Pyoxigraph is a Python graph database library implementing the `SPARQL <https://www.w3.org/TR/sparql11-overview/> `_ standard.
It is built on top of `Oxigraph <https://github.com/oxigraph/oxigraph> `_ using `PyO3 <https://pyo3.rs/> `_ .
It offers two stores with `SPARQL 1.1 Query <https://www.w3.org/TR/sparql11-query/> `_ 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 <https://www.w3.org/TR/turtle/> `_ ,
`TriG <https://www.w3.org/TR/trig/> `_ ,
`N-Triples <https://www.w3.org/TR/n-triples/> `_ ,
`N-Quads <https://www.w3.org/TR/n-quads/> `_ and
`RDF/XML <https://www.w3.org/TR/rdf-syntax-grammar/> `_ .
Pyoxigraph is `distributed on Pypi <https://pypi.org/project/pyoxigraph/> `_ .
There exists also a small library providing `rdflib <https://rdflib.readthedocs.io> `_ stores using pyoxigraph: `oxrdflib <https://github.com/oxigraph/oxrdflib> `_ .
Oxigraph and pyoxigraph source code are on `GitHub <https://github.com/oxigraph/oxigraph/tree/master/python> `_ .
