hi
I am experimenting with a SPARQL query, embedded in XQuery and using the
*sem:ruleset-store* functionality. The query specifies a custom ruleset in
addition to the standard "TransitiveProperty.rules" as follows:
#1:
*let $rdf-store := sem:ruleset-store(("/lims/rulesets/derivedFrom.rules",
"TransitiveProperty.rules"),sem:store((), cts:or-query(($q1,$q2))) )*
#2:
*let $rdf-store := sem:ruleset-store(("/lims/rulesets/derivedFrom.rules",
"TransitiveProperty.rules"),sem:store() )*
In the first version, the *sem:store* contains triples selected via a
*cts:query* construct; the second version the *sem:store* specifies the
entire default graph. In terms of data, the underlying RDF is such that #1
is a subset of #2.
When the SPARQL/XQuery is executed, the results generated from the two
different *sem:ruleset-store* versions are identical, except that only #2
includes the effect of applying the TransitiveProperty.rules ruleset. In
the case of #1 above, "TransitiveProperty.rules" seems not to be being
applied; remove this ruleset from #2 and the two *sem:ruleset-store*
functions produce identical results.
An explanation for this would be really helpful.
regards
-Tony
