I think a category element could be useful, but I have a few questions first:
It's widely-deployed in practice,
Where?
Well, it turns out, hardly at all. I just went through a selection of a couple of dozen feeds selected from those I subscribe to, including representatives of several major blogging engines, RSS 0.9/1.0/2.0, also some big commercial publishers like the NYT and BBC.
My findings:
- more than half have no category information at all
- of those that do, almost all are using dc:subject
- I saw exactly *one* instance of RSS's <category> element, in feeds produced by Roller
So... options are:
1. put in category somewhat as I proposed it, on the grounds that it's been specified before and it's fairly clean
2. don't put in category, on the grounds that it's not been deployed
3. don't put in category but recommend the use of dc:subject
Opinions? -Tim
