Adding this here for posterity: It seems like the primary objection to RDR is
vendor lock in. Its a BlazeGraph specific thing and would have to be
reimplemented if we had to go someplace else. You *can* trigger it
automatically using standard RDF reification

There is support for inline UUIDs for blank nodes. See UUIDBNodeIV. You
could also define a fully inline URI with a well-known prefix and a UUID.

One of the things that @Thompsonbry.systap and I talked about yesterday was
representing statements kind of like this:
wd:Q23 wdt:P39 wd:Q11696 . -- Optional
wd:Q23 wd:P39 wd:Q11696
wdqual:P580 1789-4-30T00:00:00Z^^xs:dateTime ;
wdqual:P582

You can use URIs instead of blank nodes. Most of the time when people use
blank nodes they SHOULD be using URIs. Blank nodes are existential
variables. Coin URIs if you want to have a reference.

The RDR inlining of reified statement models is handled by the
StatementBuffer class. It is important

Currently, we have two known issues with our RDF vs. BlazeGraph:
1. Date values (aka 13 billion BCE)
2. Geopoints notation
