As you know, no end-user is going to type in any of the following into a
Username or Account capture input field:
1. mailto:xyz at example.com
2. acct:xyz at example.com.
What they will type in is: xyz at example.com.
Where "mailto:", "acct:", and "http:" come into play is back-end
handling via service specific heuristics . Google have made a commitment
to dealing with the "acct:" via GMAIL service. AOL has also followed
suit. Methinks that's ample re. uptake on the data space provider front.
We are doing the same re. WebID such that we can perform public key &
identifier matches irrespective of what identifiers we pick up in the
X.509 cert. I don't see any reason for sticking with HTTP URIs solely.
As I continue to project, my preference is for the more semantically
rich approaches to succeed based on their intrinsic merits. This is
ultimately how they will reach mass usage. Basically, back to my old
"embrace and extend" (in a positive way) mantra :-)
I am a middleware guy, data model and data representational disparity
are simply facts of computing life to me.
