Correction: the representative hCard may not represent the author of the page. For example, the representative hCard on the Wikipedia entry for Julius Caesar would normally be an hCard for Julius Caesar. But Julius Caesar is not the author of the page. The representative hCard is the contact information for the person or organisation that the page is supposed to, in some way "represent". > Back to the robot ... it looks for the representative hCard and finds > it.

In which case the robot is wasting time and bandwidth if it needs to download Bob's page. So if Alice's page has an hCard with a UID property set to the same URL as the target of the XFN link, this hCard may be used instead. -- Toby A Inkster BSc (Hons) ARCS [Geek of HTML/SQL/Perl/PHP/Python/Apache/Linux] [OS: Linux 2.6.17.14-mm-desktop-9mdvsmp, up 2 days, 17:58.] The Semantic Web http://tobyinkster.co.uk/blog/2008/03/09/sw/ _______________________________________________ microformats-discuss mailing list microformats-discuss@microformats.org http://microformats.org/mailman/listinfo/microformats-discuss
