== Introduction ==

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.

In order to enable and encourage the sharing, distribution, syndication, and aggregation of audio content, the authors propose the hAudio microformat, an open standard for distributed audio metadata. The authors have researched both numerous [[audio-info-examples]] in the wild and earlier attempts at [[audio-info-formats]], and have designed hAudio around a simple minimal schema for audio content. Feedback is encouraged on the [[haudio-feedback|hAudio feedback]] page.

=== Inspiration and Acknowledgments ===

Many thanks to the various individuals that did research and proposed ideas and discussion related to media info and audio info in general. Among the many participants are [[RodBegbie]], Dean Hudson, [http://tantek.com/log/ Tantek Çelik], [http://napsterization.org/stories/ Mary Hodder], [http://joshkinberg.com/blog/ Joshua Kinberg], ChrisMessina, and [http://onlisareinsradar.com/ Lisa Rein].

=== Scope ===

Audio content consistently share several common fields. Where possible hAudio has been based on this minimal common subset.

==== Out of scope ====

Fields that are type-specific have been omitted from hAudio. It is important that hAudio be kept simple and minimal from the start. Additional features can be added as deemed necessary by practical implementation experience.

The concept of a universal audio identifier, that is, how to identify the same audio album, song, speech, or podcast across different music and audio sites, though something very useful to have, is outside the scope of this format.

== Semantic XHTML Design Principles ==

{{semantic-xhtml-design-principles}}

== Format ==

=== In General ===
The hAudio format is based on a set of fields common to numerous audio content sites and formats in use today on the web. Where possible field names have been chosen based on those defined by the related [[hcard|hCard]] standards.

=== Schema ===

The hAudio schema consists of the following:

* hAudio ('''<code>haudio</code>''')
** '''audio-title''' required. text.
** '''contributor'''. optional. using [[hCard]].
** '''published-date'''. optional. using [[datetime-design-pattern]].
** '''rel-sample'''. optional. sample file/stream using [[rel-design-pattern]] with <code>sample</code> as the <code>mf-rel-value</code>.
** '''rel-enclosure'''. optional. full download of file using [[rel-enclosure]].
** '''rel-payment'''. optional. link to purchase process using [[rel-payment]].
** '''image-summary'''. optional. using HTML and XHTML tag <code>img</code>.
** '''category'''. optional. text.
** '''duration'''. optional. ISO-8601 time duration using [[abbr-design-pattern]] (re-used from [[hcalendar]]).
** '''price'''. optional. using [[currency-proposal]].

=== Field details ===

The fields of the hAudio schema represent the following:

==== hAudio ====

An hAudio is used to identify and describe metadata associated with an individual audio recording.

* an hAudio element is identified by class name <code>haudio</code>

==== Audio Title ====

The audio title of an audio recording is a short textual description used to identify the work among interested parties. This can be the title of a speech, song title, or short description regarding a sound effect.

* The element is identified by the class name <code>audio-title</code>.
* hAudio MUST have an audio title.

==== Contributor ====

A Contributor is any entity that takes part in the creation and distribution of an audio recording. Examples include: artist, publisher, guitarist, vocalist, violinist, lead singer, backup singer, bassist, drummer, manager, and roadie.

* The element is identified by the class name <code>contributor</code>.
* hAudio MAY include one or more contributors.
* The contents of the element must include a valid [[hCard]] Microformat.
* The <code>role</code> field should be used to specify the Contributor's responsibility related to the audio recording.
* If multiple Contributors are specified without <code>role</code> specifications, it may be assumed that the first role mentioned is the artist.

==== Published Date ====

The Published Date specifies the date that the audio recording was made available to the public. Examples include: The airing date of a radio broadcast, the day a speech was given, or the day a music album was made available for sale.

* The element is identified by the class name <code>published-date</code>.
* hAudio MAY include one or more <code>published-date</code>s.
* The contents of the element must include a date format compliant with the [[datetime-design-pattern]].

==== Sample ====

A Sample URL specifies from where an excerpt of the audio recording may be retrieved.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>sample</code>.
* hAudio MAY include one or more URL <code>sample</code>s.
* The URL SHOULD point to a directly accessible stream or file.
* The type of the sample MAY be specified by using the <code>type</code> specifier for a URL.

==== Full Download (Enclosure) ====

An Full Download URL specifies from where the full version of an audio recording may be retrieved. The URL MUST point to a direct link to a file.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>enclosure</code>.
* hAudio MAY include one or more <code>enclosure</code> URLs.
* The type of the file MAY be specified by using the <code>type</code> specifier for a URL.

==== Purchase (Payment) ====

An Purchase URL specifies from where the full version of an audio recording may be purchased. The URL MUST point to a page that contains a purchase process.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>payment</code>.
* hAudio MAY include one or more <code>payment</code> URLs.
* The type of the file MAY be specified by using the <code>type</code> specifier for a URL.

==== Image Summary ====

An Image Summary specifies an image that should be used to summarize the audio recording. Examples include: the image of a speaker, an audio album cover image, or a picture from a concert.

* The element is identified by the class name <code>image-summary</code>.
* hAudio MAY include one or more <code>image-summary</code> images.
* The element must be an <img> element.

==== Category ====

The Category specifies the genre or style used to classify the audio recording. Examples include: blues, rock, motivational, spoken word, or sound effect.

* The element is identified by the class name <code>category</code>.
* hAudio MAY include one or more <code>category</code> elements.

==== Duration ====

The Duration specifies the length in time of the audio recording in seconds. Examples include: 104 seconds, 3:23, and 4 minutes.

* The element is identified by the class name <code>duration</code>.
* hAudio MAY include one <code>duration</code> element.
* The contents of the element SHOULD use the [[abbr-design-pattern]] whose title attribute contains an ISO-8601 formatted duration, specifically in seconds. This allows us to expand into specifying time slices and other time markup in the future, but keep parsing simple for now. An example of 3:23 (203 seconds) would be "P203S" in ISO 8601 format. Currently, all abbr attributes specifying duration SHOULD be in seconds.

==== Price ====

The Price specifies the amount of currency that must be exchanged for acquisition of a full specimen of the audio recording. Examples include: One Dollar, $2, and £4.

* The element is identified by the class name <code>price</code>.
* hAudio MAY include one or more <code>price</code> elements.
* The contents of the element SHOULD use the [[currency-proposal]].

=== More Semantic Equivalents ===

For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:

* For any "url", use <code><a class="url" href="...">...</a></code> inside the element with the class name 'haudio' in hAudio.
* And for "image-summary", use <code><img class="image-summary" src="..." alt="Photo of ..." /></code>

==== Language ====

* To explicitly convey the natural language that an hAudio is written in, use the standard (X)HTML 'lang' attribute on the element with class="haudio", e.g. <code><div class="haudio" lang="en"> ... </div></code> If portions of an hAudio (e.g. the item name) are in a different language, use the 'lang' attribute on those portions.
* hAudio processors which need to handle the language of reviews MUST process the standard (X)HTML 'lang' attribute as specified.

=== Human vs. Machine Readable ===
If an <code><abbr></code> element is used for a property, then its '<code>title</code>' attribute is used for the value of the property, instead of the contents of the element, which can then be used to provide a user-friendly alternate presentation of the value.

Similarly, if an <code><img /></code> element is used for one or more properties, it MUST be treated as follows:

# For the "image-summary" property and any other property that takes a URL as its value, the <code>src="..."</code> attribute provides the property value.
# For other properties, the <code><img /></code> element's '<code>alt</code>' attribute is the value of the property.

=== Notes ===

This section is informative.

* By marking up audio content with the hAudio microformat, the expectation is communicated that information about the content MAY be indexed. This has no impact on the copyright of the content itself which the publisher may explicitly specify using [[rel-license]] as specified above.
* The enumerated list of item types is under development and may be extended.
* Each type may have custom hAudio fields that follow the common set.
* Additional details about a particular item should be specified with the rest of the item's info at the URL provided for the item.

The Duration specifies the length in time of the audio recording in seconds. Examples include: 104 seconds, 3:23, and 4 minutes.

* The element is identified by the class name <code>duration</code>.
* hAudio MAY include one <code>duration</code> element.
* The contents of the element SHOULD use the [[abbr-design-pattern]] whose title attribute contains an ISO-8601 formatted duration, specifically in seconds. This allows us to expand into specifying time slices and other time markup in the future, but keep parsing simple for now. An example of 3:23 (203 seconds) would be "P203S" in ISO 8601 format. Currently, all abbr attributes specifying duration SHOULD be in seconds.

==== Price ====

The Price specifies the amount of currency that must be exchanged for acquisition of a full specimen of the audio recording. Examples include: One Dollar, $2, and £4.

* The element is identified by the class name <code>price</code>.
* hAudio MAY include one or more <code>price</code> elements.
* The contents of the element SHOULD use the [[currency-proposal]].

=== More Semantic Equivalents ===

For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:

* For any "url", use <code><a class="url" href="...">...</a></code> inside the element with the class name 'haudio' in hAudio.
* And for "image-summary", use <code><img class="image-summary" src="..." alt="Photo of ..." /></code>

==== Language ====

* To explicitly convey the natural language that an hAudio is written in, use the standard (X)HTML 'lang' attribute on the element with class="haudio", e.g. <code><div class="haudio" lang="en"> ... </div></code> If portions of an hAudio (e.g. the item name) are in a different language, use the 'lang' attribute on those portions.
* hAudio processors which need to handle the language of reviews MUST process the standard (X)HTML 'lang' attribute as specified.

=== Human vs. Machine Readable ===
If an <code><abbr></code> element is used for a property, then its '<code>title</code>' attribute is used for the value of the property, instead of the contents of the element, which can then be used to provide a user-friendly alternate presentation of the value.

Similarly, if an <code><img /></code> element is used for one or more properties, it MUST be treated as follows:

# For the "image-summary" property and any other property that takes a URL as its value, the <code>src="..."</code> attribute provides the property value.
# For other properties, the <code><img /></code> element's '<code>alt</code>' attribute is the value of the property.

=== Notes ===

This section is informative.

* By marking up audio content with the hAudio microformat, the expectation is communicated that information about the content MAY be indexed. This has no impact on the copyright of the content itself which the publisher may explicitly specify using [[rel-license]] as specified above.
* The enumerated list of item types is under development and may be extended.
* Each type may have custom hAudio fields that follow the common set.
* Additional details about a particular item should be specified with the rest of the item's info at the URL provided for the item.

__TOC__

== Introduction ==

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.

In order to enable and encourage the sharing, distribution, syndication, and aggregation of audio content, the authors propose the hAudio microformat, an open standard for distributed audio metadata. The authors have researched both numerous [[audio-info-examples]] in the wild and earlier attempts at [[audio-info-formats]], and have designed hAudio around a simple minimal schema for audio content. Feedback is encouraged on the [[haudio-feedback|hAudio feedback]] page.

=== Inspiration and Acknowledgments ===

Many thanks to the various individuals that did research and proposed ideas and discussion related to media info and audio info in general. Among the many participants are [[RodBegbie]], Dean Hudson, [http://tantek.com/log/ Tantek Çelik], [http://napsterization.org/stories/ Mary Hodder], [http://joshkinberg.com/blog/ Joshua Kinberg], ChrisMessina, and [http://onlisareinsradar.com/ Lisa Rein].

=== Scope ===

Audio content consistently share several common fields. Where possible hAudio has been based on this minimal common subset.

==== Out of scope ====

Fields that are type-specific have been omitted from hAudio. It is important that hAudio be kept simple and minimal from the start. Additional features can be added as deemed necessary by practical implementation experience.

The concept of a universal audio identifier, that is, how to identify the same audio album, song, speech, or podcast across different music and audio sites, though something very useful to have, is outside the scope of this format.

== Semantic XHTML Design Principles ==

{{semantic-xhtml-design-principles}}

== Format ==

=== In General ===
The hAudio format is based on a set of fields common to numerous audio content sites and formats in use today on the web. Where possible field names have been chosen based on those defined by the related [[hcard|hCard]] standards.

=== Schema ===

The hAudio schema consists of the following:

* hAudio ('''<code>haudio</code>''')
** '''audio-title''' required. text.
** '''contributor'''. optional. using [[hCard]].
** '''published-date'''. optional. using [[datetime-design-pattern]].
** '''rel-sample'''. optional. sample file/stream using [[rel-design-pattern]] with <code>sample</code> as the <code>mf-rel-value</code>.
** '''rel-enclosure'''. optional. full download of file using [[rel-enclosure]].
** '''rel-payment'''. optional. link to purchase process using [[rel-payment]].
** '''image-summary'''. optional. using HTML and XHTML tag <code>img</code>.
** '''category'''. optional. text.
** '''duration'''. optional. ISO-8601 time duration using [[abbr-design-pattern]] (re-used from [[hcalendar]]).
** '''price'''. optional. using [[currency-proposal]].

=== Field details ===

The fields of the hAudio schema represent the following:

==== hAudio ====

An hAudio is used to identify and describe metadata associated with an individual audio recording.

* an hAudio element is identified by class name <code>haudio</code>

==== Audio Title ====

The audio title of an audio recording is a short textual description used to identify the work among interested parties. This can be the title of a speech, song title, or short description regarding a sound effect.

* The element is identified by the class name <code>audio-title</code>.
* hAudio MUST have an audio title.

==== Contributor ====

A Contributor is any entity that takes part in the creation and distribution of an audio recording. Examples include: artist, publisher, guitarist, vocalist, violinist, lead singer, backup singer, bassist, drummer, manager, and roadie.

* The element is identified by the class name <code>contributor</code>.
* hAudio MAY include one or more contributors.
* The contents of the element must include a valid [[hCard]] Microformat.
* The <code>role</code> field should be used to specify the Contributor's responsibility related to the audio recording.
* If multiple Contributors are specified without <code>role</code> specifications, it may be assumed that the first role mentioned is the artist.

==== Published Date ====

The Published Date specifies the date that the audio recording was made available to the public. Examples include: The airing date of a radio broadcast, the day a speech was given, or the day a music album was made available for sale.

* The element is identified by the class name <code>published-date</code>.
* hAudio MAY include one or more <code>published-date</code>s.
* The contents of the element must include a date format compliant with the [[datetime-design-pattern]].

==== Sample ====

A Sample URL specifies from where an excerpt of the audio recording may be retrieved.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>sample</code>.
* hAudio MAY include one or more URL <code>sample</code>s.
* The URL SHOULD point to a directly accessible stream or file.
* The type of the sample MAY be specified by using the <code>type</code> specifier for a URL.

==== Full Download (Enclosure) ====

An Full Download URL specifies from where the full version of an audio recording may be retrieved. The URL MUST point to a direct link to a file.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>enclosure</code>.
* hAudio MAY include one or more <code>enclosure</code> URLs.
* The type of the file MAY be specified by using the <code>type</code> specifier for a URL.

==== Purchase (Payment) ====

An Purchase URL specifies from where the full version of an audio recording may be purchased. The URL MUST point to a page that contains a purchase process.

* The element is identified by a URL fitting the [[rel-design-pattern]], the rel content being <code>payment</code>.
* hAudio MAY include one or more <code>payment</code> URLs.
* The type of the file MAY be specified by using the <code>type</code> specifier for a URL.

==== Image Summary ====

An Image Summary specifies an image that should be used to summarize the audio recording. Examples include: the image of a speaker, an audio album cover image, or a picture from a concert.

* The element is identified by the class name <code>image-summary</code>.
* hAudio MAY include one or more <code>image-summary</code> images.
* The element must be an <img> element.

==== Category ====

The Category specifies the genre or style used to classify the audio recording. Examples include: blues, rock, motivational, spoken word, or sound effect.

* The element is identified by the class name <code>category</code>.
* hAudio MAY include one or more <code>category</code> elements.

==== Duration ====

The Duration specifies the length in time of the audio recording in seconds. Examples include: 104 seconds, 3:23, and 4 minutes.

* The element is identified by the class name <code>duration</code>.
* hAudio MAY include one <code>duration</code> element.
* The contents of the element SHOULD use the [[abbr-design-pattern]] whose title attribute contains an ISO-8601 formatted duration, specifically in seconds. This allows us to expand into specifying time slices and other time markup in the future, but keep parsing simple for now. An example of 3:23 (203 seconds) would be "P203S" in ISO 8601 format. Currently, all abbr attributes specifying duration SHOULD be in seconds.

==== Price ====

The Price specifies the amount of currency that must be exchanged for acquisition of a full specimen of the audio recording. Examples include: One Dollar, $2, and £4.

* The element is identified by the class name <code>price</code>.
* hAudio MAY include one or more <code>price</code> elements.
* The contents of the element SHOULD use the [[currency-proposal]].

=== More Semantic Equivalents ===

For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:

* For any "url", use <code><a class="url" href="...">...</a></code> inside the element with the class name 'haudio' in hAudio.
* And for "image-summary", use <code><img class="image-summary" src="..." alt="Photo of ..." /></code>

==== Language ====

* To explicitly convey the natural language that an hAudio is written in, use the standard (X)HTML 'lang' attribute on the element with class="haudio", e.g. <code><div class="haudio" lang="en"> ... </div></code> If portions of an hAudio (e.g. the item name) are in a different language, use the 'lang' attribute on those portions.
* hAudio processors which need to handle the language of reviews MUST process the standard (X)HTML 'lang' attribute as specified.

=== Human vs. Machine Readable ===
If an <code><abbr></code> element is used for a property, then its '<code>title</code>' attribute is used for the value of the property, instead of the contents of the element, which can then be used to provide a user-friendly alternate presentation of the value.

Similarly, if an <code><img /></code> element is used for one or more properties, it MUST be treated as follows:

# For other properties, the <code><img /></code> element's '<code>alt</code>' attribute is the value of the property.

This section is informative.

* By marking up audio content with the hAudio microformat, the expectation is communicated that information about the content MAY be indexed. This has no impact on the copyright of the content itself which the publisher may explicitly specify using [[rel-license]] as specified above.
* The enumerated list of item types is under development and may be extended.

* Additional details about a particular item should be specified with the rest of the item's info at the URL provided for the item.

AlexandreVandeSande: /* Disadvantages */

<h1>Accessibility</h1>

This page documents microformats and accessibility in general, in particular advantages that adopting microformats provide for accessibility, and for documenting techniques for making microformats more accessible.

We should all strive to make our published microformats, parser implementations, and this wiki, accessible to all users, regardless of their physical abilities and needs, within the limits of the time and resources of the microformats community. Readers are advised to follow the [http://www.w3.org/TR/WCAG10/ W3C's Web Content Accessibility Guidelines 1.0], to at least level 2. Further advice is available on the [http://www.accessifyforum.com/ Accessify Forums].

__TOC__

==Advantages==
Some microformats have potential accessibility advantages.

===hCard===
*<code>tel</code> in [[hcard|hCard]]: use <code>style="speak-numeral:digits"</code>, so that telephone numbers are read by aural browsers as, for example, "five-five-five one-two-three-four" and not "five-hundred and fifty-five, one-thousand, two-hundred and thirty-two". ''Note: This is not an advantage to Microformats. It is a CSS best practice and can be used with or without hCard. This should probably be moved to a [[css-best-practices|CSS Best Practices]] page. - JamesCraig''

==Disadvantages==
Some microformats have potential accessibility disadvantages.

===abbr-design-pattern===
*As mentioned on external sites (see:[[accessibility-issues]]) and on the microformats-discuss list, the abbr-design-pattern (used in [[hcard|hCard]], [[hcalendar|hCalendar]], [[geo|GEO]] and others) is in violation of WCAG1 and WCAG2, and has potentially harmful accessibility side-effects of reading machine data to screen reader users rendering human content inaccessible.

===anchor-include-pattern===
*As mentioned on [[accessibility-issues]], the anchor-include-pattern is in violation of WCAG1 and WCAG2, and has potentially harmful accessibility side effects due to the missing link text.

==External testimonials==

(And then it would just be a ratification kind of thing.)</p><p>...</p><p>In fact, it is likely to be good for accessibility, as the tools for consuming microformats often require valid code.</p></blockquote>

2007-05-07T21:05:08Z

AlexandreVandeSande: acessibility issues

'''This page is a draft.'''

= Datetime Design Pattern =
This is a page for exploring a datetime design pattern.

== Purpose ==
* Use the [[datetime-design-pattern]] to make datetimes that are human readable also formally machine readable.

== Practical Need ==
* This design pattern arose as a result of solving the practical need for human readable dates for [[hcalendar|hCalendar]].

== How to use it ==
* enclose the human-friendly datetime that you want to make machine readable with <code><abbr></code>
* as per the [[class-design-pattern]], add the appropriate <code>class</code> attribute to the <code>abbr</code> element
* add a <code>title</code> attribute to the <code>abbr</code> element with the machine readable ISO8601 datetime or date as the value

==Current uses==

'''note using these formats will mean your content will likely fail WCAG2.0 accessibility'''

The pattern, which is now available as part of [[hcalendar|hCalendar]], [[hcard|hCard]] and [[hreview|hReview]], is:

:<pre><abbr class="foo" title="YYYY-MM-DDTHH:MM:SS+ZZ:ZZ">Date Time</abbr></pre>

where foo is the semantic classname which is being applied to this date/time, the title of the <abbr> is an ISO 8601 date/time, with an appropriate level of specificity, and "Date Time" is a human-friendly representation of the same date/time.

An alternative, if you are using UTC-based timestamps, would be:

:<pre><abbr class="foo" title="YYYY-MM-DDTHH:MM:SSZ">Date Time</abbr></pre>

with a single "Z" as per [http://en.wikipedia.org/wiki/ISO_8601 ISO 8601]

== Profile of ISO8601 ==

We recommend that any [[microformat]] using the date-time-design pattern use a profile of ISO8601. There are currently two widely used profiles which SHOULD be reused.

* RFC 3339
* [http://www.w3.org/TR/NOTE-datetime W3C Note on Datetimes]

==Acessibility issues==

Ironically, this pattern while machine readable for browsers compatible with microformats is not accessible for screenreaders when referring to a date. Therefore:

<pre>
we have a party in
<abbr class="dtstart" title="20070312T1700-06">
March 12, 2007 at 5 PM
</abbr>
</pre>

would be read by jaws as

<pre>
we have a party at Twenty million seventy-thousand three-hundred twelve tee seventeen-hundred dash zero six.
</pre>

The [http://www.webstandards.org/2007/04/27/haccessibility/ acessibility task force] from web standarsd.org recommends:

<pre>
<span class="dtstart" title="20070312T1700-06">
March 12, 2007 at 5 PM, Central Standard Time
</span>
</pre>

or

<pre>
<span class="dtstart">
March 12, 2007 at 5 PM, Central Standard Time
<span class="value" title="20070312T1700-06"></span>
</span>
</pre>

see more at [[abbr-design-pattern-issues]] and [http://www.webstandards.org/2007/04/27/haccessibility/]

== Discussion ==

This pattern is likely to be highly resuable.

--[[User:RyanKing]]

Can this not be viewed as a microformat in itself?

--[[User:DimitriGlazkov]]

It could, but inventing a microformat for the sake of inventing a microformat is against the microformat principles.
If there is a specific real world problem (and uses cases) that such an elemental microformat would solve, then it would be worth considering.

Until then it is best to keep the <abbr> datetime concept merely as a microformat design pattern, to be used in _actual_ microformats that have a demonstrated practical need.

Excerpt from #microformats Aug 18th. Please edit!

<pre>
Aug 18 15:16:14 <Tantek> DanC, what do you think of RFC3339?
Aug 18 15:17:14 <Tantek> ISO8601 subset
Aug 18 15:17:19 <DanC> Date and Time on the Internet: Timestamps http://www.ietf.org/rfc/rfc3339.txt
Aug 18 15:17:30 <DanC> Klyne is a good guy. I wonder if I talked with him about this.
Aug 18 15:17:32 <Tantek> compat with W3C-NOTE-DATETIME
Aug 18 15:17:50 <Tantek> compat with xsd:dateTime
Aug 18 15:17:57 <Tantek> it's a strict intersection subset
Aug 18 15:17:59 <DanC> I consider W3C-NOTE-DATETIME obsoleted by XML Schema datatype-- yeah.. xsd:dateTime
Aug 18 15:18:32 <Tantek> compare/contrast normatively using xsd:dateTime vs. RFC3339
Aug 18 15:18:41 <Tantek> note: Atom 1.0 chose RFC3339
Aug 18 15:18:50 <Tantek> i would like input from the microformats community on this
Aug 18 15:19:27 <DanC> in what context are you evaluating RFC 3339?
Aug 18 15:19:28 <jcgregorio> http://bitworking.org/news/Date_Constructs_in_the_Atom_Syndication_Format
Aug 18 15:21:24 <DanC> which microformat is the question coming from, Tantek ?
Aug 18 15:23:31 <DanC> " The grammar element time-second may have the value "60" at the end of
Aug 18 15:23:31 <DanC> months in which a leap second occurs" The XML Schema WG is in the 27th level of
leap-second-hell for the past few months, I gather.
Aug 18 15:24:21 <DanC> yeah... here's the scary bit: " Leap seconds cannot be predicted far into the
future. The
Aug 18 15:24:21 <DanC> International Earth Rotation Service publishes bulletins [IERS] that
Aug 18 15:24:21 <DanC> announce leap seconds with a few weeks' warning."
Aug 18 15:26:03 <Tantek> DanC, which microformats? any/all that use datetime fields.
Aug 18 15:26:36 <DanC> hard to give useful advice, then.
Aug 18 15:26:58 <DanC> I expect they'll use datetime fields for different things that have different
cost/benefit trade-offs
Aug 18 15:27:26 <DanC> do you know of any particular differences that matter to anybody?
Aug 18 15:56:43 <KragenSitaker> RFC3339 suggests -07:00, which seems like an improvement over -0700 anyway
Aug 18 15:56:49 <Tantek> Kragen, agreed
Aug 18 15:57:01 <Tantek> RFC3339 is certainly preferable to the ISO8601 subset in iCalendar
Aug 18 16:05:57 <DanC> Tantek's right, Kragen; iCalendar looks like it solves the local timezone
problem but doesn't.
Aug 18 16:06:14 <DanC> and it's true that there's no standard solution to the local timezone problem
Aug 18 16:06:39 <Tantek> so instead of appearing to solve the problem but not solving it, we chose to
provide the ability to *approximate* the local timezone using e.g. "-07:00"
Aug 18 16:06:49 <DanC> the simplest thing is to have people use Z time in hCalendar. But I gather
that's unacceptably unusable?
Aug 18 16:07:35 <Tantek> DanC, yes, the simplest thing is to have everyone use UTC Z
Aug 18 16:07:38 <Tantek> However
Aug 18 16:07:50 <Tantek> it is not *nearly* as usuable/verifiable
Aug 18 16:07:55 <Tantek> as -07:00 etc.
Aug 18 16:08:02 <Tantek> hence the decision to go with the latter
Aug 18 16:08:12 <Tantek> some degree of human verifiability is important here
Aug 18 16:14:21 <Tantek> DanC, my perception is that RFC3339 is a subset
Aug 18 16:17:00 <DanC> time-numoffset = ("+" / "-") time-hour ":" time-minute
Aug 18 16:17:34 <DanC> ok, then I can't see any differences. (modulo recent leap seconds issues that
may affect xsd:dateTime )
Aug 18 16:18:07 <Tantek> would be interesting to know why Atom 1.0 chose RFC3339 over xsd:dateTime
Aug 18 16:18:21 <Tantek> if there was a "real" reason or if it was arbitrary / coin-flip.
</pre>

Here's an exhaustive [http://www.imc.org/atom-syntax/mail-archive/msg13103.html comparison] from ndw. I think xsd:dateTime also allows unqualified local times, while RFC3339 allows only UTC with no known timezone (-00:00). In the end, Atompub followed the advice of [http://www.imc.org/atom-syntax/mail-archive/msg13244.html Sam Ruby] and [http://www.imc.org/atom-syntax/mail-archive/msg13248.html Scott Hollenbeck], our area director. Atom dates make some additional restrictions on RFC3339, such as uppercase T and Z characters for compatibility with xsd:dateTime, RFC3339, W3C-DTF, and ISO8601. --[http://franklinmint.fm Robert Sayre]

<pre>
Aug 18 16:18:43 <KragenSitaker> rfc3339 is pretty short.
Aug 18 16:19:36 <Tantek> DanC, BTW, which came first? REC for xsd:dateTime or RFC3339?
Aug 18 16:19:50 <DanC> RFC3339 is dated July 2002 ...
Aug 18 16:19:54 <KragenSitaker> Right --- and you might be able to understand xsd:dateTime without
reading all of xml schema, you wouldn't be confident of it
Aug 18 16:20:25 <DanC> W3C Recommendation 28 October 2004 ... but that's 2nd ed...
Aug 18 16:20:47 <DanC> W3C Recommendation 02 May 2001
Aug 18 16:22:10 <DanC> I don't see a BNF in http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#dateTime ...
Aug 18 16:22:43 <KragenSitaker> yeah, appendix D of the current xml schema datatypes document seems
a little scanty, actually
Aug 18 16:23:28 <DanC> ah... 2nd ed of http://www.w3.org/TR/xmlschema-2/#date is much more
explicit about syntax.
Aug 18 16:23:30 <KragenSitaker> it's 1100 words but still doesn't give any examples
Aug 18 16:23:35 <DanC> still, it's given in prose and not BNF
Aug 18 16:24:17 <KragenSitaker> sections 3.2.9 through 3.2.14 seem to be the relevant ones around #date
Aug 18 16:24:29 <KragenSitaker> which is another 2200 words
Aug 18 16:24:42 <DanC> wow... they changed the canonical form of date from always-Z to
timezone-allowed between 1st edition and 2nd edition
Aug 18 16:25:01 <Tantek> Kragen, DanC, these are very good analyses
Aug 18 16:25:21 <Tantek> could I ask you to summarize the pros/cons for each in a new section at
end of http://microformats.org/wiki/datetime-design-pattern
Aug 18 16:25:22 <Tantek> ?
Aug 18 16:25:58 <KragenSitaker> rfc 3339 is 4000 words, excluding the last two pages of boilerplate.
Aug 18 16:26:31 <KragenSitaker> so it's actually longer than the datetime-relevant parts of XSD but it
seems much more rigorous and clear
Aug 18 16:28:37 <DanC> my advice is: normatively cite both, and claim they specify the same
syntax, and let anybody who discovers otherwise send you a bug report
with a test case
Aug 18 16:29:12 <KragenSitaker> danc: nice hack
</pre>

The RFC3339 has a mandatory TIME portion of the DATE-TIME. Some vCard/iCalendar DATE-TIME stamps can omit the TIME. For instance, DTSTART, if that is a full day event, then you can omit the time. BDAY in vCard can be respresented by only a DATE. I like the idea of restricting the possible date formats, but i think that TIME should be optional, which it isn't in RFC3339. - [http://suda.co.uk/ brian suda]

RFC 3339 allows lowercase 't' and 'z' while XSD doesn't. Specifying RFC 3339 plus 'T' and 'Z' MUST be caps will make them the same. - [http://bitworking.org Joe Gregorio]

---

A few questions:

1) Would it make more sense for documenting the alternative codings pitting the abbr tag vs. other tags to be on this page?

2) Would using the title attribute of the abbr tag to encode the machine-readable date in fact cause a failure of WCAG 2.0 Accessibility? What about USA Section 508? It does appear to violate Technique for WCAG 2.0 [http://www.w3.org/TR/WCAG20-TECHS/#H28 H28: Providing definitions for abbreviations by using the abbr and acronym elements], although that is a supporting document and does not have the force of a guideline.

3) In order to maintain accessibility, would it make sense to enclose the machine-readable date in a span with a style of "display:none" instead of using the abbr tag?

4) For that matter, wouldn't you want to style such an abbr tag with text-decoration:none to hide that an abbr tag was used? Otherwise, visitors might cursor over the time, see the machine time, and be annoyed that their time was wasted or else be confused. And I don't think you can suppress the title from coming up if the human-readable time was inadvertently hovered.

The following regular expression (parsed VERBOSE) should break apart a datetime and cover many lightly broken cases seen in the wild. This has been tested under Python.

<h1> Abbr design pattern </h1>

__TOC__

== Purpose ==
* Use the [[abbr-design-pattern]] to make text that is human readable also formally machine readable
* Avoiding using the [[abbr-design-pattern]] to re-encode human text or to hide data

== How to use it ==
* enclose the human-friendly text that you want to make machine readable with <code><abbr></code>
* as per the [[class-design-pattern]], add the appropriate <code>class</code> attribute to the <code>abbr</code> element
* add a <code>title</code> attribute to the <code>abbr</code> element with the machine readable data as the value

== Example ==
The [[datetime-design-pattern]] formally encodes (the notoriously unparsable) datetimes into an <code>abbr</code> element.

== Discussion ==
''This discussion is culled from [http://microformats.org/discuss/mail/microformats-discuss/2005-October/001277.html here]''. Consider two possible uses for the [[abbr-design-pattern]]:

<ol>
<li>
using ABBR to encode machine readable data around human readable data

<pre>
<abbr class="dtstart" title="20051010T10:10:10-0100">10 o'clock on the 10th</abbr>
</pre>
</li>
<li>
using ABBR to encode more formal human data around something less formal

<pre>
<abbr class="author" title="Danny Ayers">Danny</abbr>
</pre>
</li>
</ol>

Use #1 is encouraged if there's a reasonable need for it. Use #2 is discouraged under the [http://c2.com/cgi-bin/wiki?DontRepeatYourself Don't Repeat Yourself principle], as: "#2 is a case of *more* information being invisibly present, namely, the
last name in this case. If someone is not willing to make some information visible, then we
shouldn't be encouraging them to store that information invisibly, for all
the same reasons that invisible metadata is bad/futile in the first place."

''I'd like to delete this below, as the points are covered above''

* Theoretically, this could be done with almost any HTML element. But is it a good idea? If it's not, is abbr the only one? [[DavidJanes]]
* abbr-design-pattern should be avoided, if possible. [[User:RobertBachmann|RobertBachmann]]
** why, or under what circumstances? For example, it is quite useful with datetimes. Should there not be other potentially analogous situations? [[DavidJanes]]
** Under circumstances where the text in the title would be gobbledegook if read by a screenreader. JAWS and other screenreaders use title attributes from abbr, when used properly (as in this example from the WCAG group), to pronounce words which would otherwise be unreadable or confusing. Using machine data such as datetime as a title is an bending of the dictionary definition of abbreviation (contraction by ommision or initialisation, applied at the word and not semantic level), this may not be a great issue in itself, but if screen readers are unable to turn title content into something comprehensible, this will lead to accessibility failures.

<pre>
<p>Sugar is commonly sold in 5 <abbr title="pound">lb.<abbr> bags.</p>
<p>Welcome to the <abbr title="World Wide Web">WWW</abbr>!</p>
</pre>

==Acessibility issues==

Ironically, this pattern while machine readable for browsers compatible with microformats is not accessible for screenreaders when referring to a date. Therefore:

<pre>
we have a party in
<abbr class="dtstart" title="20070312T1700-06">

would be read by jaws as

<h1>hAudio 0.1</h1>

[[haudio|hAudio]] is a simple, open, distributed format, suitable for embedding information about audio recordings in (X)HTML, Atom, RSS, and arbitrary XML. hAudio is one of several [[microformats]] open standards.

__TOC__

== Introduction ==

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.

In order to enable and encourage the sharing, distribution, syndication, and aggregation of audio content, the authors propose the hAudio microformat, an open standard for distributed audio metadata. The authors have researched both numerous [[audio-info-examples]] in the wild and earlier attempts at [[audio-info-formats]], and have designed hAudio around a simple minimal schema for audio content. Feedback is encouraged on the [[haudio-feedback|hAudio feedback]] page.

=== Inspiration and Acknowledgments ===

Many thanks to the various individuals that did research and proposed ideas and discussion related to media info and audio info in general. Among the many participants are [[RodBegbie]], Dean Hudson, [http://tantek.com/log/|Tantek Çelik], Mary Hodder (http://napsterization.org/stories/), Joshua Kinberg (http://joshkinberg.com/blog/), ChrisMessina, and Lisa Rein (http://onlisareinsradar.com/).

=== Scope ===

Audio content consistently share several common fields. Where possible hAudio has been based on this minimal common subset.

==== Out of scope ====

Fields that are type-specific have been omitted from hAudio. It is important that hAudio be kept simple and minimal from the start. Additional features can be added as deemed necessary by practical implementation experience.

The concept of a universal audio identifier, that is, how to identify the same audio album, song, speech, or podcast across different music and audio sites, though something very useful to have, is outside the scope of this format.

== Semantic XHTML Design Principles ==

{{semantic-xhtml-design-principles}}

== Format ==

=== In General ===
The hAudio format is based on a set of fields common to numerous audio content sites and formats in use today on the web. Where possible field names have been chosen based on those defined by the related [[hcard|hCard]] standards.

=== Schema ===

The hAudio schema consists of the following:

* hAudio ('''<code>haudio</code>''')
** '''title'''. required. text.
** '''collaborator'''. optional. [[hCard]].
*** suggested roles: speaker, artist, composer, band, publisher
** '''release-date'''. optional. using [[date-pattern]].
** '''sample'''. optional. using rel-sample.
** '''acquire'''. optional. using rel-acquire or rel-payment.
** '''image-summary'''. optional. using img.
** '''genre'''. optional. text.
** '''length'''. optional. time in units. abbr-pattern.
** '''price'''. optional. hCurrency.

'''tracks''' and '''songs''' are denoted by embedding hAudio's inside of hAudios and using the [[collection-id-pattern]].

=== Field details ===

The fields of the hAudio schema represent the following:

The following field names have been reused from the [[hcard|hCard]] and [[hcalendar|hCalendar]] microformats: <code>version, summary, fn, url, photo, description</code>. In addition, items and reviewers described by hCards MAY contain any hCard field. The rel value "self" has been reused from the [http://atompub.org/2005/07/11/draft-ietf-atompub-format-10.html Atom 1.0 specification].

=== More Semantic Equivalents ===

For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:

* For any "url", use <code><a class="url" href="...">...</a></code> inside the element with the class name 'haudio' in hAudio.
* And for "image-summary", use <code><img class="image-summary" src="..." alt="Photo of ..." /></code>

==== Language ====

* To explicitly convey the natural language that an hAudio is written in, use the standard (X)HTML 'lang' attribute on the element with class="haudio", e.g. <code><div class="haudio" lang="en"> ... </div></code> If portions of an hAudio (e.g. the item name) are in a different language, use the 'lang' attribute on those portions.
* hAudio processors which need to handle the language of reviews MUST process the standard (X)HTML 'lang' attribute as specified.

=== Human vs. Machine Readable ===
If an <code><abbr></code> element is used for a property, then its '<code>title</code>' attribute is used for the value of the property, instead of the contents of the element, which can then be used to provide a user-friendly alternate presentation of the value.

Similarly, if an <code><img /></code> element is used for one or more properties, it MUST be treated as follows:

# For the "image-summary" property and any other property that takes a URL as its value, the <code>src="..."</code> attribute provides the property value.
# For other properties, the <code><img /></code> element's '<code>alt</code>' attribute is the value of the property.

=== Object Includes ===

hAudio includes support for the [[id-based-collection-pattern]].

=== Notes ===

This section is informative.

* By marking up audio content with the hAudio microformat, the expectation is communicated that information about the content MAY be indexed. This has no impact on the copyright of the content itself which the publisher may explicitly specify using [[rel-license]] as specified above.
* The enumerated list of item types is under development and may be extended.
* Each type may have custom hAudio fields that follow the common set.
* Additional details about a particular item should be specified with the rest of the item's info at the URL provided for the item.

== Examples ==
Here are a few examples of audio content from current web sites, and how they could be easily enhanced to support the hAudio audio metadata microformat.

Want to write valid [[haudio|hAudio]]? Use the [http://microformats.org/code/haudio/creator hAudio creator] (not implemented yet) to write about audio content and publish it on your blog.

=== 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). 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.

=== 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). 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

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** [[audio-info-brainstorming]]
** audio-info-proposal
** audio-info-microformat

AlexandreVandeSande: /* Remix */

= 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.

=== 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). 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

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** [[audio-info-brainstorming]]
** audio-info-proposal
** audio-info-microformat

== Introduction ==

Examples of what people actually publish on the Web when discussing, linking to, referring to media. This is focused predominantly on time based media such as audio and video, but may consider aspects of static media as well such as still images.

== Emphasis on Practical, Simple, and Minimal ==

Since all previous known attempts at this problem area have ended up quite complex and over-designed, this attempt will place simplicity and minimalism first and foremost.

Thus for now, this document is deliberately restricted to examples that are:
* ''Actual'' examples in practice on the Web '''with URLs''' to the originals (note, all *-examples pages should be like this, but previous attempts at documenting media info examples have mostly ignored this requirement, and thus it is necessary to be explicit).
* Representative of ''very common'' publishing behavior on the Web. This focus on common, representative examples is essential. If possible, include an estimate of the number of similar examples. E.g. ~10k.
* Simple and minimalist. As simple as possible. Go read [http://microformats.org/wiki/microformats#the_microformats_principles the microformats principles] right now before proceeding any further.

Any examples added which do not conform to these requirements will be deleted.

Any generic analysis will also be deleted. Analysis before examples is premature. Once there are sufficient media-info-examples, and hopefully a simple/clean listing of [[media-info-formats]], we'll hopefully start a [[media-info-brainstorming]] page to do aggregate analysis of the examples.

===Note on proposals===

Because the hMedia became a task so big that it seems impossible to make it "simple and minimal" discussions started on splitting them by media type.

see: [[audio-info-brainstorming]]

== Real World Examples ==

=== Overall Notes About Examples ===
These examples are organized into a short list of top level media categories, in the hopes that it will be easier to determine if there are media specific publishing behaviors, in addition to common behaviors across multiple types of media. Some may be subcategorized and distinguished by whether it was published by an individual publisher or a service:
* Audio (Speech, Music)
* Video
* Photos

The numbers after some of the examples' descriptions are based on numbers found pulling in media records at Dabble. Others may have higher numbers and would be encouraged to restate them if that's true.

=== Audio ===

==== 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 =====

=== Video ===
Publication of video on blogs often goes by "videoblogging", "vlogging", "VODcasting", or "video podcasting". The typical process involves publishing a direct link to the video file within the blog entry. The blog entry can, but does not have to, include an embedded video player. Many videos include a thumbnail jpg which is clickable to the media object and player. Some video includes links to those other source videos, photos and audio that have been quoted. Most videos have the same base elements as photos and audio, with the exception of quotes.

=== Photos ===
* A few photos online have region annotation and quoting. But as tools are developed that are usable for mass publishers, this will likely increase.
* Many videos have thumbnails that are jpgs.
* Many videos use pictures and therefore the pictures themselves are quotes from the video.
* Most photos have the same elements as videos and audio, with the exception of quotes.

== Notes on Existing Practices ==

Mary Hodder:
* We are finding as we look at thousands of user generated media records, that all have titles, creator, at least a default licensing, most have tags whose functionality is made available through the hosting service (the richer the media, the more likely tagging goes toward 100%), Html and media URLs, thumbnail URLs, publishing date, and about 25% have quoting information of some sort (quotes of video or audio, and region quotes of photos).
* Tags apparently appear at the upload point on 61% of photos in Flickr, and within a short period, 80+% have tags. 12% of users in Flickr apparently tag photos other than their own.

Manu Sporny (on music):
* There is an increasing number of sites that link to different methods of acquiring content displayed on a web page. These may include links to high-quality, or full versins of the media being described on the page. The various options include: free, streaming with ads, one-time purchase, and rental.
* Summaries, long descriptions and reviews are also prevalent in some of the content.

Manu Sporny (on video):
* We should attempt to support the basic information on sites that have been operational for years such as IMDB and Rotten Tomatoes among others. These sites tend to have very detailed information on all things related to video and TV - other sites will follow their lead because their meta-data seems to be the most complete on the web - thus making every other site contain a sub-set of their meta-data.

== Next Steps ==
# Add more real-world, simple, minimal examples.
# Research and organize existing/previous [[media-info-formats]], with a focus on formats for publishing '''common''', '''user-visible''' media information.
# Start [[media-info-brainstorming]] based on examples.

== See Also ==
* [[media-metadata-examples]] - previous attempt to catalog and organize top down metadata systems generated by engineers and committees, as examples of elements, and includes formats which should be in a separate page. Useful as a source of research but this microformat needs to embrace the bottomup ways users are publishing photos, video and audio online.

== Introduction ==

Examples of what people actually publish on the Web when discussing, linking to, referring to media. This is focused predominantly on time based media such as audio and video, but may consider aspects of static media as well such as still images.

== Emphasis on Practical, Simple, and Minimal ==

Since all previous known attempts at this problem area have ended up quite complex and over-designed, this attempt will place simplicity and minimalism first and foremost.

Thus for now, this document is deliberately restricted to examples that are:
* ''Actual'' examples in practice on the Web '''with URLs''' to the originals (note, all *-examples pages should be like this, but previous attempts at documenting media info examples have mostly ignored this requirement, and thus it is necessary to be explicit).
* Representative of ''very common'' publishing behavior on the Web. This focus on common, representative examples is essential. If possible, include an estimate of the number of similar examples. E.g. ~10k.
* Simple and minimalist. As simple as possible. Go read [http://microformats.org/wiki/microformats#the_microformats_principles the microformats principles] right now before proceeding any further.

Any examples added which do not conform to these requirements will be deleted.

Any generic analysis will also be deleted. Analysis before examples is premature. Once there are sufficient media-info-examples, and hopefully a simple/clean listing of [[media-info-formats]], we'll hopefully start a [[media-info-brainstorming]] page to do aggregate analysis of the examples.

===Note on proposals===

Because the hMedia became a task so big that it seems impossible to make it "simple and minimal" discussions started on first making separate formats: [[hAudio]], [[hMovie]] and etc by media type

== Real World Examples ==

=== Overall Notes About Examples ===
These examples are organized into a short list of top level media categories, in the hopes that it will be easier to determine if there are media specific publishing behaviors, in addition to common behaviors across multiple types of media. Some may be subcategorized and distinguished by whether it was published by an individual publisher or a service:
* Audio (Speech, Music)
* Video
* Photos

The numbers after some of the examples' descriptions are based on numbers found pulling in media records at Dabble. Others may have higher numbers and would be encouraged to restate them if that's true.

=== Audio ===

==== 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.

=== Video ===
Publication of video on blogs often goes by "videoblogging", "vlogging", "VODcasting", or "video podcasting". The typical process involves publishing a direct link to the video file within the blog entry. The blog entry can, but does not have to, include an embedded video player. Many videos include a thumbnail jpg which is clickable to the media object and player. Some video includes links to those other source videos, photos and audio that have been quoted. Most videos have the same base elements as photos and audio, with the exception of quotes.

=== Photos ===
* A few photos online have region annotation and quoting. But as tools are developed that are usable for mass publishers, this will likely increase.
* Many videos have thumbnails that are jpgs.
* Many videos use pictures and therefore the pictures themselves are quotes from the video.
* Most photos have the same elements as videos and audio, with the exception of quotes.

==== Individual Publishing of Photos ====

* We are finding as we look at thousands of user generated media records, that all have titles, creator, at least a default licensing, most have tags whose functionality is made available through the hosting service (the richer the media, the more likely tagging goes toward 100%), Html and media URLs, thumbnail URLs, publishing date, and about 25% have quoting information of some sort (quotes of video or audio, and region quotes of photos).
* Tags apparently appear at the upload point on 61% of photos in Flickr, and within a short period, 80+% have tags. 12% of users in Flickr apparently tag photos other than their own.

Manu Sporny (on music):
* There is an increasing number of sites that link to different methods of acquiring content displayed on a web page. These may include links to high-quality, or full versins of the media being described on the page. The various options include: free, streaming with ads, one-time purchase, and rental.
* Summaries, long descriptions and reviews are also prevalent in some of the content.

Manu Sporny (on video):
* We should attempt to support the basic information on sites that have been operational for years such as IMDB and Rotten Tomatoes among others. These sites tend to have very detailed information on all things related to video and TV - other sites will follow their lead because their meta-data seems to be the most complete on the web - thus making every other site contain a sub-set of their meta-data.

== Next Steps ==
# Add more real-world, simple, minimal examples.
# Research and organize existing/previous [[media-info-formats]], with a focus on formats for publishing '''common''', '''user-visible''' media information.
# Start [[media-info-brainstorming]] based on examples.

== See Also ==
* [[media-metadata-examples]] - previous attempt to catalog and organize top down metadata systems generated by engineers and committees, as examples of elements, and includes formats which should be in a separate page. Useful as a source of research but this microformat needs to embrace the bottomup ways users are publishing photos, video and audio online.

AlexandreVandeSande: /* Individual Publishing of Speech */

= 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.

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

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat

AlexandreVandeSande: /* Music Podcasting */

= 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.

=== 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 ====

==== 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.

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat

= 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.

=== 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 ====

** Appears to be composed of:
*** title/summary of the recording

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat

AlexandreVandeSande: /* Music Podcasting */

= 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.

=== 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 ====

* [http://www.microformats.org/blog/2005/09/30/web-essentials-audio/ Microformats: Web Essentials Audio]
** Appears to be composed of:
*** title/summary of the recording
*** clickable hyperlink to the recording (MP3)

So please adjust the URL manually and then visit the site.

=== Music ===

==== Individual Publishing of Music ====

* [http://www.bradsucks.net/music/ Brad Sucks » music]
** Has album title, song title, separate link to more info, inline flash player, and play link (to mp3)

* [http://www.scottandrew.com/music/ Scott Andrew - lo-fi acoustic pop superhero! > music >]

** 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)

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat

== See Also ==

* [[music-info-examples]]
* [[rel-enclosure]]
* ''Normative references for tags used''

= 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.

=== 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 ====

** Appears to be composed of:
*** title/summary of the recording
*** clickable hyperlink to the recording (MP3)
** Contextual:

So please adjust the URL manually and then visit the site.

==== Individual Publishing of Music ====

** 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)

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat

= 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.

=== 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 ====

** Appears to be composed of:
*** title/summary of the recording

So please adjust the URL manually and then visit the site.

==== 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)

== Existing Practices ==

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

===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. -- '' [[User:ManuSporny|ManuSporny]] ''
* On music service sites, the audio album is almost always described on the same page as the track listings. -- '' [[User:ManuSporny|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.

== Proposal ==

* Early drafts
** audio-info-brainstorming
** audio-info-proposal
** audio-info-microformat
