> *{{owl:hasValue}}* is used to define a property restriction representing the
> set of resources with a specific value for a specific predicate.
> If the ontology states that the class {{:ChildOfJohn}} represents all
> resources with {{:parent}} equal to {{:John}}, then the inference engine
> should be able to:
> 1. Rewrite a query pattern {{?X rdf:type :ChildOfJohn}} to check for
> resources whose {{:parent}} is {{:John}} (in addition to those explicitly
> stated to have type {{:ChildOfJohn}})
> 2. Rewrite a query pattern {{:Jane :parent :?Y}} to check whether :Jane has
> the type {{:ChildOfJohn}} (in addition to querying for any specifically
> stated {{:parent}} s)
