Discussion

Removes user-identifying metadata items, such as location information and leaves only metadata releated to commerce or playback itself. For example: playback, copyright, and commercial-related metadata, such as a purchaser’s ID as set by a vendor of digital media, along with metadata either derivable from the media itself or necessary for its proper behavior are all left intact.
