I'm thinking, at the moment, of avoiding hCard completely in the
letters themselves, basically to avoid all the horrible issues of
ambiguity and irregularity of names. For example, where Flinders
signs this letter 'Matt'w Flinders'
I'll just mark that link up using rel="tag", where the tag URL points
to the biography currently at
then use hCard to mark up Flinders as a person on that page. I think
what I'm saying is have one hCard per person on the site, which is
the biography page, then link to those hCards as tags within the
letters. That seems a lot easier than faffing around with citations
and different types of hCard.

Thinking out loud here - I'm not hugely concerned about a definitive
biography, as long as the relationships between documents at
different URLs are clearly defined. For instance, suppose I have a
biography, and hCard, for Flinders at /tags/people/Matthew_Flinders.
I could have a link from that page to http://en.wikipedia.org/wiki/
Matthew_Flinders and mark it rel="me" to indicate that the two URLs
describe the same person.
If my biography links to a letter, and that link says rel="creator",
then I think it's reasonable for a parser to infer, from the rel="me"
link, that http://en.wikipedia.org/wiki/Matthew_Flinders also
describes the creator of the letter. I don't think I need to state
that my hCard is definitive, only that it's equivalent to the one at
I suppose it would be interesting to have a mechanism to mark up
equivalence in general, not just for people. For example, to link the
description of Boston
to the wikipedia page for Boston
using whatever the equivalent of rel="me" would be for places. Ditto
for pages describing vessels, if the vessel has a wikipedia page.
Then, a letter tagged with a link to the short description of Boston
would, indirectly, also be tagged with the wikipedia description, as
well as being linked back to all references to that place in the
