== 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.

=== 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 =====

** Examples: [http://musicbrainz.org/browseartists.html browse] and [http://musicbrainz.org/search.html search] the catalog

=== 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.

==== Individual publishing of video ====

* [http://FreeVlog.org FreeVlog]: the most popular tutorial on the web describing the videoblogging process by combining free tools and services (Blogger, OurMedia/Internet Archive, FeedBurner).
** According to this process, a videoblog entry contains:
*** Direct link to the video file
*** Clickable thumbnail image/screen capture of the video
*** Contextual information about the video (title, description, etc) is usually contained in the surrounding blog entry

* [http://joshkinberg.com/popupmaker Video Pop Up Maker]
** This example based on the process taught at [http://FreeVlog.org FreeVlog] generates code to create a dynamic pop up window with embedded video player. The reasons for this are enumerated [http://www.unmediated.org/archives/2005/10/easily_create_p.php here]

=== 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 ====
* [http://blog.bouckenooghe.com/2005/09/01/em6-a-est-fache-avec-le-centimetre/ Blog A Brac » E=m6 a est fâché avec le centimètre - photo with annotated screen-caps]

* [http://scribbling.net/projects/fotonotesrolloverviewer/fotonotesplugin.php?p=helicopterovernyc.jpg Scribbling.net implementation of Fotonotes Plugin demonstrating the fotonotes annotation tool for photos]
** This example has media url, quotes and descriptions, creator. +200 across all individually blogged photos.

* For more work along the lines of 2d annotations, please see (and add to) [[photo-note-examples]].

==== Service publishing of photos ====

* [http://www.flickr.com/photos/500hats/50282408/ Flickr - Photo Sharing instance of a photo.]
** This example has a Title, Html URL, media URL, description or summary, quotes URLs and descriptions, licence, tags, upload time, playlist (set), license, creator, and other capture data. +millions across all hosters. +millions of records.

** This example has a Title, Html URL, creator, licence, link to creator's other photos. Three alternate download sizes, link to buy a print. Link to add as favorite. Link to next, previous photos in collection. Photo belongs to generic category (no tags). Links to related photo searches.

== 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.

== 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.

NateAune: /* MusicBrainz */

This is an exploratory page to be used for storage of various multimedia data and metadata profiles, formats, and practices currently in use around the web. As this is a very, very early exploration, we should include as many types of multimedia as possible in the opening discussion - but please be sure to place your information in the correct portion of this page.

= Purpose of this exploration (or : The Problem) =

The purpose of the studies on this page is to determine the feasibility and demand for a flexible, semantic markup format for multimedia related paradigms.

This includes such things as:
<ul>
<li>Providing metadata alongside linked multimedia files.Typically, multimedia metadata is stored within the header of the media file itself - which has massive implications for any application where metadata is to be indexed, searched, or made externally accessible. Of course, even if you could easily access the correct portions of a media file remotely, you'd still have to cope with a multitude of open and proprietary metadata formats, each with it's own distinct fieldset, nomenclature and storage method.
</li>
<li>What is called: Internet TV, IPTV, [http://newtube.org/ NewTube], vlogging, vidblogging, vidlogging, vodcasting, etc.</li>
<li>What is called: Podcasting, IPradio, etc.</li>
</ul>

This study aims to make a start at solving this problem.

Below is a list of strawman models based on real work examples. (Links to actual examples have been omitted since many of them have been found on adult sites, and it is believed that it would be inappropriate to list these here. -- [[User:Charles|Charles]])

=== Show Strawman #1 ===
Single clip with a preview image. The clip is the full show.
<nowiki>
<a href="clip.mpeg"><img src="preview.png" /></a>
</nowiki>

=== Show Strawman #2 ===
Single clip with a preview image. The clip is the teaser of the
full show. And there is a link that you can go to pay to see the full
show.
<nowiki>
<a href="teaser.mpeg"><img src="preview.png" /></a>

<a href="http://example.com/go">Pay to View</a>
</nowiki>

=== Show Strawman #3 ===
A show divided up in multiple clips, each with a preview image.
Together the clips make up the show.
<nowiki>
<a href="clip-1.mpg"><img src="preview-1.png" /></a>

<a href="clip-2.mpg"><img src="preview-2.png" /></a>

<a href="clip-3.mpg"><img src="preview-3.png" /></a>
</nowiki>

=== Show Strawman #4 ===
A set of teasers for a show. Together they don't make up the full
show. And the may or may not overlap in time. There's a "Pay to
View" link there too.
<nowiki>
<a href="clip-blue.mpg"><img src="preview-blue.png" /></a>

<a href="clip-red.mpg"><img src="preview-red.png" /></a>

<a href="clip.ogm">Ogg</a>
<a href="clip.avi">AVI</a>
</nowiki>

=== Show Strawman #6 ===
A single preview image with the show given in 2 different methods. The first is the show broken up into a series of pieces (which makes it easier to download.) And the second is the full show in one file
<nowiki>

</nowiki>

=== Show Strawman #7 ===
A single clip with a preview image. The title of the show is given with an image (and thus the actual machine-readable title is the ''alt attribute'' of the image) and is linked with the main URL for the show. There's also a link to older episodes of the show.
<nowiki>
<a href="..."><img src="the-name-of-the-show-png" alt="The Name of the Show" /></a>

<a href="older-shows">older shows</a>
</nowiki>

=== Show Strawman #8 ===
A series of clips with preview images. The title of the show is given with an image (and thus the actual machine-readable title is the ''alt attribute'' of the image) and is linked with the main URL for the show. There's also a links to older and news episodes of the show.
<nowiki>
<a href="..."><img src="the-name-of-the-show-png" alt="The Name of the Show" /></a>

</nowiki>

=== Show Strawman #9 ===
A series of preview images. The title of the show is given in text. A link to all the show's files via a torrent. Other metadata is also typically included too, in plain text; some is shown here. Also, sometimes metadata is put in the description.
<nowiki>

iTunes release 4.9 was widely heralded as an advance for mainstream acceptance of podcasting. However, while some advocates resist even the fragment of a trademarked name in the label for the phenomenon, the use of "itunes:" in the namespace is one of many design decisions in Apple's original specification that became focal points of debate. While Apple has a tradition of working on breakthrough features very quietly, they have been open to public input after its initial release. Many [http://daringfireball.net/2005/07/podcast_pocket other bloggers] have [http://usefulinc.com/edd/blog/contents/2005/06/28-rss-apple-itunes/read chronicled] [http://www.intertwingly.net/blog/2005/07/05/Insensitive-iTunes some of the feedback], as well as some [http://tantek.com/log/2005/07.html#d10t0130 face-to-face discussions].

=== A Podcasting Microformat? ===

The best starting point for understanding these two proposals is [http://www.w3.org/2005/07/media-and-rss W3C's summary table, by Karl Dubost].

There are (at least) two paths to consider when 'porting' these proposals into Microformats:
# '''Standalone.''' What is the most straightforward rendering of each proposal into XHTML? This keeps the interests of the developers of ''consuming'' applications foremost: how can the migration be made as painless as possible?
# '''Refactored.''' Given the existing core of Microformats, what is the minimal (!) necessary to add on to RelLicense, RelTag, hReview, and so forth? This favors (we'd hope) content ''publishing'' applications: how can the marginal migration costs of adding media be made as painless as possible.

Mapping the existing specs requires understanding the data definitions set forth in each specification, and finding the optimal equivalents (where available). The following is a partial summary of one possible mapping:

== Container Formats ==
The purpose of container formats is to allow the muxing of multiple codecs into a single file or stream. For example, if you want audio, video, and text (subtitles) combined into a single stream.

The purpose of the muxing is for synchronization and so that you can stream the file and view it without having to jump around -- seek -- in the file.

Container formats include:
* AVI
* MPEG
* Ogg
* QuickTime

=== Notes for Microformats ===
One of the problems with container formats is that it is often difficult and sometimes impossible to know the disposition of what they contain ahead of time (without reading the file).

For example, Ogg files use the MIME type application/ogg and generally use the extension .ogg. With only these 2 pieces of information, you cannot tell whether such an Ogg file contains video data or not.

There is room for a microformat to help with this. Perhaps something like:
<div style="font-family:monospace;white-space:pre;padding:1.5em;background-color:black;color:white;"><a class="moving-image" type="application/ogg" href="my.ogg">...</a></div>
Although, this can be done in other ways too. For example, using [http://changelog.ca/log/2005/08/21/rss-disposition-hinting-proposal disposition hinting] one could do something like:
<div style="font-family:monospace;white-space:pre;padding:1.5em;background-color:black;color:white;"><a type="application/ogg;disposition-type:moving-image" href="my.ogg">...</a></div>

Anothing thing for any Microformat to consider is that it may be the case that the data files that are muxed in the container format may also be offered in non-muxed forms. This is important when alternatives are offered.

== Audio Formats ==

Audio formats include:
* AAC
* MP3
* PCM WAV
* Speex
* Vorbis
* WMA

=== Audio Format Comparison Table ===

<table border="1" cellpadding="5" cellspacing="0" style="border:1px solid grey;">

=== Notes for Microformats ===
* Knowing whether audio data is streamable or not can affect pre-fetching. And can be a metric used when alternatives of the same file is given.
* Having audio data marked as lossy or lossless can be useful when alternatives of the same file is made.

This is an exploratory page to be used for storage of various multimedia data and metadata profiles, formats, and practices currently in use around the web. As this is a very, very early exploration, we should include as many types of multimedia as possible in the opening discussion - but please be sure to place your information in the correct portion of this page.

= Purpose of this exploration (or : The Problem) =

The purpose of the studies on this page is to determine the feasibility and demand for a flexible, semantic markup format for multimedia related paradigms.

This includes such things as:
<ul>
<li>Providing metadata alongside linked multimedia files.Typically, multimedia metadata is stored within the header of the media file itself - which has massive implications for any application where metadata is to be indexed, searched, or made externally accessible. Of course, even if you could easily access the correct portions of a media file remotely, you'd still have to cope with a multitude of open and proprietary metadata formats, each with it's own distinct fieldset, nomenclature and storage method.
</li>
<li>What is called: Internet TV, IPTV, [http://newtube.org/ NewTube], vlogging, vidblogging, vidlogging, vodcasting, etc.</li>
<li>What is called: Podcasting, IPradio, etc.</li>
</ul>

This study aims to make a start at solving this problem.

Below is a list of strawman models based on real work examples. (Links to actual examples have been omitted since many of them have been found on adult sites, and it is believed that it would be inappropriate to list these here. -- [[User:Charles|Charles]])

=== Show Strawman #1 ===
Single clip with a preview image. The clip is the full show.
<nowiki>
<a href="clip.mpeg"><img src="preview.png" /></a>
</nowiki>

=== Show Strawman #2 ===
Single clip with a preview image. The clip is the teaser of the
full show. And there is a link that you can go to pay to see the full
show.
<nowiki>
<a href="teaser.mpeg"><img src="preview.png" /></a>

<a href="http://example.com/go">Pay to View</a>
</nowiki>

=== Show Strawman #3 ===
A show divided up in multiple clips, each with a preview image.
Together the clips make up the show.
<nowiki>
<a href="clip-1.mpg"><img src="preview-1.png" /></a>

<a href="clip-2.mpg"><img src="preview-2.png" /></a>

<a href="clip-3.mpg"><img src="preview-3.png" /></a>
</nowiki>

=== Show Strawman #4 ===
A set of teasers for a show. Together they don't make up the full
show. And the may or may not overlap in time. There's a "Pay to
View" link there too.
<nowiki>
<a href="clip-blue.mpg"><img src="preview-blue.png" /></a>

<a href="clip-red.mpg"><img src="preview-red.png" /></a>

<a href="clip-green.mpg"><img src="preview-green.png" /></a>

<a href="http://example.com/go">Pay to View</a>
</nowiki>

=== Show Strawman #5 ===
A single clip that comes in different formats. (Could be a
teaser, a clip, or a full show.)
<nowiki>
<img src="preview.png" />
<a href="clip.mpg">MPEG</a>
<a href="clip.ogm">Ogg</a>
<a href="clip.avi">AVI</a>
</nowiki>

=== Show Strawman #6 ===
A single preview image with the show given in 2 different methods. The first is the show broken up into a series of pieces (which makes it easier to download.) And the second is the full show in one file
<nowiki>
<img src="preview.png" />

<a href="part-1.mpg">[1]</a>
<a href="part-2.mpg">[2]</a>
<a href="part-3.mpg">[3]</a>

<a href="full.mpg">full</a>
</nowiki>

=== Show Strawman #7 ===
A single clip with a preview image. The title of the show is given with an image (and thus the actual machine-readable title is the ''alt attribute'' of the image) and is linked with the main URL for the show. There's also a link to older episodes of the show.
<nowiki>
<a href="..."><img src="the-name-of-the-show-png" alt="The Name of the Show" /></a>

<a href="episode123-clip.mpeg"><img src="episode123-preview.png" /></a>

<a href="older-shows">older shows</a>
</nowiki>

=== Show Strawman #8 ===
A series of clips with preview images. The title of the show is given with an image (and thus the actual machine-readable title is the ''alt attribute'' of the image) and is linked with the main URL for the show. There's also a links to older and news episodes of the show.
<nowiki>
<a href="..."><img src="the-name-of-the-show-png" alt="The Name of the Show" /></a>

<a href="episode123-clip.mpeg"><img src="episode123-preview.png" /></a>

<a href="newer-shows">[next]</a>
<a href="older-shows">[previous]</a>
</nowiki>

=== Show Strawman #9 ===
A series of preview images. The title of the show is given in text. A link to all the show's files via a torrent. Other metadata is also typically included too, in plain text; some is shown here. Also, sometimes metadata is put in the description.
<nowiki>

However, while some advocates resist even the fragment of a trademarked name in the label for the phenomenon, the use of "itunes:" in the namespace is one of many design decisions in Apple's original specification that became focal points of debate. While Apple has a tradition of working on breakthrough features very quietly, they have been open to public input after its initial release. Many [http://daringfireball.net/2005/07/podcast_pocket other bloggers] have [http://usefulinc.com/edd/blog/contents/2005/06/28-rss-apple-itunes/read chronicled] [http://www.intertwingly.net/blog/2005/07/05/Insensitive-iTunes some of the feedback], as well as some [http://tantek.com/log/2005/07.html#d10t0130 face-to-face discussions].

* '''Media RSS:''' http://search.yahoo.com/mrss

Media RSS has [http://www.ysearchblog.com/archives/000111.html been in the works longer], but doesn't have the overnight-adoption advantage of iTunes. However, it has a much broader ambit, including [http://www.ysearchblog.com/archives/000060.html video]; and a much broader [http://groups.yahoo.com/group/rss-media/ community of interest].

=== A Podcasting Microformat? ===

The best starting point for understanding these two proposals is [http://www.w3.org/2005/07/media-and-rss W3C's summary table, by Karl Dubost].

There are (at least) two paths to consider when 'porting' these proposals into Microformats:
# '''Standalone.''' What is the most straightforward rendering of each proposal into XHTML? This keeps the interests of the developers of ''consuming'' applications foremost: how can the migration be made as painless as possible?
# '''Refactored.''' Given the existing core of Microformats, what is the minimal (!) necessary to add on to RelLicense, RelTag, hReview, and so forth? This favors (we'd hope) content ''publishing'' applications: how can the marginal migration costs of adding media be made as painless as possible.

Mapping the existing specs requires understanding the data definitions set forth in each specification, and finding the optimal equivalents (where available). The following is a partial summary of one possible mapping:

== Container Formats ==
The purpose of container formats is to allow the muxing of multiple codecs into a single file or stream. For example, if you want audio, video, and text (subtitles) combined into a single stream.

The purpose of the muxing is for synchronization and so that you can stream the file and view it without having to jump around -- seek -- in the file.

Container formats include:
* AVI
* MPEG
* Ogg
* QuickTime

=== Notes for Microformats ===
One of the problems with container formats is that it is often difficult and sometimes impossible to know the disposition of what they contain ahead of time (without reading the file).

For example, Ogg files use the MIME type application/ogg and generally use the extension .ogg. With only these 2 pieces of information, you cannot tell whether such an Ogg file contains video data or not.

There is room for a microformat to help with this. Perhaps something like:
<div style="font-family:monospace;white-space:pre;padding:1.5em;background-color:black;color:white;"><a class="moving-image" type="application/ogg" href="my.ogg">...</a></div>
Although, this can be done in other ways too. For example, using [http://changelog.ca/log/2005/08/21/rss-disposition-hinting-proposal disposition hinting] one could do something like:
<div style="font-family:monospace;white-space:pre;padding:1.5em;background-color:black;color:white;"><a type="application/ogg;disposition-type:moving-image" href="my.ogg">...</a></div>

Anothing thing for any Microformat to consider is that it may be the case that the data files that are muxed in the container format may also be offered in non-muxed forms. This is important when alternatives are offered.

== Audio Formats ==

Audio formats include:
* AAC
* MP3
* PCM WAV
* Speex
* Vorbis
* WMA

=== Notes for Microformats ===
* Knowing whether audio data is streamable or not can affect pre-fetching. And can be a metric used when alternatives of the same file is given.
* Having audio data marked as lossy or lossless can be useful when alternatives of the same file is made.

== Quicktime Broadcaster Notes ==

For setting up a mac laptop with an iSight and QT Broadcaster in order to publish live audio/video from events.

# Make sure you have the necessary equipment and software installed
#* A Macintosh running OSX 10.3.9 or later
#* Quicktime 7 - get it from http://www.apple.com/quicktime/
#* Quicktime Broadcaster - get it from http://www.apple.com/quicktime/broadcaster/
#* An iSight or digital video camera with firewire connection
# Get a broadcast template document from someone (see KevinMarks for example)
# Open that, then change the info in the 'Network' pane that has his name etc in it.
# Check the video and audio panes are using your iSight
# Another tip is that the standalone thingy for the iSight can be more useful than the screen-top one if you have a desk, as that way it picks up less typing noise and wobbles
# I find plugging in headphones is a good idea, as you can then monitor and not get howlround
