This package allows you to setup LDP direct containers in which LDP resources can be manipulated.


  • Handles triples, turtle and JSON-LD format
  • Automatic creation of containers on server start
  • Full container management: create, attach resources, detach, clear, delete...




$ npm install @semapps/ldp --save


const { LdpService } = require('@semapps/ldp');
module.exports = {
mixins: [LdpService],

Optionally, you can configure the API routes with moleculer-web:

const { ApiGatewayService } = require('moleculer-web');
module.exports = {
mixins: [ApiGatewayService],
dependencies: ['ldp'],
async started() {
...(await this.broker.call('ldp.getApiRoutes')),
// Other routes here...
].forEach(route => this.addRoute(route));
