Scott,
Thank you for your reply. I am using Composer and I was doing what you
mentioned above. I cant seem to get composer's sparql to acknowledge
the sameas link.
here are my steps.
I've created the following rule on the Rules view:
Body:
sioc:UserAccount(?x) sioc:UserAccount(?y) (?x sioc:last_name ?z) (?y
sioc:last_name ?z) notEqual(?x, ?y)
Head:
(?x owl:sameAs ?y)
I run the inferencing and see that there are 5 updated triples in the
Inferences view all with the predicate "owl:sameAs"
I see that my target IRI is the subject and has an object pointing to
another IRI
I go to the SPARQL view and type in the following query: (I have the
"Use Currently Configured Inferences" enabled)
SELECT *
WHERE {
?owner sioc:owner_of ?owns
}
now when I review the triples that result from this I see that my
target IRI displays its explicit "owner_of" objects but it does not
show the "owner_of" objects for the IRI that it has as its object in
the owl:sameAs relationship.
Any thoughts?
Thanks.
