Ironically, I was just charged with throwing together a video page much like Google Video's for CES. It is to bad there wasn't a preexisting microformat to pull from. Unfortunately, I am a bit of an expert in the area of media info tagging, although in a file container (not web) specific context, so take what I say with a grain of salt. Off hand, I would say the primary existing file tagging systems (in order of use) are ID3v1 ID3v2 RIFF AAF/MPEG-7 A comparison of some different formats tags can be found here: http://www.matroska.org/technical/specs/tagging/othertagsystems/comparetable.html http://hobba.hobba.nl/audio/tag_frame_reference.html I created the top site and it has more formats, but it has been almost two years since I touched it. Both sites are largely based on each other. AAF is not listed as it is an extremely large standard, and as it is based on MPEG-7, I have no idea what the licensing is like for it. For a starting point, I would look at ID3v1 as it is common to add lots of tagging information to audio files, and ID3v1 was the simplest and first to really cater to this market. A quick intro to it is available here: http://www.id3.org/id3v1.html The information that is contained is: Title (name of the song) Artist (name of the band/singer/whatever) Album (Name of the CD or album the song is from) Year (year the song or CD was released) Comment (Whatever you want to say about the song) Genre (We have both kinds of music, country and western.) Track (Which track from a CD the song is from) Obviously people found this pretty restricting, given how much effort was poured into making new tagging standards. Unfortunately, most of what was developed is either to complex and restrictive (ID3V2) or to loose to be meaningful over a large area (Ogg Comments). Most of the items from the ID3v1 would be pretty simple to apply. I am guessing that you could use some sort of hCard for the Artist, although I don't know the implications of having an hCard for a group of people instead of an individual. Either way, an hCard being used for the Artist would alleviate much of the tagging information people want just for audio. (Could someone please come up with an alternate name for 'Title' as this seems to be used everywhere?) In addition to the above items, here are things that people often seem to want to include and/or display. Bitrate (I'm not sure why this isn't in any of the strawman media-metadata-examples as I see it everywhere.) Resolution Segmentations (Track on a CD, CD in a set. Episode in a season, season in a running. Part of a larger set where the division occurs solely due to size.) Dates (When it was recorded, when it was released, when it was re-released, when this file was encoded) Size (in bytes/octets) Length (in seconds) Cover (The DVD/CD cover, posters, screenshots) I'm thinking that a Rating and a few other pieces of information can be consolidated to hReview. Cost is another one, but that really should also be pulled from another microformat. Has there been any progress on listings? http://microformats.org/wiki/listing-brainstorming I list the above not with the expectation that all of it should be defined, but rather as a listing of what I have seen as the type of information that people usually want to see, although as I said, most of my experience comes from offline file storage.
