Media player and file sharing applications and embedded license claims

Media players and file sharing applications should read, verify and display license claims embedded in files. Two example scenarios:

Media Player

When playing a MP3 or OGG file, the player software should look for a license claim and attempt to verify the claim against the verification URL specififed in the claim. If RDF metadata at the verification URL does verify the embedded claim, the player should give some indication of such. For example, a (cc) icon in the player's imitation LCD screen. The icon could be an active link to the verification page. Also, any work metadata found at the verification URL may be used to further enhance track information displayed to the user. Any single file should only need to be verified once, not every time it is played. Please see Media Player.

File Sharing Client

A file sharing client could do everything that a media player does above (indeed, often a media player is built into file sharing clients). In addition, verified licenses should be included in search results. Again, a (cc) icon, or perhaps a green light (sharing ok), might be displayed next to search results. Note that in search results all metadata (including everything from filename to license information) comes from other clients. After downloading a file, the local client should verify a license claim for itself before displaying a positive indicator in a "media library" view or exporting license metadata in respose to external searches. Again, any single file need only be verified once. Please see File Sharing Client.
