shapes-ISSUE-206 (Target node): Not clear how a node target specifies targets for a shape [SHACL Spec]
http://www.w3.org/2014/data-shapes/track/issues/206
Raised by: Karen Coyle
On product: SHACL Spec
>From Peter's email: https://lists.w3.org/Archives/Public/public-rdf-shapes/2016Nov/0000.html
"A node target is defined with the sh:targetNode predicate. Each value of
sh:targetNode can be an IRI or a literal. Each value of a node target
defines a node to validate in the data graph." This doesn't say how a node
target specifies targets for a shape.
"The following SPARQL query specifies the semantics of node targets. The
variable targetNode is assumed to be pre-bound to the given value of
sh:targetNode." This also doesn't say how a node target specifies targets
for a shape.
"SPARQL DEFINITION
SELECT DISTINCT ?this # ?this is the focus node
WHERE {
BIND ($targetNode AS ?this) # $targetnote is pre-bound to ex:Alice
}" This also doesn't say how a node target specifies targets for a shape.
