Right on.

I think we can really benefit from some discovery
mechanism rather than being limited to the blind

Or just links to full cards that match a search.

Drift is always going to be an issue. "Cool URLs don't

What I am after is a way to represent distributed
datasets (paginated listings and various related
items) with uFs.  A REST style service will often
provide some listing (hopefully XOXO):

GET /contacts

  <a href="/larry#hCard" title="Larry" class="disco-hCard">Larry</a>
  <a href="/moe#hCard" title="Moe" class="disco-hCard">Moe</a>

Follow a link in the listing to get a full editable

GET /larry#hCard

[ Larry's hCard ]

Parse and edit larries info then PUT it back.

PUT /larry/#hCard

[ Larry's modified hCard ]

Sorry for getting so hypothetical. I promise to
write a formal problem statement and start
gathering examples strait away, if there is
interest. :-)

Does anyone else feel that this is worth getting
started on the wiki?
