Really good to see this work!

May be nothing, but...it appears the tagging date is associated with
the tag. I assume most systems would want to infer that tags with the
same meaning were equivalent (even though this isn't specified using
IFPs or whatever). I'm a little concerned about what you'll get when
merging different doc's data with this assumption of equivalence -

<doc1> ctag:tagged [
   a ctag:Tag
   ctag:taggingDate "2009-06-12"
   ctag:means <http://rdf.freebase.com/ns/en/collaborative_tagging> ] .

<doc2> ctag:tagged [
   a ctag:Tag
   ctag:taggingDate "2009-06-13"
   ctag:means <http://rdf.freebase.com/ns/en/collaborative_tagging> ] .

->

 [  a ctag:Tag
   ctag:taggingDate "2009-06-12"
   ctag:taggingDate "2009-06-13"
   ctag:means <http://rdf.freebase.com/ns/en/collaborative_tagging> ]

- which doesn't look very useful.

Or am I misreading the intention?

Cheers,
Danny.
