Hi Rupert,
I recently updated the Stanbol install, and I found that the RDF returned by
the EntityHub is missing some props (specifically the dbprop as far as I can
see).
This is the command that I use for testing:
curl -H "accept: application/rdf+xml" "
http://localhost:8080/entityhub/site/dbpedia/entity?id=http://dbpedia.org/resource/Valentino_Rossi
"
which outputs the attached RDF file.
I cleared all of the sling folder (rm -fr sling) and checked the with the
SPAQL end-point at DBpedia, but I wasn't able to fix it.
Does this depend on the mapping.txt file?
Thanks for your help.
BR
David
