	Currently, most programs utilize screen scrapers and partial downloads to detect file type and format information. For example, Songbird will guess a file type by parsing the file extension. Items such as bitrate and number of audio channels are retrieved from the header of the file, which must be downloaded from the server. Doing so creates a burden on the server when the information could just as easily be embedded in the HTML code for the website.		Currently, most programs utilize screen scrapers and partial downloads to detect file type and format information. For example, Songbird will guess a file type by parsing the file extension. Items such as bitrate and number of audio channels are retrieved from the header of the file, which must be downloaded from the server. Doing so creates a burden on the server when the information could just as easily be embedded in the HTML code for the website.

			Right now, we seem to have two proposed approaches to the problem:

			Example markup:

			The Gorge - MPEG video (22MB, MP3 192Kbps audio, MPEG-2 video)

			1. Use the 'type' field in the anchor element for file format, example:
			<pre>
			<a type="video/mpeg; audio-codec=MP3,
			audio-codec-sample-rate=192Kbps, video-codec=MPEG-2"
			length=23068672
			href="/angels_arete.mpg">The Gorge - MPEG video</a>
			(22MB, MP3 192Kbps audio, MPEG-2 video)
			</pre>

			2. Create a file-format uF, example:
			<pre>
			<div class="hFileFormat">
			<a href="/angels_arete.mpg">The Gorge - MPEG video</a>
			(<abbr class="size-in-octets" title="23068672">22MB</abbr>,
			<span class="audio-codec">MP3</span>
			<abbr class="audio-codec-sample-rate" title=192000>192Kbps</abbr>
			audio, <span class="video-codec">MPEG-2</span> video)
			</div>
			</pre>
