What is the right configuration to connect a RDF/SPARQL client like Protégé (protege.stanford.edu) or Gephi (http://gephi.github.io/, Semantic Web Import Plugin) with the tripplestore "4store"? (http://4store.org/trac/wiki/SparqlServer)?
Error in the log of Semantic Web Import Plugin: fr.inria.edelweiss.sparql.RdfParser$1 fatalError SCHWERWIEGEND: Premature end of file.
I am not familiar with 4Store but it has a sparql endpoint http://localhost:8000/sparql/ which can be used both by Protege/Gephi
