IrusAnalytics is a gem that provides a simple way to send analytics to the IRUS-UK repository agggregation service.

More information about IRUS-UK can be found at https://irus.jisc.ac.uk/r5/. In summary the IRUS-UK service is designed to provide article-level usage statistics for Institutional Repositories. To sign up and use IRUS-UK, please see the above link.

This gem was developed for use with a Hydra repository http://projecthydra.org/, but it can be used with any other Rails based web application.

Note: The University of Michigan have developed a new version of this Gem for IRUS R5 https://github.com/mlibrary/irus_analytics,

Add this line to your application's Gemfile:

gem 'irus_analytics'

And then execute:

$ bundle

Or install it yourself as:

$ gem install irus_analytics

Once you have the gem, run the following generator:

$ rails g irus_analytics

This will generate a configuration file that exists within config/initializers/irus_analytics.rb

IrusAnalytics.configuration.source_repository is used to configure the name of the source respository url (i.e. what the url for your repository) IrusAnalytics.configuration.irus_server_address is used to define the IRUS-UK server endpoint, this can be configured for the test version of the service.

The Irus analytics code is designed to be called after a download event has happened in your rails application. The following code needs adding to the Rails controller handles the content download.

A simple example...

class YourDownloadController < ApplicationController
  # You need to include the IrusAnalytics behaviour module
  include IrusAnalytics::Controller::AnalyticsBehaviour 

  after_filter :send_analytics, only: [:show]

  def show
    @id = params[:id] 
    # Your code
  end

  protected 

  #  You need to define this method for IrusAnalytics to use as the identifier (typically a OAI valid identifier)
  def item_identifier 
    @id
  end
end

Therefore in summary...

include IrusAnalytics::Controller::AnalyticsBehaviour  

after_filter :send_analytics, only: [:show]

def item_identifier
end

... needs adding to the relevant controller.

To be compliant with the IRUS-UK client requirements/recommendations this Gem makes use of the Resque https://github.com/resque/resque. Resque provides a simple way to create background jobs within your Ruby application, and is specifically used within this gem to push the analytics posts onto a queue. This means the download functionality within your application is unaffected by the send analytics call, and it provides a means of queuing analytics if the IRUS-UK server is down.

Note: Resque requires Redis to be installed

By installing this gem, your application should have access to the Resque rake tasks. These can be seen by running "rake -T", the list should include:-

rake resque:failures:sort 
rake resque:work
rake resque:workers

To start the resque background job for this gem use

QUEUE=irus_analytics rake environment resque:work
