I love RDFa. RDFa is cool. If you haven’t tried it, try it, you’ll like it – its just a really simple way to embed RDF statements in a valid HTML doc using a couple properties like about= and rel= and property=. Check out the primer which is pretty well written and published last October at http://www.w3.org/TR/xhtml-rdfa-primer/

But, I have a gripe. You’re supposed to be able to name anything, I mean anything by assigning it a URI so you can talk about it in RDF. You can name your dog, your coffee cup, the moon, any idea that can be put into words and enclosed in two html tags – but you can’t name a bit of RDF in any meaningful way using RDFa.

See, I thought you could do a nifty thing like assign an id= property to the tag that starts a statement, then you could say things about the statement like “I agree with that”; “I don’t agree”; “whoever believes that statement should go live with the penguins for a month” or whatever. But you can’t. I have it on really good authority, that you can’t. I’ve already griped to the people in charge so now I’m complaining to you. Ok, I feel better – thanks for listening. You aren’t gonna charge me, right?
