I retract the rdfs:subPropertyOf rdfs:label/skos:prefLabel suggestion.
It doesn't align:


I agree your "shortcut property" rationalization makes more sense as a
justification for an owl:DatatypeProperty. I think it's an important use
case because there are many times where someone knows the name of
something but can't coin a de-referenceable URI.

foaf:name and skos:pref/altLabels are all rdfs:subClassOf rdfs:label, so
sure. Presumably this is the common denominator that would correspond to
the creatorLabel datatype property.

It worries me that foaf:focus doesn't have an owl:inverseOf to point in
that direction. This will make inferencing harder in mixed datasets
where some sources reference a modeled thing and others reference a
corresponding concept.
