Figured rather than using the other list this might be the best place to
ask/show a Podcast feed. Figured it might get derailed like the last
discussion on Podcasts.

Anyway, at the moment got a very early version of a directory listing
for all BBC Podcasts, which can be found here:
http://downloads.bbc.co.uk/podcasts/ppg.xml

What am looking for is some feed back on this really, and possibly what
people would like to see included in here.

The current version on live is missing an "rssenc" element which would
give information about the files in a Podcast. This is element would
work as follows:
<rssenc 
 
type="audio/mpeg|audio/x-m4a|video/mp4|video/x-m4v|video/quicktime|appli
cation/pdf"
    medium="image|audio|video|document|executable" 
    stream="true|false"
    audioEnc="mp3|wma|acc"
    audioProfile="ABR|CBR|VBR"
    videoEnc="x264|mpeg4|mpg2|mpg1|wvc1|..."
    videoProfile="ABR|CBR|VBR"
/>

So, for a typical MP3 Podcast it would be:
<rssenc type="audio/mpeg" medium="audio" stream="false" audioEnc="mp3"
audioProfile="CBR" />

For AAC Enhanced Podcast:
<rssenc type="audio/x-m4a" medium="audio" stream="false" audioEnc="aac"
audioProfile="VBR" />

What I would like to also add for the next version (apart from the
"rssenc" element) is information on the current episode in the Podcast
(if there is one). This would mean you wouldn't have to parse every RSS
feed to find those with an episode (or to find the current episode). The
original idea was to just use the "link" element I already have but
extend it so that it has optional elements "title", "description" and
"pubDate". This would produce something like this:

<link target="currentEpisode"
url="http://downloads.bbc.co.uk/podcasts/radio4/archers/archers_20071018
-1920.mp3">
        <title>Archers: Thursday 18 Oct 07</title>
        <description>Jazzer gives Ed some words of advice, and Lynda
receives a surprise visitor at Ambridge Hall.</description>
        <pubDate>Thu, 18 Oct 2007 19:20:00 +0000</pubDate> </link>

Only thing I don't like about this (hence part of the reason for this
post) is that it doesn't seem (to me) to appear to be in the correct
place. The good thing about this is that it keeps everything consistent
with the schema we have. The bad/ugly is that the information about the
encoded file is not included in the "link" element. Personally think it
should be moved inside the "rssenc" element, but wondering if there is
any opinions about this and where it should probably be found?

Again, feed back on this feed would be most appreciated. Also, please
remember this is a first version and so there is a good chance that it
will change as it evolves.

P.S.

Sorry if this arrives twice, thought I had signed up to this list but
turns I hadn't so re-subscribed and sent this again.
