Thanks Chime!
That would be typical of an optimization strategy anyway, whether manual
or automated, right?
I see some doc about Jena's query optimization at
http://jena.apache.org/documentation/query/explain.html . If anyone can
point me to similar pages for other SPARQL query processors, I'd
appreciate it.
Thanks,
Bob

If the implementation evaluates the patterns in the order you provide
(rather than determine an optimal evaluation strategy independent of
the structure of the given query), I think it does make sense.

Since OPTIONAL clauses have no chance of reducing the search space for
their containing graph pattern, does it make sense as a general rule of
thumb to put them after all the ones that do, i.e. after the
non-OPTIONAL triple patterns?
