Neosemantics is a plugin that enables the use of RDF in Neo4j. RDF is a W3C standard model for data interchange. This effectively means that Neosemantics makes it possible to
Store RDF data in Neo4j in a lossless manner (imported RDF can subsequently be exported without losing a single triple in the process).
On-demand export property graph data from Neo4j as RDF.
Other features in Neosemantics include model mapping and inferencing on Neo4j graphs.
