Yep, fyi, Edd Dumbill has done a little guide to PGP-signing FOAF 
profiles [1]. Note the caveat:

[[
Of course, anyone can concoct a fake PGP key with your email address, 
just as they can lie about who was the |dc:creator| of a file. What 
makes the PGP signature useful is that PGP public keys hook into a web 
of trust, so you can decide how much you trust what a person with 
such-and-such a key asserts.
]]

Signing alone almost certainly isn't the whole solution, but one piece 
in a greater puzzle.

Cheers,
Danny.
