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://crates.io/crates/oxigraph>`_ using `PyO3 <https://pyo3.rs/>`_.
It also provides a set of utility functions for reading, writing, and processing RDF files in
`JSON-LD 1.0 <https://www.w3.org/TR/json-ld/>`_,
`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/>`_ and `on conda-forge <https://anaconda.org/conda-forge/pyoxigraph>`_.
There is also a small library providing a `rdflib <https://rdflib.readthedocs.io>`_ store using pyoxigraph: `oxrdflib <https://github.com/oxigraph/oxrdflib>`_.
Oxigraph and pyoxigraph source code are on `GitHub <https://github.com/oxigraph/oxigraph/tree/main/python>`_.
Installation
""""""""""""
Pyoxigraph is distributed on `Pypi <https://pypi.org/project/pyoxigraph/>`_.

from pyoxigraph import *
store = Store()
ex = NamedNode('http://example/')
schema_name = NamedNode('http://schema.org/name')
store.add(Quad(ex, schema_name, Literal('example')))
for binding in store.query('SELECT ?name WHERE { <http://example/> <http://schema.org/name> ?name }'):
print(binding['name'].value)
