OK, you are right, that wasn't so bad. Perhaps I will take a closer look at SPARQL one of these days.
BTW how does it do with things like spatial constrains.
In relational databases it's easy to express spatial joins over relations. For example given
Structure(id, name, x, y, type)
you can query for things like all the structures of type 'pharmacy' within 1 km of a 'hospital'. It's simple to define functions like distance(x1,y1,x2,y2) that may be predicated on. Anything like that in SPARQL (yet)?
