Paul; First, it is the case that the asserted + inferred triples is
the result of running the ApplyOWLIM module. However, when you do
that, the rdfs:subClassOf inferences will be made. Your filter will
then filter out triples you hadn't before.
For example, let's say you start with:
1. :Matriarch rdfs:subClassOf :Person
2. :Person rdfs:subClassOf owl:Thing
3. :MyWife a :Matriarch
4. :Me a :Person
A variant of your filter is:
CONSTRUCT {
?a a ?type .
?a ?b ?c .
}
WHERE {
?a a ?type .
?a ?b ?c .
FILTER (?type != :Matriarch) .
}
In scenario A; the output would be triple 1 and 4.
If you then run OWLIM, you add the triples:
5. :Matriarch rdfs:subClassOf owl:Thing
6. :MyWife a :Person
The filter will now catch all of the instances, :MyWife in this case,
that have been inferred to be members of classed other
than :Matriarch. Hence there are no results to pass on to the next
module.
