rdflib 3.2.0rc

Introduction

A pure Python package providing the core RDF constructs.

The rdflib package is intended to provide core RDF types and interfaces for working with RDF. The package defines a plugin interface for parsers, stores, and serializers that other packages can use to implement parsers, stores, and serializers that will plug into the rdflib package.

graph

An RDF graph is a set of RDF triples. The set of nodes of an RDF graph is the set of subjects and objects of triples in the graph.

named graph

Named Graphs is the idea that having multiple RDF graphs in a single document/repository and naming them with URIs provides useful additional functionality. – http://www.w3.org/2004/03/trix/
