A Tale of Two Graphs: Property Graphs and RDF - Andy Seaborne and Paolo Castagna, Cloudera

Sign up or log in to save this to your schedule and see who's attending!

Property Graphs and the Resource Description Framework (RDF) are both graph data models. Property Graphs originated with data practitioners while RDF was developed at W3C as an information model for the web. Both graph data models are "schema-neutral", there is no rigid organization of data up-front. Applications decide which part of the data graph to use and how to view it. New data and new applications can be introduced at any time without disturbing existing usage.

In this talk we will introduce both data models and look at some uses to show where they are (and are not) used. We will look at contrasting features of the data models by looking at use cases.

We will then look at two systems, Apache Spark/GraphX, for property graphs, and Apache Jena, for RDF databases, and how they deal with graph structure and how they can scale to big data.
