Re: [topbraid-users] SPARQLMotion IterateOnSelect examples
If a magic property is not resolving, have you tried renaming its file
to something like .spin.ttl - this should have the system register all
SPIN functions and magic properties globally.

should add that all of the graphs that are needed are imported into
the SM script and resolve in the imported graphs tab in SM.

Depending on your setup, SWP might be a better choice for such

[topbraid-users] SPARQLMotion IterateOnSelect examples
I have a question. Does anyone have an example of an IterateOverSelect that
has a body that performs an insert on the results of the IterateOverSelect
variables?
My Intent: execute a IterateOnSelect SELECT that produces multiple rows of
several bindings, use body of IterateOnSelect to INSERT each row
sml:selectQuery:
SELECT ?a ?b ?c
WHERE {
something related to input argument .
}
sm:body:
INSERT {
qname, label, and properties of qname
}
WHERE {
something using ?a, ?b, and ?c
create unique qname and labels
}
sm:next:
Do something with the items that were inserted by the sm:body
But the IterateOverSelect never seems to get executed (at least, I cannot
see it binding ?a, ?b, or ?c and no insertions are performed.
The SPARQL MOTION library reference has no examples.
