The Writing and Learning Communities (WLC) system manages the workflow for anonymous peer-reviewed assignments.
The WLC system is a typical Ruby on Rails application. We use Capistrano to manage installation from the repository. See config/deploy.rb for our settings. The only step we do by hand at the moment is changing the owner of the public/stylesheets directory so that the Sass compiler can create an updated styles.css file.
To create the schema, run rake db:setup. This will also install seed data.
The relative trust calculation requires the Ruby-GSL library to do the required matrix calculations.
