Audio Info

The web has been incorporating multimedia into its pages ever since the release of the Mosaic web browser around 1993. It was shortly thereafter that links to many types of audio started to appear on the web. Even today (April 2007), it is still difficult for a web browser to extract semantic information regarding audio recordings from a web page. Information such as artist, title, speaker, track listing, and publisher are readily available on the same web page that contains the links to the audio files. The Audio Info exploratory discussion is an attempt to create a standard method of marking up metadata and information about one or more audio recordings discussed on a web page.

The Problem

It is difficult for a browser to extract semantic information about an audio recording described on a web page. Metadata such as speaker, musician, publisher, label, title of the work, release date, acquisition link, related image artwork and tags provide relevant context for the audio recording.

Having such information marked up can provide a number of benefits to the viewer. If a web browser understands that a particular web page contains a song performed by an artist, it can produce richer interactions. For example, specific searches may be performed for artists and songs via general search services such as Google and Wikipedia. Specific search services may also be queried such as MusicBrainz, The Internet Archive, FreeDB, or Bitmunk. Additionally, classification by crawlers can become more accurate. If there are 20 tracks found on a page done by the same artist, and that content consumes a significant portion of the page, it can be assumed that the page is not only about music, but also about a particular artist.

The audio information need not be associated with a file. Note that audio content (The Payback by James Brown) is very different from the audio file format (192Kbps, stereo MP3). The goal of this discussion is to create a Microformat draft for marking up audio metadata and information.

A NOTE ABOUT CONTRIBUTING - USE TEMPLATES

Due to the large number of audio sites, tallying statistical information for this discussion is difficult. A small python script has been written to do the job, but for it to work, we need to be careful about how we mark up information.

Please use the following template when adding information about an audio collection description:

* [ http://www.example.com Website Name]
** [ http://www.example.com/album_example/ Album Example]
*** Information displayed: artist, title, tracks, release date, label, genre, web-based purchase, cover image, 
                           price, format, sample, length, summary, physical-based purchase, publisher, reviews 

Please use the following template when adding information about an audio song, track or sample description:

* [ http://www.example.com Website Name]
** [ http://www.example.com/song_example/ Song Example]
*** Information displayed: title, track number, sample, web-based purchase, artist, price, length, release date, album, genre, format, rating, label 

If you need to add more information that is displayed, please use a common term to describe the information. For example, if you need to mention that an artists hometown is mentioned, adding a term such as hometown would be acceptable.

Real-World Examples

Speech

Publication of audio speeches on blogs is often called "podcasting". In essence though, it is simply audio speech publishing. Quotes of audio files are beginning to appear, and publishers are putting up files with links to other audio files they've quoted from. Most audio appears to often have the same base elements as video and photos, with the exception of quotes.

Music Podcasting

Music podcasts are a totally different beast, but a very important one. They usually consist of one big file containg multiples songs, speech, audio advertising and prerecorded audio (such as voicemail or promos)
