So in two weeks (working like maniacs) we managed to create and set up a pretty cool system to provide a platform for festivals which have different events that spawns in multiple places at different time.
Right now the platform powers the first happening of the E-LuminateFestival. It is built using Django, no, not this Django, this Django, it uses Leaflet for the map integration, using the geographical data from OpenStreetMap. It’s mobile friendly with the use of Bootstrap and some help from us as well.
The events can be submitted only by participants who are approved by the administrator of the site. The code is available under GPL, but if you want us to set it up and tailor it for your event, just give us a shout.
