Product design is a secondary problem.
For real-world semantic/RDF graphs, the operating rule of thumb is
that current technologies become useless at around 100k nodes for lack
of scalability. That is single-workstation in-memory scale. There are
a number of companies offering semantic graph engines and customers
insensitive to interface with large buckets of cash for a decent graph
database but no one is crossing that chasm.

You almost never see these two things together. In the few cases where
I have, I always have the nagging feeling that I am looking at
separate manifestations of some common principle we haven't figured
out. Like I said, idle speculation.
