conforms(node, path: nil, depth: 0, **options) click to toggle source

Specifies the condition that each value node conforms to at least one of the provided shapes. This is comparable to disjunction and the logical “or” operator.

@example

ex:OrConstraintExampleShape
        a sh:NodeShape ;
        sh:targetNode ex:Bob ;
        sh:or (
                [
                        sh:path ex:firstName ;
                        sh:minCount 1 ;
                ]
                [
                        sh:path ex:givenName ;
                        sh:minCount 1 ;
                ]
        ) .
