IrusAnalytics is a gem that provides a simple way to send analytics to the IRUS repository aggregation service.
More information about IRUS can be found at https://irus.jisc.ac.uk/r5/. In summary the IRUS service is designed to provide item-level usage statistics, both for Investigations (views) and Requests (downloads), for Institutional Repositories. To sign up and use IRUS, please see the above link.
This gem was developed for use with a Hyrax repository http://samvera.org/, but it can be used with any other web application supporting Ruby gems.
More information on COUNTER reports and reporting can be found at Project COUNTER
Blacklight OAI Provider or some other method of displaying an OAI feed of your works or digital objects. While the irus_analytics gem will push limited usage data to IRUS, they still need a way to harvest your repository metadata (like Title, Author, etc) to create COUNTER usage reports.
Add this line to your rails application Gemfile:
gem 'irus_analytics', git: 'https://github.com/JiscSD/irus_analytics'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install irus_analytics
Once you have the gem, run the following generator:
$ bundle exec rails generate irus_analytics:config
Or:
$ rails g irus_analytics:config
This will generate editable configuration and translation files in the config folder.
This uses a similar mechanism to the standard rails database.yml file to allow for per-environment configuration of the values for:
source_repository
is used to configure the name of the source respository url (i.e. what the url for your repository)
irus_server_address
is used to define the IRUS server endpoint, this can be configured for the test version of the service.
robots_file
is used to specify the name of the file containing the robot UserAgents as regular expressions.

The IrusAnalytics code is designed to be called after an Investigation (view) or Request (download) event has happened in your application. The following code added to the Rails controller handles the content download.
To add request handling to a controller, run the following:
Note: options are sent as single string, space separated options, option_name:value
type:investigation or type:request
after_action:show
controller_class_name:Hyrax::DissertationsController
Inject Request controller hooks (test mode)
bundle exec rails generate irus_analytics:inject_controller_hooks "type:request after_action:zip_download controller_class_name:Hyrax::DissertationsController test_mode:true"
Inject Investigation controller hooks (test mode)
bundle exec rails generate irus_analytics:inject_controller_hooks "type:investigation after_action:show controller_class_name:Hyrax::DissertationsController test_mode:true"
Inject Request controller hooks
bundle exec rails generate irus_analytics:inject_controller_hooks "type:request after_action:zip_download controller_class_name:Hyrax::DissertationsController"
Inject Investigation controller hooks
bundle exec rails generate irus_analytics:inject_controller_hooks "type:investigation after_action:show controller_class_name:Hyrax::DissertationsController"
A simple example of before and after of running both Investigation and Request generators against Hyrax::DissertationsController:
Before
# frozen_string_literal: true
module Hyrax
# Generated controller for Dissertation
class DissertationsController < DeepblueController
# Adds Hyrax behaviors to the controller.
include Hyrax::WorksControllerBehavior
#include Hyrax::BreadcrumbsForWorks
self.curation_concern_type = ::Dissertation
# Use this line if you want to use a custom presenter
self.show_presenter = Hyrax::DissertationPresenter
end
end
After
# frozen_string_literal: true
module Hyrax
# Generated controller for Dissertation
class DissertationsController < DeepblueController
# Adds Hyrax behaviors to the controller.
include Hyrax::WorksControllerBehavior
# begin inject IrusAnalytics::InjectControllerHooksGenerator: include IrusAnalytics controller behavior
include IrusAnalytics::Controller::AnalyticsBehaviour
# end inject IrusAnalytics::InjectControllerHooksGenerator: include IrusAnalytics controller behavior
# begin inject IrusAnalytics::InjectControllerHooksGenerator: IrusAnalytics after action
after_action :send_irus_analytics_request, only: [:zip_download]
# end inject IrusAnalytics::InjectControllerHooksGenerator: IrusAnalytics after action
# begin inject IrusAnalytics::InjectControllerHooksGenerator: IrusAnalytics after action
after_action :send_irus_analytics_investigation, only: [:show]
# end inject IrusAnalytics::InjectControllerHooksGenerator: IrusAnalytics after action
public
# begin inject IrusAnalytics::InjectControllerHooksGenerator: item_identifier_for_irus_analytics
def item_identifier_for_irus_analytics
# return the OAI identifier
# http://www.openarchives.org/OAI/2.0/guidelines-oai-identifier.htm
CatalogController.blacklight_config.oai[:provider][:record_prefix] + ":" + params[:id]
end
# end inject IrusAnalytics::InjectControllerHooksGenerator: item_identifier_for_irus_analytics
# begin inject IrusAnalytics::InjectControllerHooksGenerator: skip_send_irus_analytics?
def skip_send_irus_analytics?(usage_event_type)
# return true to skip tracking, for example to skip curation_concerns.visibility == 'private'
case usage_event_type
when 'Investigation'
false
when 'Request'
false
end
end
# end inject IrusAnalytics::InjectControllerHooksGenerator: skip_send_irus_analytics?
#include Hyrax::BreadcrumbsForWorks
self.curation_concern_type = ::Dissertation
# Use this line if you want to use a custom presenter
self.show_presenter = Hyrax::DissertationPresenter
end
end
Therefore in summary...
include IrusAnalytics::Controller::AnalyticsBehaviour
after_filter :send_analytics, only: [:show]
def item_identifier_for_irus_analytics
CatalogController.blacklight_config.oai[:provider][:record_prefix] + ":" + params[:id]
end
... needs adding to the relevant controller.
NOTE: If you are not using the Blacklight OAI Provider gem to create your OAI feed, you'll need to modify the item_identifier_for_irus_analytics method to conform with your application's OAI identifiers.
To be compliant with the IRUS 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 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
In a Hyrax application, the Hyrax::DownloadsController and Hyrax::FileSetsController will be in the Hyrax gem itself so the irus_analytics generator will not write to them. One can copy the entirety of these classes (and relevent specs) into one's application or can use the Module#Prepend pattern to add/modify the neccessary methods. An example for how to do this in Hyrax for a Presenter (but the idea is the same for Controllers) is here, https://samvera.github.io/patterns-presenters.html#overriding-and-custom-presenter-methods, or try something like:
# app/controllers/concerns/download_override.rb (or whatever convention you use)
Hyrax::DownloadsController.class_eval do
prepend(DownloadsControllerBehavior = Module.new do
include IrusAnalytics::Controller::AnalyticsBehaviour
# Render the 404 page if the file doesn't exist.
# Otherwise renders the file.
def show
case file
when ActiveFedora::File
# For original files that are stored in fedora
send_irus_analytics_request
super
when String
# For derivatives stored on the local file system
send_local_content
else
raise Hyrax::ObjectNotFoundError
end
end
def item_identifier_for_irus_analytics
# return the OAI identifier
CatalogController.blacklight_config.oai[:provider][:record_prefix] + ":" + FileSet.find(params[:id]).parent.id
end
end
end
where we add the item_identifier_for_irus_analytics method which reports the parent's or work's OAI identifier and we explicitly call the send_irus_analytics_request method only for Fedora downloads, not for derivatives like thumbnails since those are explicitly not considered Requests per COUNTER.
And then in application.rb something like:
config.to_prepare do
# ensure overrides are loaded
# see https://bibwild.wordpress.com/2016/12/27/a-class_eval-monkey-patching-pattern-with-prepend/
Rails.configuration.cache_classes ? require("app/controllers/concerns/download_override.rb") : load("app/controllers/concerns/download_override.rb")
