Yeah, I don't see that being a tenable proposition when we're talking
about identities.  I'm not sure where the "RDF triples last until the =

entropic heath death of the universe" assertion comes from, but I really
question if that's valid reasoning.  Probably the semantic web experts =

have spent more time thinking about this stuff than I have, but that =

just does not seem realistic.  I can see saying "a triple stays valid
until the entropic heat death of the universe OR until superceded" maybe.

Seems like it should work out in practice anyway though. If I go out
and pull down a FOAF file and load it into a reasoner, I'm not going
to literally cache those triples in memory (or anywhere else) forever.
In fact, for many classes of problems, it seems like you'd go get the
FOAF/RDF once, reason on it, then throw it away, fetching it again when
needed.


TTYL,
