[dxwg] rdf:property and owl:datatypeProperty, problem with poolParty import

smrgeoinfo has just created a new issue for https://github.com/w3c/dxwg:

== rdf:property and owl:datatypeProperty, problem with poolParty import ==
I'm trying to import dcat.ttl into a poolParty project, and errors are getting thrown along the lines of 
Invalid data! http://www.w3.org/ns/dcat#byteSize was defined as 
http://www.w3.org/2002/07/owl#DatatypeProperty and 
http://www.w3.org/2002/07/owl#ObjectProperty. Those classes are disjoint and cannot be used 
on the same resource.
It appears that this is because the property is declared 
  rdf:type rdf:Property ;
  rdf:type owl:DatatypeProperty ;
and according to [owl ref](https://www.w3.org/TR/owl-ref/) Both owl:ObjectProperty and owl:DatatypeProperty are subclasses of the RDF class rdf:Property. it looks like the rdf:Property declaration is leading to interpretation that the property is both and ObjectProperty and DatatypeProperty.   

Should the type declaration be only 'rdf:type owl:DatatypeProperty ;'?
