We have talked before about auto-discovery of microformatted data,
and about describing vcards at the other end of a link. Here is the
notes so far, it hasn't been talked about in awhile, so feel free to
read-up and add your notes.
There is also an article about "Authoritative Metadata" which details
the fallbacks of where the browser/server is first suppose to gather
data about the resources, then where too look next if it fails. This is
important because we can start sticking things in rel="vcard" or
possibly use the 'a' element TYPE attribute. So you could have:
<a href="http://example.org/my.vcf" rel="something here vcard me"
class="something here maybe" type="text/x-vcard">my vcard</a>
This doesn't always work because the TYPE attribute has to describe the
resource, but hCards are embedded in HTML, so you couldn't cite them
directly unless your link was to a web service that transformed the HTML
to a vCard.
I hope this helps the discussion about auto-discovery, because this
could be used across all microformats, hAtom, hReview, hCalendar, etc.
