Re: How to store numerics or dates as values in Accumulo?
Would it be best to store such values in some a canonical lexical format
with a postfix of the datatype URI, kind of like the Turtle RDF format does
this?

"10"^^<http://www.w3.org/2001/XMLSchema#integer>
"-12.5e10"^^<http://www.w3.org/2001/XMLSchema#double>
"2012-12-21"^^<http://www.w3.org/2001/XMLSchema#date>

Also, does anyone know of Accumulo being used as an RDF triple store?  Any
links to projects or resources would be welcome.  It seems like a pretty
good fit.
