Thanks, Jeff. I'll get that running. Does the service run simply over
test data, or does it make use of the vocabularies in the PREFIXs for
defined domains and ranges? As I recall, SPARQL doesn't do any
inferencing, but will it pay attention to domains and ranges inherent in
the ontology? (I've mainly used SPARQL with data that has been acted on
with a reasoner.)
If my question doesn't make sense, I'll just test it out when I get some
data created, and have gone back over the SPARQL documentation.
