Dear Andreas, The purpose of these was to ensure that the RDF export of SMW is well-behaved and also valid in OWL. Many tools would find it hard to digest if you would declare a property to be, e.g., a subproperty of rdfs:range.
Unfortunately, rdf and rdfs in particular contain a lot of things that may not all be problematic. However, rdfs:label, for example, should be declared an owl:AnnotationProperty, whereas SMW would declare it as owl:DatatypeProperty. Not sure if this is working as expected either. In general, you can change the blacklist to do whatever you like, but since it seems you plan to use a tool that understands rdf and rdfs vocabulary (why else care?), you should maybe check if it is really working with the RDF output SMW would give you.
