@origintrail-official/dkg-storage

Triple store abstraction layer for DKG V10. Provides a unified API over multiple RDF storage backends with named graph management and private content storage.

Features

• Backend adapters — pluggable triple store implementations:
  • OxigraphStore — embedded WASM/native store, no external dependencies
  • OxigraphWorkerStore — worker-thread variant for non-blocking operations
  • BlazegraphStore — connects to a running Blazegraph SPARQL endpoint
  • SparqlHttpStore — generic adapter for any SPARQL 1.1 compliant endpoint
• Graph manager — named graph lifecycle (create, drop, list) with paranet-scoped data and metadata graphs
• Private content store — encrypted triple storage for private KA triples, separate from the public graph
• Custom adapters — registerTripleStoreAdapter() to plug in any storage backend

Usage

import { createTripleStore, GraphManager } from '@origintrail-official/dkg-storage';

// In-memory store
const memStore = await createTripleStore({ backend: 'oxigraph' });

// Persistent store (requires a path)
const store = await createTripleStore({
  backend: 'oxigraph-persistent',
  options: { path: './data' },
});

const graphs = new GraphManager(store);

await store.insert(quads);
const result = await store.query('SELECT * WHERE { ?s ?p ?o } LIMIT 10');
