There are two angles to this - one is the number and sheer size of the
controlled vocabularies available, and the other is the means to place
references to them into feeds. The first doesn't necessarily cause
problems in the second.

For example it would be possible to refer to the DMOZ.org  "Movies"
category by its URI, i.e.
 http://dmoz.org/Arts/Movies/ . No need to bring in the whole of the
DMOZ vocabulary.

There's a marvellous example of what can be done in the FOAF Output
plugin for WordPress [1]. I got it installed (easy!) and here's a bit
of my RSS feed:

<item rdf:about="...">
...
	<dc:subject>General</dc:subject>
	<dc:subject>Blogging</dc:subject>
	<dc:subject rdf:resource="http://dannyayers.com/archives/author/site-admin/skos.rdf#c1"/>
	<dc:subject rdf:resource="http://dannyayers.com/archives/author/site-admin/skos.rdf#c6"/>
...

The first couple of dc:subjects associate the fairly uncontrolled
categories of "General" and "Blogging". But the next couple of
dc:subjects /are/ controlled, associating the item through dc:subject
with an identified resource, which correspond to concepts in "Danny's
Own Controlled Vocabulary".  If you take a look at
http://dannyayers.com/archives/author/site-admin/skos.rdf there's an
RDF schema, auto-generated from my categories setup.

It would be possible to use dc:subject with existing controlled
vocabularies in this fashion, but the plugin takes it a step further,
creating a personal contolled vocab. Very cool.

Cheers,
Danny.
