This document describes the steps to use a prerelease of Comunica 2.x.

Intended release date: Somewhere in the week of Monday 28 February

Warnings:

• This is major update with breaking changes, which means that old invocations of Comunica will have to be changed slightly.
• The READMEs and documentation on comunica.dev have not been updated yet, so you will have to discover the usage of the new API via autocompletion of an IDE with TypeScript support.
• The Comunica prereleases depend on the new RDF/JS typings (@rdfjs/[email protected]).

Getting started:

rubensworks

const BindingsFactory = require('./packages/bindings-factory').BindingsFactory;
const DataFactory = require('rdf-data-factory').DataFactory;
const { sha1 } = require('hash.js');
const canonicalize = require('canonicalize');
const { termToString } = require('rdf-string');
const MurmurHash3 = require('imurmurhash');
const xxHash32 = require('js-xxhash').xxHash32;

const DF = new DataFactory();
const BF = new BindingsFactory(DF);
