shapes-ISSUE-66 (ill-founded): SHACL should not be ill-founded [SHACL Spec]
http://www.w3.org/2014/data-shapes/track/issues/66
Raised by: Peter Patel-Schneider
On product: SHACL Spec
The current SHACL working draft is ill-founded, in that there are shapes and graphs where the determining the shape violations cannot be correctly done.
One example is the graph
ex:i rdf:type ex:C .
ex:i ex:p ex:i .
and the shape
exs:S rdf:type sh:Shape;
sh:classScope ex:C ;
sh:property [ sh:predicate ex:p ;
sh:minCount 1 ; sh:maxCount 1 ;
sh:valueShape exs:S ] .
where there is no way to determine whether ex:i has a shape violation.
