- Example: The following KReSRule code:
myOnt = <http://kres.iksproject.eu/myOnt.owl#> . rule1[ has(myOnt:hasParent, ?x1, ?x2) . has(<http://kres.iksproject.eu/myOnt.owl#hasSibling >, ?x2, ?x3) . has(myOnt:hasSex, ?x3, <http://kres.iksproject.eu/genders.owl#male>) -> has(myOnt:hasUncle ?x1, ?x3) ]
is equivalent to this SWRL
<swrl:Variable rdf:ID="x1"/> <swrl:Variable rdf:ID="x2"/> <swrl:Variable rdf:ID="x3"/> <ruleml:Imp> <ruleml:body rdf:parseType="Collection"> <swrl:IndividualPropertyAtom> <swrl:propertyPredicate rdf:resource="http://kres.iksproject.eu/myOnt.owl#hasParent"/> <swrl:argument1 rdf:resource="#x1" /> <swrl:argument2 rdf:resource="#x2" /> </swrl:IndividualPropertyAtom> <swrl:IndividualPropertyAtom> <swrl:propertyPredicate rdf:resource="http://kres.iksproject.eu/myOnt.owl#hasSibling"/> <swrl:argument1 rdf:resource="#x2" /> <swrl:argument2 rdf:resource="#x3" /> </swrl:IndividualPropertyAtom> <swrl:IndividualPropertyAtom> <swrl:propertyPredicate rdf:resource="http://kres.iksproject.eu/myOnt.owl#hasSex"/> <swrl:argument1 rdf:resource="#x3" /> <swrl:argument2 rdf:resource="http://kres.iksproject.eu/genders.owl#male" /> </swrl:IndividualPropertyAtom> </ruleml:body> <ruleml:head rdf:parseType="Collection"> <swrl:IndividualPropertyAtom> <swrl:propertyPredicate rdf:resource="http://kres.iksproject.eu/myOnt.owl#hasUncle"/> <swrl:argument1 rdf:resource="#x1" /> <swrl:argument2 rdf:resource="#x3" /> </swrl:IndividualPropertyAtom> </ruleml:head> </ruleml:Imp>
