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.
