Hello
Please install neosemantics plugin for your current installation. If it is already there then you have misplaced CSV data file somewhere on your local system.
Thanks

Hi Sudhir,
I have installed it already.

hi there.
to proper import rdf i suggest the following:

1. empty graph db.
2. preform create constraint n10s_unique_uri IF NOT EXISTS on (r:Resource) ASSERT r.uri IS UNIQUE
3. preform n10s.graphconfig.init command.
4. (optional) preform n10s.nsprefixes.addFromText.
5. n10s.rdf.import.fetch()

In my project i use the above commands in the following manner:

CREATE CONSTRAINT n10s_unique_uri IF NOT EXISTS  ON (r:Resource) ASSERT r.uri IS UNIQUE;
CALL n10s.graphconfig.init({
            handleVocabUris: 'IGNORE',
            handleMultival: 'ARRAY',
            subPropertyOfRel: "is_a_subproperty",
            subClassOfRel: "is_a",
            handleRDFTypes: 'LABELS_AND_NODES'
});
CALL n10s.nsprefixes.addFromText('<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
                 xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
                 xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
                 xmlns:owl="http://www.w3.org/2002/07/owl#"
                 xml:base="ontology.owl"
                 xmlns="ontology.owl#">');
CALL n10s.rdf.import.fetch("file:///c://Users/laviben/PycharmProjects/overwatch/data/input/DataBaseData/Ontology.owl", "RDF/XML");

another important tip:
make sure your neo4j version is compatible with the neosemantics package.
that can be verified on the release area in the following link:
