What is NSMNTX? NSMNTX is a plugin that enables the use of RDF in Neo4j ● Store RDF data in Neo4j in a lossless manner ● On-demand export property graph data from Neo4j as RDF ● model mapping ● Inferencing

Importing RDF into Neo4j

Model Mapping

Model Mapping semantics.mapping.addSchema(... semantics.mapping.addMappingToSchema(... call semantics.mapping.listMappings(... semantics.mapping.dropMapping(... semantics.mapping.addCommonSchemas(... semantics.mapping.dropSchema(...

Ontology Management Publish my onto /rdf/onto Import an onto semantics.importOntology( semantics.importRDF(...

Inferencing

Inferencing Derive graph elements from explicit definitions (ontologies) (P)semantics.inference.nodesLabelled(... (P)semantics.inference.nodesInCategory(... (F)semantics.inference.hasLabel(... (F)semantics.inference.inCategory(... (P)semantics.inference.getRels(...

And now… the Hunger games :)

Both RDF and A. sets of records? the Property B. documents? Graph model represent the C. a graph? world as...

A. Import RDF data and store it into Neo4j NSMNTX will let you... B. Export your Neo4j graph as RDF C. all of the above

Which NSMNTX A. semantics.importOntology procedure B. semantics.importRDF would I use if I wanted to C. both would import the ontology, but import an OWL semantics.importOntology builds a simplified and more ontology into user friendly representation of the ontology in Neo4j Neo4j?

Thank you!
