fukurow (headless wasm)

Headless WebAssembly bindings for the Fukurow reasoning engine. Pure-compute APIs for OWL reasoning, SHACL validation, and SPARQL querying. Works on Vercel Edge, Web Workers, and modern browsers.

Install

pnpm add fukurow

Usage (Node/Vercel Serverless)

import init, { reason_owl, validate_shacl, query_sparql } from 'fukurow';

await init();

const out = reason_owl(JSON.stringify(inputJsonLd), JSON.stringify({ engine: 'lite' }));
const report = validate_shacl(JSON.stringify(data), JSON.stringify(shape));
const results = query_sparql(JSON.stringify(data), 'SELECT * WHERE { ?s ?p ?o }');

Implementation Status

🎉 Full Fukurow WebAssembly implementation!

• reason_owl: ✅ Implemented - Uses fukurow-lite OWL Lite reasoner for class hierarchy inference
• validate_shacl: ✅ Implemented - Full SHACL Core validation with detailed violation reports
• query_sparql: ✅ Implemented - SPARQL 1.1 SELECT, ASK, CONSTRUCT, and DESCRIBE queries

All functions use actual implementations from the fukurow ecosystem, performing real reasoning, validation, and querying operations.

Notes

• This package is headless: it performs no I/O and has no DOM/Node dependencies.
• Designed for Vercel serverless functions (both Node and Edge runtimes).
• If your CSP forbids unsafe-eval, wasm-bindgen glue may require adjustments.
