Oxigraph
Oxigraph is a small, embeddable RDF triple store and SPARQL 1.1 engine written in Rust. It supports RDF/XML, Turtle, N-Triples, N-Quads, and TriG formats, and is designed for Semantic Web and knowledge graph applications where a lightweight, embeddable solution is preferred over a full server deployment.
