In de “Ceci n’est pas un FAQ” over de nieuwe machine tags van Flickr (zie ook alhier), schrijft Aaron Straup Cope onder meer dit.

# Is the predicate *really* a predicate?

You are in a dark cave. In the corner is a fire and a man making bunny shadows on the wall with his hands. Whether or not it’s really a ‘predicate’ depends on how much time you spend on the semantic-web mailing list. 😉

It’s close enough to being a predicate that it makes for a good short-hand.

# Wait, aren’t machine tags just RDF?

No, machine tags are not RDF; they could play RDF on television, though.

# Huh, what is RDF ?

RDF Describes Flickr. That’s really all you need to know about RDF.

Ik moet daar dus heel erg hard om lachen. 😀
