Attendance numbers at DrupalCon conferences have dramatically increased over the past several years, so the non-profit Drupal Association decided to invest in the Conference Organizing Distribution (COD) as a standardized platform for building DrupalCon sites. The Drupal Association hired GVS to add several new features to COD, and support the local DrupalCon Chicago site-building team, staffed by Palantir.net.
The DrupalCon Chicago site features a highly versatile schedule, and a Birds of a Feather (BoF) scheduling tool that allows attendees to self-schedule their own informal sessions into designated slots in the session calendar.
The site also features organizer-curated sessions, as well as session proposals and community voting, to help select additional sessions. Attendees can filter the lists of sessions by Track, Skill level and keywords, and create a personalized schedule of sessions.
One of the site requirements was integration with the RegOnline registration system. GVS built and released the RegOnline API module. While Drupal has great tools for selling tickets and managing attendee data, it's great to have more options for integration with third party services if that is required by a particular event.
Following the success of the DrupalCon Chicago site, future Drupalcon teams are using COD to build the sites for the upcoming London 2011 and Denver 2012 DrupalCon websites.
