But then I remembered a wonderful little thing called FOAF+SSL that binds a Person Entity URI to an X.509 Cert. that is then exported to a Browser and usable across the Web as a WebID. This very WebID is the conduit to the profile of the person who is issuing the query. So yet again, we have a real world problem and the dexterity of HTTP URIs to the rescue :-) -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
