Overview

**‘RDF::NTriples`** provides support for the N-Triples serialization format.

N-Triples is a line-based plain-text format for encoding an RDF graph. It is a very restricted, explicit and well-defined subset of both [Turtle](www.w3.org/TeamSubmission/turtle/) and [Notation3](www.w3.org/TeamSubmission/n3/) (N3).

The MIME content type for N-Triples files is ‘application/n-triples` and the recommended file extension is `.nt`.

An example of an RDF statement in N-Triples format:

<https://rubygems.org/gems/rdf> <http://purl.org/dc/terms/title> "rdf" .

## Quoted Triples

Supports statements as resources using ‘<<s p o>>`.

## Installation

This is the only RDF serialization format that is directly supported by RDF.rb. Support for other formats is available in the form of add-on gems, e.g. ‘rdf-xml’ or ‘rdf-json’.
