It's roll of dice. SPARQL comparison of RDF literals of different types
is not specified, the exception is comparison of RDF literals of
different numeric types.
I intend to improve it, well, some day, but I should warn that it will

Hi Hoan,
You can create your own Quad Map Storage for loading your RDFView into or use
the virtrdf:DefaultQuadStorage location used by the conductor when creating
RDFViews as detailed at:

Hi,

('2007'^^xsd:gYear > '2007-01-01'^^xsd:date)
('2007'^
