[RDF] QDS

[Stefan Andersson]

Naah. I meant the [] and {} niftiness.

Maybe something like

AndBag -- subClassOf --> Bag
OrBag -- subClassOf --> Bag

MyQuery -- Criterion --> Criterion1
Criterion1 -- type --> AndBag   
Criterion1 -- _1 --> Criterion1a
Criterion1 -- _2 --> Criterion1b

Criterion1a -- type --> Negated
Criterion1a -- type --> OrBag
Criterion1a -- _1 --> Criterion1a1
Criterion1a -- _2 --> Criterion1a2

Criterion1b -- rdf:type --> partial_statement_query
Criterion1b -- rdf:predicate --> phone_number
Criterion1b -- rdf:object --> SomeNumber

Ummm... not very clear example, but maybe I got the point thru?
