rdf-ext v1.2.2

Extended Linked Data module

RDF Interfaces Extension

Build Status npm version

RDF-Ext provides a JavaScript library for working with RDF & Linked Data. This module contains the core classes to handle RDF Model data. Additional modules may be required to handle data in different formats (Turtle, JSON-LD) or stores (Web, SPARQL). The module section lists the most common modules.


In general, consult the RDFJS specification for details about how to interact with the library.


RDF-Ext is available on npm, to install it run:

npm install rdf-ext

In the code, import RDF-Ext:

const rdf = require('rdf-ext')


The preferred way to use RDF-Ext in the browser is using browserify.


It's also possible to use a prebuilt or custom distribution using the RDF-Ext distribution builder. This can be also done using the RDF-Ext distribution builder site.

Than just import the RDF-Ext distribution:

<script src="/js/rdf-ext.js"></script>

Everything is attached to the global variable rdf.


Issues & feature requests should be reported on Github.

Pull requests are very welcome.
