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 and Notation3 (N3).

The MIME content type for N-Triples files is text/plain and the recommended file extension is .nt.

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

<http://rubyforge.org/> <http://purl.org/dc/terms/title> "RubyForge" .

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'.
