This is getting perilously close to the reason for RDF...

I would suggest that rather than the willy-nilly approach that
OSM uses (horse=yes) we try as far as possible to use tags
that can be mapped easily to RDF predicates.

Proposal #1: Tags SHOULD be of the form "prefix:tag" where
prefix is the usual well-known prefix that would be used in
an RDF/N3 serialisation.

Proposal #2: Have a special prefix, "prefix" to explicitly define
prefixes to be used elsewhere in the record. So you might have,

    dc:description=Some description

#2 might prove a bit awkward in practice though.

Is it time to start looking at ripping out the SQL back-end and
replacing it with an RDF store? Is there anyone that is
interested in helping to do this? If we could keep as much of
the user-interface code as possible it shouldn't be too hard.
