Podcasting originated as a feature of RSS, but as the world moves to the new standard Atom format, podcasters will too. Atom can support podcasting through the element. As is the case with RSS 2.0 based podcasts, you can only have one podcast per entry. But, with Atom you can have a different representation for each language and for each content-type. For example, if you want to make a podcast available in both English and German and in both MP3 and WMV formats, you can do it by adding links like those below to the entries in your feed:

   <link href=”http://example.com/podcasts/show001-usenglish.mpg” 
       hreflang=”en-US” length=”21472922” type=”audio/mpg” />

   <link href=”http://example.com/podcasts/show001-usenglish.wmv” 
       hreflang=”en-US” length=”23889921” type=”audio/wmv” />

   <link href=”http://example.com/podcasts/show001-german.mp3” 
       hreflang=”de-DE” length=”20032879” type=”audio/mpg” />

   <link href=”http://example.com/podcasts/show001-german.wmv” 
       hreflang=”de-DE” length=”19907766” type=”audio/wmv” />

Disclaimer: Atom is a work in progress (but nearly complete). This is based on Atom format draft 08. Atom experts: did I get something wrong in the above example?
