> How does RDQL handle reified properties? Nested sub-queries?
There is no explicit syntactic support in RDQL for reification - it just
relies on the fact reification statings are encoded in RDF. There has a
suggestion using a 4-tuple {x, s, p ,o} to be a shorthand for writing out
(?x rdf:type rdf:Statement)
(?x rdf:subject ?s)
(?x rdf:predicate ?p)
(?x rdf:object ?o)
As and when and if the working groupd starts up, use cases (descriptions of
use in an application example) on things like reification will be very
helpful.
