did you look at http://usefulinc.com/foaf/signingFoafFiles ?

the weaknes of the approach is that it is not actually signing rdf but a
file, so its hard to aggreagte personal profiles and retain the
signature. but the pgp approach of mutulal key-signing is certainly much
more foaf-like than to have identies confirmed by a ca [1].

But when someone else wants to make use of it, how can he trust that the informatiion is true? i don't know wheather it is a good idea to build a kind of CA to authenticate the FOAF information. Sometimes it is very hard to say the information is true or not, for example someone said in his FOAF file that he believes in Christianism, and i am looking for persons with same faith, how can i trust his words?
