Oxigraph is a graph database implementing the [SPARQL](https://www.w3.org/TR/sparql11-overview/) standard.
|
|
|
|
Its goal is to provide a compliant, safe, and fast graph database based on the [RocksDB](https://rocksdb.org/) and [Sled](https://sled.rs/) key-value stores.
|
|
It is written in Rust.
|
|
It also provides a set of utility functions for reading, writing, and processing RDF files.
|
|
|
|
Oxigraph is in heavy development and SPARQL query evaluation has not been optimized yet.
|
|
|
|
It is split into multiple parts:
|
|
* [The database written as a Rust library](https://crates.io/crates/oxigraph). Its source code is in the `lib` directory.
|
|
[](https://crates.io/crates/oxigraph)
|
|
[](https://docs.rs/oxigraph)
|
|
* [`pyoxigraph` that exposes Oxigraph to the Python world](https://oxigraph.org/pyoxigraph/). Its source code is in the `python` directory. [](https://pypi.org/project/pyoxigraph/)
|
|
* [JavaScript bindings for Oxigraph](https://www.npmjs.com/package/oxigraph). WebAssembly is used to package Oxigraph into a NodeJS compatible NPM package. Its source code is in the `js` directory.
|
|
[](https://www.npmjs.com/package/oxigraph)
|
|
* [Oxigraph server](https://crates.io/crates/oxigraph_server) that provides a standalone binary of a web server implementing the [SPARQL 1.1 Protocol](https://www.w3.org/TR/sparql11-protocol/) and the [SPARQL 1.1 Graph Store Protocol](https://www.w3.org/TR/sparql11-http-rdf-update/). It uses the [RocksDB](https://rocksdb.org/) key-value store. Its source code is in the `server` directory.

|
[](https://hub.docker.com/repository/docker/oxigraph/oxigraph)
|
|
* [Oxigraph Wikibase](https://crates.io/crates/oxigraph_wikibase), a web server able to synchronize with a [Wikibase instance](https://wikiba.se/). Its source code is in the `wikibase` directory.

Oxigraph implements the following specifications:
|
|
* [SPARQL 1.1 Query](https://www.w3.org/TR/sparql11-query/), [SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/), and [SPARQL 1.1 Federated Query](https://www.w3.org/TR/sparql11-federated-query/).
|
|
* [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/) RDF serialization formats for both data ingestion and retrieval using the [Rio library](https://github.com/oxigraph/rio).
|
|
* [SPARQL Query Results XML Format](http://www.w3.org/TR/rdf-sparql-XMLres/), [SPARQL 1.1 Query Results JSON Format](https://www.w3.org/TR/sparql11-results-json/) and [SPARQL 1.1 Query Results CSV and TSV Formats](https://www.w3.org/TR/sparql11-results-csv-tsv/).
