Build Status

iQvoc is a vocabulary management tool that combines easy-to-use human interfaces with Semantic Web interoperability.

iQvoc supports vocabularies that are common to many knowledge organization systems, such as:

  • Thesauri
  • Taxonomies
  • Classification schemes
  • Subject heading systems

iQvoc provides comprehensive functionality for all aspects of managing such vocabularies:

  • import of existing vocabularies from a SKOS representation
  • multilingual display and navigation in any Web browser
  • editorial features for registered users
  • publishing the vocabulary in the Semantic Web

iQvoc is built with state-of-the-art technology and can be easily customized according to user's needs.



You can easily setup your iQvoc instance in under 5 minutes, we wanted to make this process really easy.

To run iQvoc on heroku do the following:

bundle install
bundle exec heroku create --stack bamboo
bundle exec rake heroku:config
git push heroku master
bundle exec heroku rake db:migrate
bundle exec heroku rake db:seed
bundle exec heroku restart

heroku open opens your app in the browser.

Remember to visit the Users section and change the default passwords!

Remarks: For now iQvoc only supports the standard Bamboo stack. Cedar is not supported as we have sqlite3 as a dependency in the Gemfile and Cedar does not support a custom BUNDLE_WITHOUT config like Bamboo at the moment.


We recommend running iQvoc as a Rails engine. Running the cloned source code is possible but any modifications would require a fork.

  1. Configure your database via config/database.template.yml. Don't forget to rename it to database.yml
  2. Run bundle install
  3. Run bundle exec rake db:create to create the database
  4. Create the necessary tables by running rake db:migrate
  5. Load some base data by running rake db:seed
  6. Run bundle exec rake setup:generate_secret_token
  7. Boot up the app using bundle exec rails s (or passenger start if you use passenger)
  8. Log in with "admin@iqvoc" / "admin" or "demo@iqvoc" / "cooluri" (cf. step #5)
  9. Visit the Users section and change the default passwords


iQvoc is fully compatible with Ruby 1.9.2, 1.8.7 and JRuby 1.6.


There are many hooks providing support for your own classes and configuration. The core app also works as a Rails Engine. The config residing in lib/iqvoc.rb provides a basic overview of the possibilities.


Documentation resources can be found in the wiki.
