I have recently started learning Web Ontology Language (OWL). I want to define a DataProperty with my own defined range of value. Consider the following property: <owl:DatatypeProperty rdf:ID="myProperty"> <rdfs:domain rdf:resource="#MyDomain"/> <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#double"/> </owl:DatatypeProperty> The property has the range of double value but I want to restrict the range in order to make my property to accept only double values between 0 and 1. I would be very grateful if you guide me how to define my own ranges for data properties. Here you go (in
