Hi, as part of my master thesis I developed a new SPARQL plugin for Neo4j. The RDF model differs essentially and significantly from the property graph, based on the fact that the relationships / predicates cannot be. In neo4j, it's 1 relationship amongst two nodes, with each node having a property. Graph databases that use a property-graph model such as neo4j have a certain level of popularity.

For those using classic RDF/SPARQL, you can use the convention that edges with properties in Neo4j can be represented as entities in RDF. These are in many ways comparable to RDF databases (triplestores), but I will highlight three differences: The underlying datamodel in most graph databases is a Property Graph (PG). In Neo4j, a node in the graph corresponds to an entity in a domain. Due to its graph data model, Neo4j is highly agile and blazing fast. RDF is a W3C standard model for data interchange. Customers are excited to see support for AWS IAM, Amazon Neptune RDF, and Neo4j 3. RDF/OWL and Neo4j.

RDF Triple Stores To summarize, both graph databases and triple stores are designed to store linked data. An RDF graph can be seen as a set of triples, roughly analogous to nodes and edges in a graph database. In addition, developers can create applications with the ability to edit Amazon Neptune, JanusGraph, Microsoft Azure Cosmos, OrientDB, and Apache TinkerPop—as well as Neo4j graph databases. You can use a triple store or graph NoSQL database if you have a web of interconnected data, or you can simply tag your data and infer relationships according to the records that share the same tags.
