AI-native ontology engine: a Rust MCP server with tools for building, validating, querying, and reasoning over RDF/OWL ontologies. In-memory Oxigraph triple store, native OWL2-DL tableaux reasoner, SHACL validation, SPARQL, versioning. Single binary, no JVM.

💫 Deploy SPARQL endpoints from RDFLib Graphs to serve RDF files, machine learning models, or any other logic implemented in Python

An attempt to run oxigraph on the Internet Computer

This server loads multiple Zotero libraries into an RDF graph, exposes a local SPARQL endpoint, and allows exporting the graph.

Oxigraph RDF Store as a serverless SPARQL endpoint for Deno Deploy

Multi Backend Knowledge Graph Environment

SPARQL endpoint to represent pangenomic data

A high-performance, full-featured web API for Oxigraph

A Solid personal data server in Rust. Every resource is a named graph in one embedded quad store, so the whole pod is one queryable dataset.

A native Rust SHACL 1.2 validator — Core (§7) + SHACL-SPARQL, over oxigraph or an in-memory graph

A Next.js web interface for exploring and managing RDF triplestores. Supports QLever, Virtuoso, and Oxigraph.

A SPARQL playground directly usable from the web

Read-only SPARQL 1.1 endpoint + dereferenceable IRIs over the oxigraph ethical-decision lattice

Portable SPARQL 1.1 + SHACL Core engine compiled to WebAssembly, for querying and validating RDF tx-graphs in the browser, on the server, and in CI.
