<br />
This task force aims to<br />
<br />
* Investigate how to expose TV metadata to web applications<br />
* Investigate mapping between Media Element API and in- band metadata<br />
* Enable synchronization scenarios up to frame accurate<br />
<br />
==== Our Approach ====<br />
<br />
* We will be gathering (and authoring) use cases related to TV Synchronisation and applications<br />
* We will derive requirements from our use cases. Some will be relevant to Metadata/Sync, others will be contributed to other task forces such as the Terminal TF<br />
* We do not expect to specify or choose any broadcast/content metadata format. Our requirements are likely to be limited to a bridge between the TV/broadcast system and the web stack, allowing discovery and access to this metadata through a standard API.<br />

===== Metadata Formats / Vocabularies =====<br />
<br />
On the mailing-list, a few participants have mentioned existing work on media metadata. References will be listed here.<br />
<br />
* The work of the Media Annotations WG: http://www.w3.org/2008/01/media-annotations-wg.html<br />
* The schema.org schemas and the http://www.w3.org/wiki/TVRadioSchema proposed extensions<br />
* Base Level Metadata (MovieLabs) - This deals with all the base level descriptive metadata so that a digital product can be fully described. http://www.movielabs.com/md/md/index.html<br />
* The Content Recognition Metadata specification (http://www.movielabs.com/crmd/) specifies an XML-based format for the delivery of descriptive metadata from content owners to content recognition entities. A couple of use cases are provided.<br />
* The Entertainment Merchants Association has derived a profile from that specific to digital movie and TV episodic retail: (EMA Core 1.0) -http://www.entmerch.org/programsinitiatives/the-ema-metadata-structure<br />
* Ultraviolet: (in the metadata specs) On this page look for “Technical Specifications” http://uvvu.com/uv-for-business.php<br />
* Indirectly more metadata is available via web api’s from EIDR: http://eidr.org/technology/<br />
* TV and Radio metadata has been extensively studied by TV-Anytime, which has been actively maintained for the last 10 years, which demonstrates it is used http://tech.ebu.ch/tvanytime. The main publication of TV-Anytime are covered by the http://www.w3.org/wiki/TVRadioSchema proposed extensions<br />
* EBU is also working on metadata schemas such as EBUCore (http://tech.ebu.ch/docs/tech/tech3293v1_3.pdf - 1.4 will be released shortly with a refined RDF/XML representation - http://www.ebu.ch/metadata/ontologies/ebucore/20121211/). EBUCore is also being registered in SMPTE to facilitate the introduction of semantic web in production on the long term. The EBUCore ontology is used in key audiovisual archive projects such as EUScreen providing metadata to the European Digital Library Europeana as linked open data using the EBUCore ontology. <br />
* EBU is known for providing a large set of classification schemes as html pages (http://www.ebu.ch/metadata/cs/web/), in xml (http://www.ebu.ch/metadata/cs/) and also in RDF/SKOS (http://www.ebu.ch/metadata/ontologies/skos/).<br />
