Internally generated identifiers are necessary for database management,
but if I don't know the 'real' URI for something I make sure I represent
that lack of knowledge. Then I use meta-knowledge about certain predicates
(eg. 'personalMailbox','corporateHomepage') to fold together nodes that
'must' be the same because they share a property/value pair that implies
they are the self-same node...
