Yes, exactly as Stian says :)  There have been many, many tagging
ontologies over the years -- it's such a simple concept that people
roll their own rather than reuse existing ones.  Tagging is a use case
for Open Annotation, especially as it's an easy one to fulfill... with
this one semantic tag/document URI exception!

Yep.  And to cut to the bottom...

Yes. Our SemanticTag class would go on <term1> in the example above.
A mapping document, or wiki section, would go a long way towards
making the spec more usable I think.  This would be good for
CommonTag, Annotea, various annotation APIs such as flickr, and so

I think that there's now general consensus about everything other than
the literal body case, which as per the wiki page, really seems
unsolvable other than additional implementer experience.    So a last
once over the spec and it'll replace the current version in core later
today :)

Thank you *everyone* for all of your efforts in getting us to the
stage we're at now.  It's very rare that I have heard any
specification called "beautiful" and it would not be were it not for
your thoroughness and constructive criticism. Paolo and I greatly
appreciate it, and look forwards to continuing to work closely and
collaboratively towards additional documentation including tutorials,
the cookbook, mappings as above and so forth.
