OCX brings the open source community to Brussels for three days of technical sessions, workshops and networking, across all tracks. Registration is handled on an external site, and you will need an Eclipse Foundation account to complete it.

  • Workshops and Birds of a Feather sessions.
  • Lunch is included.
