Oxigraph is a graph database implementing the SPARQL standard.

Its goal is to provide a compliant, safe, and fast graph database based on the RocksDB key-value store. 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. The development roadmap is using GitHub milestones. Oxigraph internal design is described on the wiki.

It is split into multiple parts:

Oxigraph implements the following specifications:

A preliminary benchmark is provided. There is also a document describing Oxigraph technical architecture.


The easiest way to set up the development environment is to use Visual Studio Code's development containers. Note that this requires Docker Desktop on Windows and Mac and Docker CE/EE on Linux.

Open the repository with Visual Studio Code and use the Command Palette to run Remote-Containers: Rebuild Container. This will re-open the project inside a development container with the Rust toolchain and Python dependencies installed. For more details on how the development container is set up, see .devcontainer/devcontainer.json and .devcontainer/Dockerfile.

For further development details, see the README in each of the respective sub-projects.


Feel free to use GitHub discussions or the Gitter chat to ask questions or talk about Oxigraph. Bug reports are also very welcome.

If you need advanced support or are willing to pay to get some extra features, feel free to reach out to Tpt.
