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. In most cases, it is still difficult for a web browser to extract semantic information about a particular speaker, musician, or piece of audio. In most cases, such information exists on the same web page that contains the links. 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 on a web page.

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.

It is difficult for a browser to extract semantic information about a piece of audio listed on a web page. Metadata such as speaker, musician, publisher, label, title of the work, release date, acquisition link, related image artwork and tags can be relevant to a particular audio file.

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 title performed by an artist, it may produce several new methods of interaction. For example, specific searches may be performed for artists and song titles 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.

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.

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.

==== 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). Podcasts consists of multiple songs and therefore might need another microformat, one that makes a collection of multiple songs and only one file.

====Mashups, remixes, cut-ups and audio-collages====
 +
 +
Some music is in fact made from other samples of other music. The information on those tracks then must contain another audio information, on the original track. Some of those tracks are posted to sampling communities and therefore are remixed again, creating a fractal-like information. Most sites, thou, will only show the first layer: the music directly derivated

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.

Individual Publishing of Speech

  • Microformats: Web Essentials Audio
    • Appears to be composed of:
      • title/summary of the recording
      • clickable hyperlink to the recording (MP3)
    • Contextual:
      • (primary) speaker is indicated in nearby text
  • Chris Pirillo podcast
    • This example has a Title, Html URL, media URL(s), description or summary, categories/tags underneath what is viewable, and date. +10k
  • Evil Genius Chronicles podcast
    • This example has a Title, Html URL, description or summary, quotes URLs and descriptions, licence, creator, tags and publish time and date. +10k records.
  • media published from a blog, Jake Steinfeld's Audio Blog NOTE: this record had trouble because mediawiki blocks any DOTbiz domains and so while this domain coincidentally has a DOTbizbyjake.com name that is not a TLD, it was still blocked in the loading of the page with this example. So please adjust the URL manually and then visit the site.
    • This example has a Title, Html URL, media URL, creator and publish time and date. +10k records.
  • Buzz Out Loud
    • episode example
      • Information displayed: Title, episode summary, length, date

Individual Publishing of Music

  • Brad Sucks » music
    • Has album title, song title, separate link to more info, inline flash player, and play link (to mp3)
  • Portishead Remixed
    • Whole page is for one album (a mash-up remix of a Portishead album). Has Album Track Number and Title (linked to mp3) and Remixer's name, plus cover art. Also a link to the BitTorrent download of the whole album.

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). Podcasts consists of multiple songs and therefore might need another microformat, one that makes a collection of multiple songs and only one file.

Properties

These properties are in alphabetical order and in no way represent the frequency of their use in the examples. The property names are also not final and probably will not be used when the Microformat vocabulary is decided. Deciding the vocabulary of the Microformat is not performed at this stage of examples collection and analysis. These property names and definitions are listed here in an attempt to keep the current and future example analysis teams using the same definitions for property names.

  • RSS Feed - An RSS feed for the podcast exists on the page.
  • contributor - The person that created or helped create the podcast.
  • description - The description of the podcast.
  • download - The full download location for the podcast.
  • format - The audio format for the podcast.
  • genre - The genre for the podcast.
  • label - The publishing company for the podcast.
  • length - The length of the podcast.
  • photo - A representative image of the podcast.
  • position - the number or index of the podcast.
  • price - The price one must pay to legally acquire the podcast.
  • published - The date the podcast was released.
  • sample - A sample of the podcast
  • section - The name of a section of a podcast.
  • title - The title of the podcast
  • web-based purchase - A place to legally pay for and acquire the full podcast.

Mashups, remixes, cut-ups and audio-collages

Some music is in fact made from other samples of other music. The information on those tracks then must contain another audio information, on the original track. Some of those tracks are posted to sampling communities and therefore are remixed again, creating a fractal-like information. Most sites, thou, will only show the first layer: the music directly derivated

Top Lists

Top lists are lists of music or audio that are rated in order. Examples are a the "Billboard Top 100", "Top 100 Blue Grass hits of 2005", "Top Beatles Remixes of All Time", etc.

Existing Practices

Listed below is an overview of existing patterns and practices found in the wild for audio information and metadata.

Other schema

  • MPEG4 - includes list of field names, for example "Genre", "Track number", "Disk number".


Summary of common patterns discovered

  • There are two major forms of audio - single recordings and collections of recordings. Sometimes an audio collection can exist within a single file, with each recording playing back-to-back within the file. -- ManuSporny
  • On music service sites, the audio album is almost always described on the same page as the track listings. -- ManuSporny

Other attempts to solve The Problem

  • media-info-examples - Attempted to find an uber-microformat for describing media. Turned out to be too large of a task, thus the problem was split into attempting to create microformats for audio, video and images.
  • audio-info-formats - Various formats have attempted to describe audio metadata from within the files.
