Instance Method Details

#conforms(node, path: nil, depth: 0, **options) ⇒ Array<SHACL::ValidationResult>

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.

Examples:

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 ;
    ]
  ) .

Parameters:

  • node (RDF::Term)
  • options (Hash{Symbol => Object})

Returns:
