RDFLib
RDFLib is a pure Python package for working with RDF. RDFLib contains most things you need to work with RDF, including:
- parsers and serializers for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, Trig, JSON-LD and even HexTuples
- a Graph interface which can be backed by any one of a number of Store implementations
- Store implementations for in-memory, persistent on disk (Berkeley DB) and remote SPARQL endpoints
- additional Stores can be supplied via plugins
- a SPARQL 1.1 implementation - supporting SPARQL 1.1 Queries and Update statements
- SPARQL function extension mechanisms
RDFlib Family of packages
The RDFlib community maintains many RDF-related Python code repositories with different purposes. For example:
- rdflib - the RDFLib core
- sparqlwrapper - a simple Python wrapper around a SPARQL service to remotely execute your queries
- pyLODE - An OWL ontology documentation tool using Python and templating, based on LODE.
- pyrdfa3 - RDFa 1.1 distiller/parser library: can extract RDFa 1.1/1.0 from (X)HTML, SVG, or XML in general.
- pymicrodata - A module to extract RDF from an HTML5 page annotated with microdata.
- pySHACL - A pure Python module which allows for the validation of RDF graphs against SHACL graphs.
- OWL-RL - A simple implementation of the OWL2 RL Profile which expands the graph with all possible triples that OWL RL defines.

Help with maintenance of all of the RDFLib family of packages is always welcome and appreciated.
