Hi All,

Hoping for a little bit of guidance here on tagging & assigning subjects 
to content etc - I can't quite grasp how to describe what an item of 
content is about; particularly in the context of a normal blog post and 
with relation to tags/subjects/moat/commontag/scot etc.

In short I've build a little mashup of a few services and some linked 
data which extracts terms & subjects from an item of content; and now 
I'm unclear of which ontologies to use.


The info I can extract is "tag string" and mainly a dbpedia uri for the 
tag (to give it real meaning I guess)

example..
	string:	Nuclear program of Iraq
	URI:	http://dbpedia.org/resource/Nuclear_program_of_Iran

also bearing in mind that I'll typically have 5-10 of these per "post".

On the face of it I'd assume I should be using the following for each 
"tag" and leaving the string literal value out of the triples altogether
	http://purl.org/dc/terms/subject
	http://www.holygoat.co.uk/owl/redwood/0.1/tags/taggedWithTag

however, with MOAT/CommonTag/SCOT (and no doubt others) added in to the 
equation I'm totally lost as which is the most fitting and widely 
recognised for tagging content in this manner; is it worth adding 
something to say that it was automatically tagged by a machine? or 
including the string literal value of the tag(s)?

Many thanks in advance,

Nathan
