Technical direction and development on a project about a Drupal 7 website constellation for a health editor. Each magazine, dedicated to a medical specialism, has its own website. These are too different from one another to rely on the Domain Access module, however they share a great part of the code and the configuration. We agreed on a multi-site approach, all the sites sharing a common installation profile. Each feature is confined in a module (which relies on the Features contributed module), and can be enabled or not on a specific website.
Among the most technical points which were implemented, we can mention single sign-on (SSO) on a unique user database, and content migration from the former Drupal 6 instances with the Migrate module.
