Description

DESCRIBE queries need to be implemented.

While this can just return a value of "Pink fluffy elephants", something more intelligent will be better.

I am thinking of taking the DESCRIBE variable ($d), and adding the following to the WHERE clause:

AND

(($d $predicate $value AND
$predicate <rdf:label> $property)
OR
($d $property $value MINUS
$property <rdf:label> $label))
AND
$value <rdf:type> <rdfs:Literal> in <sys:type>

This shows all literal properties, using labels for the predicate where possible, and URIs when not.

Feedback showed that most people just want property/value pairs for a subject. This was in release 2.0.0.
