RDF Interfaces Extension

This module implements [RDF-Ext] (http://bergos.github.com/rdf-ext-spec/), parsers (JSON-LD, RDF-XML, Turtle), serializers (JSON-LD, N-Triples, Turtle) and stores (in memory, LDP, SPARQL).

RDF-Ext requires a library which implements the RDF-Interfaces API. Here is a list of known working implementations:

• [reference implementation] (https://github.com/bergos/rdf-interfaces)
• [rdf] (https://github.com/Acubed/node-rdf)
• [rdfstore-js] (https://github.com/antoniogarrote/rdfstore-js)

Usage

node.js

Import your favourite RDF Interfaces library:

var rdf = require('rdf-interfaces');

Mixin RDF Interfaces Extension to the RDF Environment:

require('rdf-ext')(rdf);

Browser

Import your favourite RDF Interfaces library:

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

If you want to use the Turtle or JSON-LD parser:

<script src="/js/n3-browser.js"></script>
<script src="/js/jsonld.js"></script>

Because rdfstore-js comes with an outdated version of jsonld it must be deleted afterwards:

<script src="/js/rdfstore.js"></script>
<script>delete jsonld;</script>

Now you can import RDF-Ext:

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

Implementations

InMemoryStore

A simple in memory triple store implementation.

LdpStore

Store implementation to access graphs with RESTful interface.

RdfstoreStore

Store based on [rdfstore-js] (https://github.com/antoniogarrote/rdfstore-js).

SingleGraphStore

In memory triple store using a single graph for all named graphs. Sometimes usefull for testing.

SparqlStore

Store implementation to access graph with HTTP/SPARQL interface.

JsonLdParser

Parser for JSON-LD using the standard [JSON-LD library] (https://github.com/digitalbazaar/jsonld.js).

RdfXmlParser

Parser for RDF-XML data using a fork of the [rdflib.js] (https://github.com/linkeddata/rdflib.js) parser.

TurtleParser

Turtle parser using [N3.js] (https://github.com/RubenVerborgh/N3.js).

JsonLdSerializer

JSON-LD serializer exports expanded JSON-LD data.

NTriplesSerializer

N-Triples serializer using the RDF-Ext Graph.toString() function.
