Hi Kingsely,
Thanks for the kind reply. It works for me. I guess I was confused that
subProperty should be transitive instead of making the target property a
subproperty of a transitive property.
Thanks.

select ?s ?p ?o from where {
?p rdfs:subPropertyOf* :PropB.
?s ?p ?o.
};
```
But still it does not return anything.
I am not sure if the query is valid in SPARQL or there is something I miss
in Virtuoso.
If there is anything that I can learn about, please let me know.
Th
ery without any inferences.
Furthermore, RDFS does not have an assumption of using OWL (transitive
property).
If it is the only way, I will add the inference rule for the convenience,
but just want to leave a note that it's an unexpected behavior.

?s :relation1 ?o.

```
This returns two tuples.
Let me know if it's still unclear.
Thank you!

Hi Kingsley,
I put * path modifier, which should also match no subClassOf relationship
pattern in my understanding.

Correction:
The current transitive relationship is commented out (which returns partial
results) and the line without transitive relationship is uncommented (which
return all results as I expected.)

ne and uncomment the second line, it returns the correct
result with the two pairs. I believe those two queries should return the

Is this a bug or do I misunderstand something in the SPARQL?

Btw, equivalentClass is working. My code was looking for a different graph
than the graph the rules were applied.

Just to provide my use case,
I presumed if there is a graph like
```turtle
ex:a rdf:type sch:Class1 .
sch:Class1 owl:equivalentClass sch:Class2 .
```
. a query like this should work
```sparql
select ?s where {
?s rdf:type sch:Class2 .
}
```
Thanks!

What is the exact keyword to use owl:equivalentClass like ``DEFINE
input:same-as "yes"``?
2. And if I use inference instead of transitive search like
``rel:ancestorOf+``, is it faster?
Thank you!

Hi Hugh,
I will try that. Thanks for the suggestion!

it does not use the same index as contains.

Hi Sergey,
Yes, your suggestion works for me. I do not know which between Virtuoso and
Jena is following the correct semantics of SPARQL, but I will follow the
more constrained (~=precise) semantics of Virtuoso.
Thank you!

Forgot to clarify the configuration:

Virtuoso 7.2.4.2
Virtuoso Jean: virt_jena3

The value ``results`` is empty and this code does not print anything. I can
make a regenerator. Let me know if that helps.

can force indexing "name" properties in Virtuoso.
