My question was more regarding a particular instance: Is there
something special to do to enable OWL entailement and not only RDFS
one on a virtuoso cluster ?
(Using the isql console)
Thanks
Alex.
Here is the sequence:
--- Rules Management
-- Remove
rdfs_rule_set (rule_name, graph_name, 1)
-- Add
rdfs_rule_set (rule_name, graph_name)
Example:
-- Remove
rdfs_rule_set ("music_ontology", "http://purl.org/ontology/mo/";, 1)
-- Add
rdfs_rule_set ("music_ontology", "http://purl.org/ontology/mo/";) .
You have remove and reload to ensure rule name and graph bindings are
intact. After that, it either something is going wrong or you need to
apply transitivity option to your sparql etc..
Post your sample SPARQL if your issue remains.
