What Oxigraph is

Oxigraph is a graph database and toolkit for working with RDF data and SPARQL. It implements SPARQL 1.1 Query, Update, and Federated Query, and supports formats such as Turtle, TriG, N-Triples, N-Quads, RDF/XML, and JSON-LD for data ingestion and retrieval. The project includes a Rust library, Python and JavaScript bindings, and a command-line tool that can launch an HTTP server.

The server provides an HTML interface based on YASGUI for running SPARQL requests, along with REST endpoints for queries, updates, and RDF dataset access. The CLI is available through Cargo, Docker, PyPI, conda-forge, or prebuilt binaries. Pyoxigraph provides in-memory and disk-based stores. The project is free and dual-licensed under Apache License 2.0 or MIT, at the user's choice. One stated limitation is that SPARQL query evaluation has not yet been optimized.

Who it suits

Oxigraph suits developers who need RDF storage and SPARQL tools, including those building Rust projects or using Python and JavaScript bindings. It can also suit users who want to run a local HTTP server or access RDF data through REST endpoints.

Getting started

Visit the Oxigraph project on GitHub: https://github.com/oxigraph/oxigraph.
Install the command-line tool through Cargo, Docker, PyPI, conda-forge or a prebuilt binary.
Start the command-line tool's HTTP server; it listens on localhost:7878 by default.
Run SPARQL requests through the YASGUI-based HTML interface or use the server's REST endpoints.
For Python use, install Pyoxigraph through PyPI or conda-forge.

Verdict

Oxigraph combines RDF storage, SPARQL support, language bindings, and a command-line server in a free toolkit. Its stated query-evaluation limitation is a key consideration for workloads that depend on query performance.
