Hello, 

I am trying to use rdf lib to create the following: (a protege screenshot 
in the attachment)

  <Class rdf:about="http://www.abc#Building";>
        <rdfs:subClassOf rdf:resource="http://www.abc#PhysicalLocation"/>
        <rdfs:subClassOf>
            <Restriction>
                <onProperty rdf:resource="http://www.abc#hasFloor"/>
                <allValuesFrom rdf:resource="http://abc#Floor"/>
            </Restriction>
        </rdfs:subClassOf>
        <rdfs:comment>This is a type for BUILDING facilities 
object</rdfs:comment>
        <rdfs:label>Building</rdfs:label>
    </Class>
    


But the only way I am able to create something are restrictions on 
properties and not classes such as:

<owl:ObjectProperty rdf:about="http://www.abc#hasFloor";>
  <rdfs:domain rdf:resource="http://www.abc#Building"/>

  <rdfs:subPropertyOf rdf:resource="http://www.abc#hasPhysicalLocation"/>

  <rdfs:range>
    <owl:Restriction rdf:nodeID="N73e2705103db4e57b37b969e7a1d4780">
      <owl:onProperty rdf:resource="http://www.abc#hasFloor"/>

      <owl:allValuesFrom rdf:resource="http://www.abc#Floor"/>

    </owl:Restriction>
  </rdfs:range>
</owl:ObjectProperty>


Using the following code:



restriction_floor = Restriction(
    constants.NS.hasFloor,
    allValuesFrom=constants.NS.Floor,
    graph=graph)
Property(
    has_floor,
    graph=graph,
    domain=constants.NS.Building,
    range=restriction_floor)


I would like to be able to create the restriction at the subClassOf level, how 
is it possible to do this?


Thank you

Best


Charbel
