# rdf-vocab
Common OWL/RDFS Vocabularies for use with Ruby [RDF.rb][]

[![Gem Version](https://badge.fury.io/rb/rdf-vocab.png)](http://badge.fury.io/rb/rdf-vocab)
[![Build Status](https://travis-ci.org/ruby-rdf/rdf-vocab.png?branch=master)](http://travis-ci.org/ruby-rdf/rdf-vocab)

## Extensions
This gem extends `RDF::Vocabulary` with `#to_ttl`, `#to_jsonld`, and `#to_html` methods to create special-purpose vocabulary serializations. The HTML version is templated using a Haml template to allow output to be customized.

Also extends `RDF::Vocabulary::Format` with the `gen-vocab` command extension to the `rdf` executable.

## Installation

Add to your Gemfile

    gem "rdf-vocab"

then

    bundle install

## Usage

    require "rdf/vocab"

This will load all the vocabulary classes in the library.

Also adds the `gen-vocab` command to the `rdf` command-line executable to generate specifically generated output in Turtle, JSON-LD, and HTML+RDFa for either built-in or arbitrary vocabularies.

## Adding new vocabularies

* First, add an entry to `lib/rdf/vocab.rb`, the key names contained within
for guidance. For more information, see the documentation on
[RDF::Vocabulary](http://www.rubydoc.info/github/ruby-rdf/rdf/RDF/Vocabulary).
* Next, create an empty file in `lib/rdf/vocab` based on the key name for
your vocabulary. For example, if you've added the vocabulary `:foo`, create a
new empty file at `lib/rdf/vocab/foo.rb`.
* Run `rake gen_vocabs`.

## Contributing

This repository uses [Git Flow](https://github.com/nvie/gitflow) to mange development and release activity. All submissions _must_ be on a feature branch based on the _develop_ branch to ease staging and integration.

* Do your best to adhere to the existing coding conventions and idioms.
* Don't use hard tabs, and don't leave trailing whitespace on any line.
  Before committing, run `git diff --check` to make sure of this.
* Do document every method you add using [YARD][] annotations. Read the
  [tutorial][YARD-GS] or just look at the existing code for examples.
* Don't touch the `.gemspec` or `VERSION` files. If you need to change them,
  do so on your private branch only.
* Do note that in order for us to merge any non-trivial changes (as a rule
  of thumb, additions larger than about 15 lines of code), we need an
  explicit [public domain dedication][PDD] on record from you.
