I've studied it in some depth.  There's a free trial download available from
their Web site that's well worth a look; it's got a very clean interface.
Written in Java, and highly portable.  Personal edition only at the moment,
and I suspect they'll have problems scaling the current system up to
enterprise levels.

They also have a patent on the underlying storage model --- quite an
interesting patent to read, as it concerns how to expose a triples model and
still get tolerable performance by storing sets of related triples.  I'm
still musing on whether there's prior art.

That's the same claim as for any other triple store... one table for node
definitions, one for arcs.  It's like the comparison between multiple CSV
files versus XML as data transfer mechanisms --- you get more flexibility
using XML.
