# Gutenberg RDF

Gutenberg RDF is a Ruby wrapper for the Project Gutenberg RDF catalog book files,
providing an API to all the metadata contained within.

The official RDF catalog can be found here: http://www.gutenberg.org/wiki/Gutenberg:Feeds


## Requirements

* Ruby 2.0 - this is so we get UTF-8 by default

NOTE: In around April 2014 PG changed the XML format in their RDF files
considerably, so this GEM will no longer work on files from before that date.
Please make sure to download the latest catalog using the link above.


## Installation

Add this line to your application's Gemfile:

    gem 'gutenberg_rdf'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install gutenberg_rdf
