We expect we want interop with LDP to work with some other systems,
and we expect that while the core of the data model will be mostly
fixed, it will change enough and there will be sorts of misc. data
that justify having a triplestore.

The question is whether or not we can find a mature triplestore that
also lets us store the data in Postgre and has acceptable performance,
with bonus points for LDP conformance.

Thanks for the pointers everyone!
