	(The definition of "know" here is very broad. It is if you sat down next
	to that person on a train, you would know their name if they introduced
	themselves to you, and they would know your name.) 

Wondering whether this is a good gloss for foaf:knows

Also brings up the question (discussed in IRC recently) about whether we
say that foaf:knows is symmetrical, ie.
whether ?x foaf:knows ?y can be possible without ?y foaf:knows ?x.
Intuitively I find this quite appealing, but it has sensitive corner
cases (eg. alzheimers)...
