Instance Method Details

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

Specifies the condition that each value node conforms to all provided shapes. This is comparable to conjunction and the logical “and” operator.

Examples:

ex:SuperShape
	a sh:NodeShape ;
	sh:property [
		sh:path ex:property ;
		sh:minCount 1 ;
	] .

ex:ExampleAndShape
	a sh:NodeShape ;
	sh:targetNode ex:ValidInstance, ex:InvalidInstance ;
	sh:and (
		ex:SuperShape
		[
			sh:path ex:property ;
			sh:maxCount 1 ;
		]
	) .

Parameters:

  • node (RDF::Term) —

    focus node

  • path (RDF::URI, SPARQL::Algebra::Expression) (defaults to: nil) —

    (nil) the property path from the focus node to the value nodes.

  • options (Hash{Symbol => Object})

Returns:
