Some people want a little, some people a lot. I conducted some experiments on metadata last year involving bribing people with cake in exchange for metadata. Even offering people free cake still led to poor metadata.

It's not as remixable as raw content, but as an exchange format - then it probably has potential for wider use than providing LOM or DC by themselves.

Yeah.
I guess it's all a bit chicken and egg, too - if no one is going to use
it, doesn't matter what format, but then if it isn't in a recognisable
format, no one is going to use it.
Dangling carrots didn't work, then? Even carrot cake.
