aside -

FOAF was designed to work with RDF. It could be squeezed into
Microdata but as I understand it, would look butt-ugly since property
names would be things like http://xmlns.com/foaf/0.1/openid

I'm not anti-Microdata btw. The item* terminology is quite nice, for
example. But I wouldn't want to recommend people encode FOAF in it
without deciding on a namespace URI abbreviation mechanism...
