[SPARQL](https://www.w3.org/TR/sparql11-overview/) standard.\n\nIts goal is to provide a compliant, safe, and fast graph database based on the [RocksDB](https://rocksdb.org/) key-value store.\nIt is written in Rust.\nIt also provides a set of utility functions for reading, writing, and processing RDF files.\n\nOxigraph is in heavy development and SPARQL query evaluation has not been optimized yet.\nThe development roadmap is using [GitHub milestones](https://github.com/oxigraph/oxigraph/milestones?direction=desc\u0026sort=completeness\u0026state=open).\nOxigraph internal design [is described on the wiki](https://github.com/oxigraph/oxigraph/wiki/Architecture).\n\nOxigraph implements the following specifications:\n\n- [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/).\n- [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.\n- [SPARQL Query Results XML Format](https://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/).\n\nIt is split into multiple parts:\n\n- [The database written as a Rust library](./lib/oxigraph). Its source code is in the `lib` directory.\n  [![Latest Version](https://img.shields.io/crates/v/oxigraph.svg)](https://crates.io/crates/oxigraph)\n  [![Released API docs](https://docs.rs/oxigraph/badge.svg)](https://docs.rs/oxigraph)\n- [`pyoxigraph` that exposes Oxigraph to the Python world](./python). Its source code is in the `python` directory. [![PyPI](https://img.shields.io/pypi/v/pyoxigraph)](https://pypi.org/project/pyoxigraph/)\n- [JavaScript bindings for Oxigraph](./js). WebAssembly is used to package Oxigraph into a NodeJS compatible NPM package. Its source code is in the `js` directory.\n  [![npm](https://img.shields.io/npm/v/oxigraph)](https://www.npmjs.com/package/oxigraph)\n- [Oxigraph binary](./cli) that provides a standalone command-line tool allowing to manipulate RDF data and spawn 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/). Its source code and instructions (including Docker) are in the `cli` directory.\n  Note that it was previously named [Oxigraph server](https://crates.io/crates/oxigraph-server).\n  [![Latest Version](https://img.shields.io/crates/v/oxigraph-cli.svg)](https://crates.io/crates/oxigraph-cli)\n\nAlso, some parts of Oxigraph are available as standalone Rust crates:\n* [`oxrdf`](./lib/oxrdf), datastructures encoding RDF basic concepts (the [`oxigraph::model`](crate::model) module).\n* [`oxrdfio`](./lib/oxrdfio), a unified parser and serializer API for RDF formats (the [`oxigraph::io`](crate::io) module). It itself relies on:\n  * [`oxttl`](./lib/oxttl), N-Triple, N-Quad, Turtle, TriG and N3 parsing and serialization.\n  * [`oxrdfxml`](./lib/oxrdfxml), RDF/XML parsing and serialization.\n* [`spareval`](./lib/spareval), a SPARQL evaluator.\n* [`spargebra`](./lib/spargebra), a SPARQL parser.\n* [`sparesults`](./lib/sparesults), parsers and serializers for SPARQL result formats.\n* [`sparopt`](./lib/sparopt), a SPARQL optimizer.\n* [`oxsdatatypes`](./lib/oxsdatatypes), an implementation of some XML Schema datatypes.\n\nThe library layers in Oxigraph. The elements above depend on the elements below:\n![Oxigraph libraries architecture diagram](./docs/arch-diagram.svg)\n\nA preliminary benchmark [is provided](bench/README.md). There is also [a document describing Oxigraph technical architecture](https://github.com/oxigraph/oxigraph/wiki/Architecture).\n\nWhen cloning this codebase, don't forget to clone the submodules using\n`git clone --recursive https://github.com/oxigraph/oxigraph.git` to clone the repository including submodules or\n`git submodule update --init` to add the submodules to the already cloned repository.\n\n\n## Help\n\nFeel free to use [GitHub discussions](https://github.com/oxigraph/oxigraph/discussions) or [the Gitter chat](https://gitter.im/oxigraph/community) to ask questions or talk about Oxigraph.\n[Bug reports](https://github.com/oxigraph/oxigraph/issues) are also very welcome.\n\nIf you need advanced support or are willing to pay to get some extra features, feel free to reach out to [Tpt](https://github.com/Tpt/).\n\n\n## License\n\nThis project is licensed under either of\n\n- Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or\n  http://www.apache.org/licenses/LICENSE-2.0)\n- MIT license ([LICENSE-MIT](LICENSE-MIT) or\n  http://opensource.org/licenses/MIT)\n\nat your option.\n\n### Contribution\n\nUnless you explicitly state otherwise, any contribution intentionally submitted for inclusion in Oxigraph by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.\n\n\n## Sponsors\n\n* [Zazuko](https://zazuko.com/), a knowledge graph consulting company.\n* [RelationLabs](https://relationlabs.ai/) that is building [Relation-Graph](https://github.com/relationlabs/Relation-Graph), a SPARQL database module for the [Substrate blockchain platform](https://substrate.io/) based on Oxigraph.\n* [Field 33](https://field33.com) that was building [an ontology management platform](https://plow.pm/).\n* [Magnus Bakken](https://github.com/magbak) who is building [Data Treehouse](https://www.data-treehouse.com/), a time-series + RDF datalake platform, and [chrontext](https://github.com/magbak/chrontext), a SPARQL query endpoint on top of joint RDF and time series databases.\n* [DeciSym.AI](https://www.decisym.ai/) a cyber security consulting company providing RDF-based software.\n* [ACE IoT Solutions](https://aceiotsolutions.com/), a building IOT platform.\n* [Albin Larsson](https://byabbe.se/) who is building [GovDirectory](https://www.govdirectory.org/), a directory of public agencies based on Wikidata.\n\nAnd [others](https://github.com/sponsors/Tpt).
