That should be also mentioned in the "Ogg properties" column

Also plesse check the remarks from the F2F minutes review as follow
http://www.w3.org/2011/06/28-mediaann-minutes.html

OGG example

(OGG) identifier: missing
(OGG) title: ok
(OGG) language: missing
(OGG) locator: exist in mapping table, locator is embedded in OGG file, 
but does not have a link ??? needs to be checked
(OGG) locator: locator in RDF should be pointing to the OGG file
(OGG) contributor: missing
(OGG) creator: ok
(OGG) date: ok
(OGG) location: ok
(OGG) description: missing
(OGG) genre: missing
(OGG) relation: missing
(OGG) collection: missing
(OGG) copyright: ok
(OGG) policy: missing, but copyright has a creativecommon
(OGG) publisher: missing
(OGG) targetAudience: missing
(OGG) frameSize: ok
(OGG) compression: ok
(OGG) duration: ok
(OGG) format: missing
(OGG) samplingRate: ok
(OGG) frameRate: ok
(OGG) numTrack: isNumTrack, hasNumTrack must be deleted in mapping table

That should be also mentioned in the "Ogg properties" column
