The query syntax is built upon selection criterions.

This is an example on how to get all the locations of a thing during a
time period:

$thing->arc( pred => location, valid_during => $date_range )->obj

It can be represented in RDF by using a variable namespace. Those
resources could/will also be of type "use all matching alternatives".
It cold look like this:

X -- rdf:type --> rdf:Statement
X -- rdf:type --> L:Variable
X -- rdf:predicate --> L:location
X -- L:validDuring --> L:dateRang52
X -- rdf:subject --> L:myThing42
X -- rdf:object --> Y
Y -- rdf:type --> L:Variable

And then you will say that you are intrested of all the possible Y.
That could be part of the question metadata.  Let's say that the above
is grouped as the model L:question1.  Then we could say:

L:question1 -- rdf:type --> L:Request
L:question1 -- L:searchDeapth --> '100'
L:question1 -- L:retrieve --> Y
L:question1 -- L:agent --> L:registredUserNo18
L:question1 -- L:session --> L:session985


Something like that...
