ETL: Importing RDF file
Requires neo4j plugins: APOC, NEOSEMANTICS.
In order to import RDF file, user also needs uniqueness constraint on Resource label (query in example below) and graph configuration initialized at least with default values (query in example below)
For additional RDF / ontology functions see neosemantics documentations.
Example of RDF import
