Hi Andrew,
it is perfectly fine to have multiple property shapes for the same sh:path
(property). So at the root class you could have
ex:Location
a dash:ShapeClass ;
rdfs:subClassOf owl:Thing ;
sh:property ex:Location-has_part ;
.
ex:Location-has_part
a sh:PropertyShape ;
sh:path ex:has_part ;
sh:name "has part" ;
.
and then define the sh:class in the subclasses
ex:Level
a dash:ShapeClass ;
rdfs:subClassOf ex:Location ;
sh:property ex:Level-has_part ;
.
ex:Level-has_part
a sh:PropertyShape ;
sh:path ex:has_part ;
sh:class ex:Room ;
.
I would move all general constraints into the superclass but anything specific
remains in the subclasses only.
