Mircea Fernea will give a presentation on setting up a multilingual Drupal site for the European Year of Development 2015 project. The site was built with Drupal and included 23 languages with content contributed by over 200 partners. The technical design involved modules for content translation, taxonomy translation, language switching, and search to support contributions and content in multiple languages. Challenges included language fallback behavior and translating forms and webforms across languages.
