There is very little difference between a database with three columns,
and a true triplestore ("full semantic web thing") apart from the fact
that the former has lots of RDF:s magic inherently available to it.
Which, incidently, is already coded up in librdf.
As I said before, librdf contains database-backed triplestores, RDF
query parses, and more. All one needs to do is glue it together with an
indexer.
