Hi Dr. Adina, The one I’m using is an empty file. Cause when the war package is deployed, there is no such file named loadrdf under the certain folder. The n-Triples file I’m using is the one listed on the tutorial, the content is :
<http://mynamespace/ProductType1> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://mynamespace/ProductType> . <http://mynamespace/ProductType1> <http://www.w3.org/2000/01/rdf-schema#label> "Thing" . <http://mynamespace/ProductType1> <http://purl.org/dc/elements/1.1/publisher> <http://mynamespace/Publisher1> .
