One thing that is working its way up to daylight is a standardized way
(or ways) to ask an RDF server to cough up all the information it knows
about a given subject. This gives you a starting point for exploring
the remote and possibly distributed data store without having to just
get a dump (which might end up being huge). It's actually quite
feasible today. See URIQA, for example, which was worked out by Patrick
Stickler of Nokia -
