Pyoxigraph (Oxigraph for Python)

Pyoxigraph is a graph database library implementing the SPARQL standard. It is a Python library written on top of Oxigraph.

Pyoxigraph offers two stores with SPARQL 1.1 capabilities. One of the store is in-memory, and the other one is disk based.

It also provides a set of utility functions for reading, writing and processing RDF files in Turtle, TriG, N-Triples, N-Quads and RDF/XML.

Pyoxigraph is distributed on Pypi. Run pip install pyoxigraph to install it.

There exists also a small library providing rdflib stores using pyoxigraph: oxrdflib.

Pyoxigraph documentation is available on the Oxigraph website.

Build the development version

To build and install the development version of pyoxigraph you need to clone this git repository and to run pip install . in the python directory (the one this README is in).

Help

Feel free to use GitHub discussions or the Gitter chat to ask questions or talk about Oxigraph. Bug reports are also very welcome.

If you need advanced support or are willing to pay to get some extra features, feel free to reach out to Tpt.

How to contribute

Pyoxigraph is written in Rust using PyO3.

Pyoxigraph is built using Maturin. Maturin could be installed using the pip install 'maturin>=0.9,<0.10'. To install a development version of Oxigraph just run maturin develop in this README directory.

Tests

The Python bindings tests are written in Python. To run them use python -m unittest in the tests directory.

Docs

The Sphinx documentation can be generated and viewed in the browser using the following command:

sphinx-autobuild docs docs/_build/html

Note that you will need to have sphinx-autobuild installed. This should be installed already if you are using this repository's development container.

Alternatively, you can use sphinx-build with Python's http.server to achieve the same thing.

Python type hints

Python type hints for pyoxigraph are defined in the python stub file pyoxigraph.pyi. This is the final python stub file generated from base.pyi using generate_type_hints.py. pyoxigraph.pyi should not be modified directly. Instead, modify base.pyi and run the following command in this directory:

python generate_type_hints.py
