@origintrail-official/dkg-storage

Triple store abstraction layer for DKG V9. 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';

const store = createTripleStore({ backend: 'oxigraph', path: './data' });
const graphs = new GraphManager(store);

await store.insert(quads, { graph: 'urn:paranet:example:data' });
const result = await store.query('SELECT * WHERE { ?s ?p ?o } LIMIT 10');
