Sorry didnt get back to this.. the shape declaration looks like:
ex:MyClass-pshape a sh:PropertyShape ; sh:path <http://topbraid.org/corpus#topic> ; sh:class skos:Concept ; sh:description "Concept used to tag objects in this document" ; sh:nodeKind sh:IRI ; . the other thing that happens is that if you add topic to the search results display as an extra column it is blank - and inspection of the network traffic shows the underlying graphql query is returning topic:[] incorrectly for everything.
