Install Ruby & Linkeddata Gem

sudo apt-get install ruby

sudo apt-get install ruby-dev

sudo apt-get install zlib1g-dev libreadline-dev libssl-dev libcurl4-openssl-dev

sudo gem install linkeddata

Successfully installed htmlentities-4.3.3
Fetching: rdf-xsd-1.1.3.gem (100%)

	For best results, use nokogiri and equivalent-xml gems as well.
	These are not hard requirements to preserve pure-ruby dependencies.

HEADS UP! Haml 4.0 has many improvements, but also has changes that may break
your application:

* Support for Ruby 1.8.6 dropped
* Support for Rails 2 dropped
* Sass filter now always outputs <style> tags
* Data attributes are now hyphenated, not underscored
* html2haml utility moved to the html2haml gem
* Textile and Maruku filters moved to the haml-contrib gem
