public class RDFProcedures
extends CommonProcedures

Created by jbarrasa on 21/03/2016.

RDF importer based on: 1. Instancdes of DatatypeProperties become node attributes 2. rdf:type relationships are transformed either into labels or relationships to nodes representing the class 3. Instances of ObjectProperties become relationships ( See https://jbarrasa.com/2016/06/07/importing-rdf-data-into-neo4j/ )
