RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information.

The library contains parsers and serializers for RDF/XML, N3, NTriples, Turtle, TriX, RDFa and Microdata.

The library presents a Graph interface which can be backed by any one of a number of store implementations including: memory and Sleepycat/BerkeleyDB. With extension projects, stores based on MySQL, SQLite, remote SPARQL Endpoints, etc. are also possible.
