Hi all,
I was wondering if there is a way to manipulate “recordsets” when
building a spin:construct
I am not sure if I am doing this in the proper way. Since I have not
found “For each” functionality in SPIN, I am trying to create
different queries using different filters that require count() and
group by to create different constructs based on the data in the
“recordsets” and this is not possible following the message “Aggregate
expression not legal at this point”
To help understand my problem, I have a class called State that
relates to another class called StateRestriction via a particular
property. This relationship defines the restriction criterion for each
State as defined below.
pmda:State a owl:Class .
pmda:StateRestriction a owl:Class .
pmda:hasRestriction rdfs:domain pmda:State .
pmda:hasRestriction rdfs:range pmda:StateRestriction .
pmda:restrictionSequence rdfs:domain pmda:StateRestriction .
pmda:restrictionOpenBracket rdfs:domain pmda:StateRestriction .
pmda:restrictionOnProperty rdfs:domain pmda:StateRestriction .
pmda:restrictionType rdfs:domain pmda:StateRestriction .
pmda:restrictionValue rdfs:domain pmda:StateRestriction .
pmda:restrictionCloseBracket rdfs:domain pmda:StateRestriction .
pmda:restrictionConjunctionDisjuntion rdfs:domain
pmda:StateRestriction .
I already create a construct that creates a restriction class for each
instance of the pmda:State.
Now I need to create the Intersections and Unions of the restrictions
that are defined as many instances of the pmda:StateRestriction for
each pmda:State.
This requires me to deal with a list of State Restrictions that are
related to a unique State and I am really not sure how to do that.
Thanks in Advance,
Guil
