1) On wikipedia, we have lots of dates where only years or months are
specified Eg. the ancient Korean kingdom in this article
http://en.wikipedia.org/wiki/Gojoseon the last year of existence was
108BC. The precision is year units so judging from the examples for
whole days from the microformats book Brian edited, as well as in the
hcalendar, iCalendar (RFC2445) documents, the dtend for this date
should be -0107. Similarly, if the battle end date is given as August,
1843 then the dtend should be 1843-09, and if the article says battle
end date is August 19, 1843, then the dtend should be 1843-08-20.
Correct?
Looks OK to me. You should be aware that many parsers will not have
been tested with dates prior to 1 AD. If they're using decent ISO
8601 parsing libraries, they should probably be OK, but if they've
written their own parser for dates, they may not be safe. My own
parser <http://buzzword.org.uk/swignition/> mostly deals with such
dates OK. The following fragment is parsed correctly for instance:
<div class="vevent">
<span class="summary">The death of Julius Caesar</span> occurred on
<abbr class="dtstart" title="-0043-03-15">the Ides of March, 44BC</
abbr>.
</div>
2) hCalendar usage for death dates. Consider article Ceasar Augustus:
http://en.wikipedia.org/wiki/User:J_JMesserly/demo1. We are aware of
proposals for dday (death day) addition to hCard. Some feel vEvent is
perfectly suited to Life events. My question: Is the usage of
vevent, dtstart and dtend in this example in any way officially
deprecated or ruled improper?
hCard officially has no way of marking up dates of death. hCard's
properties are entirely taken from vCard 3.0. The IETF is currently
drawing up drafts for vCard 4.0 - it looks like this next version of
vCard will contain a property 'DDAY' for date of death. Whether hCard
is ever updated to use the new vCard standard is another question
though. However in my parser I support the proposed new vCard 4.0
properties (which also include 'BIRTH' and 'DEATH' for marking up the
places of birth and death) as an hCard extension. Until that time,
hCalendar is the only "official" way of marking up dates of death
using Microformats.
Looking at your example, it does seem a little odd to mark up
Augustus' entire life as a single hCalendar event with a start and
end date. Not strictly wrong, but unusual. A better way would be to
mark up his birth and death as separate events - this has the
advantage that you can mark up the locations of birth and death, and
even categorise the events as murder, suicide, accidental, etc.
