In their own words
Oxigraph
Oxigraph is a free graph database and RDF/SPARQL toolkit available for Linux, web, API, and self-hosted use. It implements SPARQL 1.1 Query, Update, and Federated Query, and handles RDF formats including Turtle, TriG, N-Triples, N-Quads, RDF/XML, JSON-LD, and N3. The project provides a Rust library, standalone Rust crates, Python bindings, JavaScript bindings, and a command-line tool. That CLI can start an HTTP server implementing the SPARQL 1.1 Protocol and Graph Store Protocol. By default, the server listens on localhost:7878 and offers a YASGUI-based HTML interface for running SPARQL requests. REST endpoints support queries, updates, and RDF dataset access. Installation options include Cargo, Docker, PyPI, conda-forge, and prebuilt binaries. Pyoxigraph supplies in-memory and disk-based stores, and oxrdflib connects rdflib stores to Pyoxigraph. Storage is based on RocksDB, and licensing is Apache 2.0 or MIT.
