Additionally,
I would like to create new property of xsd:boolean type for skos:Concept.
I need that the property has false value by default.
I created field with:
rdf:type: rdf:Property
rdfs:domain skos:Concept
rdfs:range xsd:boolean.
I added sh:defaultValue property and set it to false.
But in evn default value hasn;t been appeared.
So, Is it possible to add new property with default value?
