[Neo] Importing RDF from XML file

Hi Chris,

I'm not an expert on such libraries, but the one I do know of which
has worked for me is OpenRdf parser/importers (RIO)

And I assume you're using the neo-rdf-sail component on top of neo as
your data source, am I right?

F.ex, to set up a Sail with neo4j as backing store:

    final NeoService neo = new EmbeddedNeo( "path/to/neo" );
    final IndexService index = new LuceneIndexService( neo );
    RdfStore rdfStore = new VerboseQuadStore( neo, index );
    Sail sail = new NeoSail( neo, rdfStore );
    Runtime.getRuntime().addShutdownHook( new Thread()
        public void run()
    } );

Then use RIO to import the data:

    Repository repo = new SailRepository( sail );
    RepositoryConnection connection = repo.getConnection();
        new URL( "http://dbpedia.org/data/The_Lord_of_the_Rings" ), "",
        RDFFormat.RDFXML );

I just ran a quick test and it worked fine for me. If you're using
maven you can have these dependencies:

    groupId: org.neo4j
    artifactId: neo-rdf-sail
    version: 0.3-SNAPSHOT

    groupId: org.openrdf.sesame
    artifactId: sesame-rio-rdfxml
    version: 2.1.1

    groupId: org.openrdf.sesame
    artifactId: sesame-repository-sail
    version: 2.1.1

Hopefully it will work fine for you too! Don't hesitate to come back
with more questions.
