hCard history and extensions (was Re: [uf-discuss] Date of Death in hCard)

I don't believe that hCard needs to be extended to accommodate a  
"date of death" field. I think that we already have a microformat to  
deal with this use case; it just doesn't happen to be hCard.

The dtend field in hCalendar seems like the perfect fit for this.  
Microformats are intended to be embeddable within one another: an  
hCalendar within an hCard (or visa-versa, depending on how you look  
at it) allows for all the desired information to be marked up:

<p class="hcard vevent">
   <span class="fn summary">Charles Darwin</span> was
   born on <abbr title="1809-02-12" class="dtstart bday">February 12,  
   and died on <abbr title="1882-04-19" class="dtend">April 19,1882</ 

Because there is a way of marking up this information using existing  
microformats, I see no reason to extend hCard.

It's a similar situation with genealogy. I don't think there's any  
need for a genealogy microformat because the required information can  
already be marked up using a combination of hCard, hCalendar and XFN:
