The target is about resources that are targeted - in this case all ?s in ?s ex:someproperty ?o. If you put constraints directly on a Node Shape, you are constraining values of the targeted resources. If you put constraints into a property shape, you are constraining values that can be reached from the targeted resources via the specified path. You could do ex:someNodeShape1 a sh:NodeShape ; sh:targetSubjectsOf ex:someproperty ; sh:class ex:somedomainclass . > > Which is not what you want to say. > > You would need to either use an inverse path on ex:someproperty - see > https://www.w3.org/TR/shacl/#property-path-inverse > <https://www.w3.org/TR/shacl/#property-path-inverse> or, alternatively, use > sh:class ex:somerangeclass. > > If you make these changes to your property shapes, you will get the > validation to ensure the "right values" for the subjects and objects of > triples.
