The TransitiveProperty.rules rule is looking for a triple in your ontology of
the form:
?p a owl:TransitiveProperty .
Are you sure that the cts:query you pass in matches the document that contains
these ontological triples? If not, the rule won't get triggered.

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.
