Please try again. Here's what I've done via iSQL on URIBurner: ## Load latest RDF resource that contains ontology SPARQL LOAD ; ## Add triple for merging across ontology versions with different URIs in the ABox SPARQL INSERT INTO GRAPH { owl:sameAs . } ; ## Make Rule RDFS_RULE_SET ('http://uriburner.com/inference/rules/goodrelations#', 'http://www.heppnetz.de/ontologies/goodrelations/v1.owl'); ## Use these pragmas to maximize above. DEFINE input:inference "http://uriburner.com/inference/rules/goodrelations#" DEFINE input:same-as "yes"
