I see some interesting concepts worth exploring here, e.g. using windows
(with paging inside the window). But as I refine my query, there isn't any
apparent context that orients me in the data. E.g. how does one box/set
relate to the others.

I notice you're using Sesame, do you think it can scale? I tried selecting
several repositories at once, but the system seems to hang awhile (couple of
minutes)  before returning results.
