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. -- http://danny.ayers.name
