Hi David I see the need for often context (domain)-sepcific constraints.
But my question is about universal constraints like an rdfs:range or a property being functional etc. In https://spinrdf.org/shacl-and-owl.html there is the example for functional. I used this approach for the range: ex:accuracy a rdf:Property ; . ex:accuracyShape a sh:PropertyShape ; sh:targetSubjectsOf ex:accuracy ; sh:path ex:accuracy ; sh:class smls:QuantityValue ; . There are now 2 issues. Issue 1: - is the red needed or not? Issue 2: - even if there is a domain so this constraint can be modelled in the context of a nodeshape, wouldn’t it be better to do it as above (since domain and range are completely independent, so the range constraint also holds for instances of the property not of type domain) Dr. ir.

But if I have a domain AND a range, I can do the range via sh:property/sh:class/sh:datatype in the NodeShape (as we did now). My issue is: the range restriction does not only hold in the domain case: it always holds..its independent of that domain. I’m not sure why this is an issue. A named PS can use sh:class or sh:datatype to specify the required “range" with no mention of “domain”. I’m not sure I agree - see below. So...shouldnt a range always be modelled separately from the domain nodeshape, in general as a property shape. Not necessarily. Some PropertyShapes (i.e. properties) only make sense in the context of a specific NodeShape (i.e. Class). The US has Social Security Number with a required NNN-NN-NNNN pattern and only instances of class USPerson (i.e. U.S. citizens, permanent residents, and temporary (working) residents) can have that - class Dog cannot, so not necessary to model it outside the context of Person. In fact, you might argue that making it a separate named PS with just a sh:path and sh:datatype creates the potential for misuse by other modellers using your shapes, and therefore choose not to do so. (subissue being then whether sh:allSubjectsOf is needed or not, see reply Jan; I am still unsure there: you have to give a path and that path should start at some target or is there some kind of default in play here?) In your simple case, all that's required in SHACL is that PS sh:path should be the IRI of the predicate (plus the sh:class or sh:datatype). You can then say more in the NodeShapes that control where the PS is used. Cheers, David Dr. ir. H.M.

Technically, x:Vehicle-loadLevel is independent which may not be exactly what you want. Since you had a domain on the property, you’ve said it is not independent of subject - so I used the PS name to make the intent clear. I personally prefer the sh:property style of modelling because I can look at the NodeShape and it’s superclasses to find every property shape that comes into play. That does mean when focusing on the PS I have to do a search to “Find references” for the NS (but by using the PS naming convention of Class-Property I don’t actually need to do that to know where the PS is used).

The shape is a property shape. Wherever the property in the property path occurs (i.e. ex:loadLevel), the constraint will be checked/validated.

Not sure about “best” but I did this and it works great and aligns with your model: 1) Added to ensure drop-down lists show the right instances for selection in a UI ex:Heavy a ex:LoadLevelType ; rdfs:label "Heavy" ; . ex:Light a ex:LoadLevelType ; rdfs:label "Light" ; . ex:Normal a ex:LoadLevelType ; rdfs:label "Normal" ; . 2) sh:in in the PropertyShape gives me a violation if I go in and make an instance with anything other than the 3 selections ex:Vehicle-loadLevel a sh:PropertyShape ; sh:path ex:loadLevel ; sh:class ex:LoadLevelType ; sh:in ( ex:Light ex:Normal ex:Heavy ) ; .
