shapes-ISSUE-171 (negated sh:classIn): sh:classIn SPARQL definition incorrect [SHACL Spec]
http://www.w3.org/2014/data-shapes/track/issues/171
Raised by: Peter Patel-Schneider
On product: SHACL Spec
The SPARQL definition of sh:classIn below is incorrrect, as it returns value nodes for which none of the classes are not a SHACL type for it instead of none of the classes are a SHACL type for it.
SELECT $this ($this AS ?subject) $predicate (?value AS ?object)
WHERE {
$this $predicate ?value .
FILTER NOT EXISTS {
GRAPH $shapesGraph {
$classIn (rdf:rest*)/rdf:first ?class .
}
FILTER NOT EXISTS { ?value rdf:type/rdfs:subClassOf* ?class }
}
}
