Re: Atom and RDF

r> How's this as a hypothetical RSS module:

r> <rss:item>> 
r> <rss:title>Ian's Bad Poem</rss:title>
r> <encl:enclosure rdf:resource="http://example.com/torrent"
r> dc:format="application/x-bittorrent"  <!-- whatever -->
r> dc:title="Bit torrent link to mp3" />
r> <encl:enclosure rdf:resource="http://example.com/mp3"
r> dc:format="audio/mpeg"
r> dc:title="MP3 of me reading my poem" />
r> <encl:enclosure rdf:resource="http://example.com/text"
r> dc:format="text/plain"
r> dc:title="My poem itself" />
r> </rss:item>

Yeah, something like that.

But the problem still persists: how the software will determine that these
three links point to the same content but in different representation? There
should be something like multipart/alternative MIME stuff:

<rss:item>
   <rss:title>Ian's Bad Poem</rss:title>
   <encl:enclosure type="multipart/alternative">
       <encl:enclosure rdf:resource="http://example.com/torrent"
          dc:format="application/x-bittorrent"  <!-- whatever -->
          dc:title="Bit torrent link to mp3" />
       <encl:enclosure rdf:resource="http://example.com/mp3"
          dc:format="audio/mpeg"
          dc:title="MP3 of me reading my poem" />
       <encl:enclosure rdf:resource="http://example.com/text"
          dc:format="text/plain"
          dc:title="My poem itself" />
   </encl:enclosure>
   <encl:enclosure rdf:resource="http://example.com/anothermp3"
      dc:format="audio/mpeg"
      dc:title="MP3 of me singing in bathroom" />
</rss:item>

Now I can setup my hypotetical aggregator to automatically download either
only text/plain content, or, if it's not possible, only show the link to
resource.
