             Summary: Implement support for owl:unionOf inference
                 Key: RYA-293
                 URL: https://issues.apache.org/jira/browse/RYA-293
             Project: Rya
          Issue Type: Sub-task
            Reporter: Jesse Hatfield


An *{{owl:unionOf}}* expression defines one type to be equivalent to the union 
of another set of types. If the ontology states that {{:Parent}} is the union 
of {{:Mother}} and {{:Father}}, then the inference engine should rewrite 
statement patterns of the form {{?x rdf:type :Parent}} to check for resources 
that are stated to be any of the types {{:Mother}}, {{:Father}}, or {{:Parent}}.
