I am attaching a script that looks as in the screenshot:
You need to make sure that the PerformUpdate specifies the target
graphs, using the GRAPH keyword. Otherwise it doesn't know where the
triples shall go.
The Merge step is just there as a dummy placeholder for some module that
handles the result graph.
Depending on your setup, SWP might be a better choice for such
SPARQL-based transformation scripts.

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.
Thank you...
Jack
