there was a long thread about it last April, you can read through the archives:

i don't think much was agreed upon, but ideas were certainly floated.

The way i quickly find things in the archives is by using Google's
SITE: search parameter.

"site:microformats.org/discuss/ death day"


You might want to try searching for other things like "date of death"
ect. That discussion might have spanned a few threads?

Do paintings have a published range? i thought you could only PUBLISH
it once. I can see books being republished, but then we increment the
EDITION. dtpublished changes for second edition.

In your case you are actually asking for a fuzzy precision, like this
photo was taken "last week" or "last year". At the moment there is no
way to indicate this very well, and i'm not sure DURATION is the exact
semantics you would be looking for this this situation, although i
don't have anything more to offer.

The other source of inspiration is "What are consuming apps doing?"
are they looking for a string "73.7 cm" or are they looking for some
sort of object, "int for length" 73.7,"type of dimention" height,
"enum for unit" cm? If that is the case, then each should be
explicitly marked-up, if not, then a string is fine and you don't need
to deal with UNITS explicitly. It kinda goes back to the question of
"Are we solving an existing problem, or are creating a problem to be
