Jim; It's really hard to say without seeing the script. I think the key here that IterateOverSelect applies a query to a set of triples and iterates the sub-script (sm:body) over the result set (not the triples), binding variables to a result set row on each iteration.
I'm not sure what you mean by "this did not appear to work", but the general technique would be to load the triples once and pass them on to the modules you need. You can use multiple sm:next edges to pass the same set of triples on to different modules, including multiple IterateOverSelect modules, each of which apply separate queries to the input triples. Let us know if that helps... -- Scott On May 11, 1:54 pm, James A Miller <james_a_mil...@raytheon.com> wrote: > Scott, > > I was trying to improve the performance of my multiple-spreadsheet ingest > script in SparqlMotion. > > I am importing several fairly large OWL files, which are combined with the > spreadsheet OWL data, and then using Construct to construct the triples > that I need.
