owl class `ComponentProperty` is a subclass of `rdf:Property`

Hi, in https://github.com/UKGovLD/publishing-statistical-data/blob/ede5e32affb236e4939b09fc63a27cdfc5d2a833/specs/src/main/vocab/cube.rdf is the following in line 110:

<rdfs:Class rdf:about="http://purl.org/linked-data/cube#ComponentProperty">
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Class"/>
    <rdfs:label xml:lang="en">Component property (abstract)</rdfs:label>
    <rdfs:subClassOf rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Property"/>
    <rdfs:comment xml:lang="en">Abstract super-property of all properties representing dimensions, attributes or measures</rdfs:comment>
    <rdfs:isDefinedBy rdf:resource="http://purl.org/linked-data/cube"/>
  </rdfs:Class>

This line suggests that the owl class ComponentProperty is a subclass of rdf:Property, which is not allowed because classes and properties are distinct concepts.

When I load the file with owlready2, this rises the error:

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

This is OWL full. The disjointness of classes and properties is a property of OWL DL.

Ahh, okay. Thanks for your help and the quick reply.

No problem. Likely that you could drop that axiom in a local copy in order to work with owlready2 without that causing any major headaches.
