> An *{{owl:hasSelf}}* restriction defines the set of resources that are connected to themselves by a specific property.
> If the ontology states that a {{:Narcissist}} is a resource that {{:loves}} itself, then the inference engine should:
> 1. Rewrite queries of the form {{?x rdf:type :Narcissist}} to find all resources matching {{?x :loves ?x}} (as well as anything explicitly stated to be a :Narcissist) .
> 2. Rewrite queries of either form {{:A :loves ?y}} or {{?z :loves :A}} to match {{:A}} if {{:A}} is known to have the type {{:Narcissist}} .
