Josh Ellis writes asking whether there’s utility in being able to take one’s personal email filtering rules, export them to a standard XML format, and then point new/other email clients at them.
Seems to me this is another example of what Bill Burnham and, earlier, Dan Bricklin, have been talking about. In Dan’s case, his SMBmeta proposal was designed to enable small businesses to post content and pointers to information about their companies using a standardized format. Seems like what Josh is thinking of could be a component of a “PERSONALmeta” proposal – where individuals keep data, information, rules, etc. that’s their own.
In a world where everyone has a website, this seems like a natural conclusion. Maybe OpenID fits in here too?
