Since 2001, the Free and Open source Software Developers' European Meeting (commonly known as FOSDEM) is an annual 2-day event hosting talks, tutorials, and stalls for the free software community. It is organised by volunteers at the Université Libre de Bruxelles in Belgium every year at the end of February.
Access to all parts of FOSDEM is free, but donations and sponsors are requested to help fund the event. In 2004 it was attended by 2500 people.
In addition to the main schedule, rooms are provided for individual projects to hold discussions.
It has been the venue for the Free Software Foundation's Award for the Advancement of Free Software since 2001 although 2006 was an exception. Richard Stallman has given one of the keynotes nearly every year.
The event in 2001 was Open Source Developers European Meeting. Its current name was adopted in 2002.
