Yes, we used a bogus 'genid:' URI scheme in the first FOAF files to
indicate invented URIs for people (back when the general consensus
didn't allow HTTP names for real world things, and RDF/XML didn't have
rdf:nodeID), so for eg. in
http://svn.foaf-project.org/foaftown/2010/allfactoids/copies/libby/webwho.xrdf
Libby would write <misc:knowsWell web:resource="genid:poulter"/>.
Nobody claims this as good practice, but that's how we started. Things
soon after moved to using indirect identification via unambiguous
properties; if http-range-14 had been defined and resolved by then,
we'd probably have gone straight to 'real'  URIs.
