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
|
|
`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>`_.
