Software

 Demosphere is a free and Open Source software for web calendars. It offers both a public interface (frontend) and an extensive management interface (backend) that moderators use to find and enter events. Demosphere can be considered as a productivity tool for finding and managing large numbers of events coming from many different sources.

 Frontend: features a main calendar view, an interactive map of events, configurable widgets to display custom calendars on other websites, configurable RSS feeds, configurable event email subscriptions, custom selection of events, a user-friendly public event form, ...

 Backend: Finding, selecting and entering events is a large amount of work. For example, the Paris site requires 3 hours of work every day. To make this work easier, we have developed many tools:

  • a (simple) mail reader for automatically finding events and duplicates in high volume mailing-lists.
  • a feed aggregator that helps find events and duplicates among articles published on other websites.
  • a "page watch" component that tells you when another web site has changed, helping you check if they have published an event.
  • a Firefox extension that highlights the upcoming dates and keywords on web pages, allowing to easily create new events from any page on the web.
  • several other tools that make life easier for moderators

 Demosphere-1 was based on Drupal. Demosphere-2, released in May 2013, no longer uses Drupal.
