Phil; The IterateOverSelect module will accumulate triples to pass to the next module. One way to do what you want is to construct all of the triples before sending them to Oracle. If you set replace=true on the ApplyConstruct, then only the triples that you construct (in that module) will be accumulated on each iteration. When the next is executed, the triples passed will be the accumulated set of constructed triples from that IterateOverSelect. The next module would save the accumulated triples to Oracle.
If my description hasn't been clear, Exercise 4 of the SPARQLMotion tutorial addresses IterateOverSelect and replace=true, p. 21 in particular. -- Scott On Jun 3, 7:30 am, [email protected] wrote: > I am writing a sparqlmotion script that iterates over a series of XML > files containing drug data.
