Vote on this: rel="me self" to indicate an authoritative hCard {was: Re: [uf-discuss] Authoritative hCards [was RE: Canonical hCards (was: Search on CSS element)]}

[digital spaghetti]

Just chiming in my two pence here:

Rather than something like @rel="me self", would a better idea not be
to look at including some kind of way of authenticating the source
such as a MicroID hash?

This has already been discussed on the MicroId list along the lines of this:

@rel="me microid-mailto+http:sha1:hash" (has being a full sha1 or
sha256 hash), then services like claimID can then look at the tag, and
convert back.  If your registered ClaimID email address and the URI of
the source match the hash in the rel tag, then the source is verified
as being you?

There are more details on the spec at http://microid.org/microid.html
