Question on sh:values

[Felix Sasaki]

I am trying the sh:values feature

https://www.topquadrant.com/graphql/values.html

with the shacl api

https://github.com/TopQuadrant/shacl

using the example attached. 

Doing an inference, I get the triples generated as expected:

<http://example.com/instancedata/JohnKennedy> <http://schema.org/children>  <http://example.com/instancedata/CarolineKennedy> , <http://example.com/instancedata/PatrickBKennedy> , <http://example.com/instancedata/JohnKennedyJr> . 

Trying validation, I get an error message for JohnKennedy:

 sh:result    [ a                             sh:ValidationResult ;

                 sh:focusNode                  kennedys:JohnKennedy ;

                 sh:resultMessage              "Property needs to have at least 3 values, but found 0" ;

                 sh:resultPath                 schema:children ;

                 sh:resultSeverity             sh:Violation ;

                 sh:sourceConstraintComponent  sh:MinCountConstraintComponent ;

                 sh:sourceShape                _:b0               ] ;

I would have expected that the validation takes the triples into account that have been generated via sh:values. Is this wrong, or is there an issue with my SHACL example?

By default, SHACL will not apply any inferences before validation. If you first want to run the (sh:values) rules, try setting the sh:entailment property

    https://www.w3.org/TR/shacl/#shacl-rdfs

at some subject (typically the owl:Ontology instance of your graph) with the value sh:Rules

    https://w3c.github.io/shacl/shacl-af/#Rules

Thanks a lot, Holger, that worked.
