Hugh,

Where does one start browsing?  I haven't been able to find an  
example object.
For each one, do you have RDF URIs for (a) a typical thing example  
described by the database, and (b) a central or starting-point thing  
from which I would expect to be able to find everything there?

If I browse that, I don't know where to start.
