I think the Distribution
shape in distribution.ttl is broken.
Both the SHACL Playground and SHACL-JS throw the error Cannot find validator for constraint component http://www.w3.org/ns/shacl#MinCountConstraintComponent
.
The error seems to be in the first property shape. According to SHACL-SHACL a sh:PropertyShape
needs to have exactly one sh:path
predicate. However, the first property shape of Distribution
does not have a sh:path
predicate, instead it defines two optional paths using an sh:or
-construct with other property shapes.
A possible solution would be to define an alternative path using sh:path [ sh:alternativePath (dcat:accessURL dcat:downloadURL) ] ;
. However, then there could be only one sh:name
and sh:description
.
Another solution would be to not use sh:and
in the node shape and instead link via sh:property
to each property shape. Then there could also be an sh:or
for the property shapes of dcat:accessURL
and dcat:downloadURL
.
