+ <h3>Property Selection Criteria</h3>
+ <ul>
+ <li><b>Simplicity and Practicability</b>: the metadata dictionary should define the minimal
+ set of properties that are practically used in deployed plaforms and
+ services. Thanks to the prevailing cloud based media services, user
+ created media contents tend to be packed with related metadata more
+ than ever. Tags and location information are representative such properties.
+ While maintaining minimal set of attributes, the <a>Media</a> dictionary covers
+ wide use cases from as simple as media information display to virtual image gallery,
+ media player apps, and so on.
+ </li><br>
+ <li>
+ <b>Commonality</b>: as a great deal of metadata formats are defined and used across various communities,
+ it has to be considered that the attributes of the <a>Media</a> dictionary cover generic use cases.
+ Hence, for the sake of property selection, the previous metadata survey work, quoted as the <a href="http://www.w3.org/TR/2012/REC-mediaont-10-20120209/#core-property-lists">core set</a>,
+ of Media Ontology WG has been refered to. The <a href="http://www.w3.org/TR/2012/REC-mediaont-10-20120209/#core-property-lists">core set</a> already considered quite a few metadata formats
+ including CableLabs 1.1, DIG35, Dublin Core, EBUCore, EXIF 2.2, ID3, IPTC, LOM 2.1, Media RSS, MPEG-7,
+ OGG, QuickTime, DMS-1, TTML, TV-Anytime, TXFeed, XMP and YouTube. The <a>Media</a> dictionary defintion
+ naturally falls in the subset of the <a href="http://www.w3.org/TR/2012/REC-mediaont-10-20120209/#core-property-lists">core set</a> with a few additional attributes (tags, likeCount and viewCount)
+ to support web services.
+ </li>
+ </ul>
+ </section>
+ <section>
+ <h3>Excluded Properties</h3>
+ <p>
+ The following properties are excluded from the <a>Media</a> dictionary
+ definition due to the lack of necessity in most of the applications
+ and services. However, the retention of the properties can be considered
+ upon any strong use cases under ongoing discussion in the group.
