Your guide to navigate the EU Open Source Week!

Joining the EU Open Source Week this year? With this guide you won’t miss out on any of the open technology events and activities during your visit in Brussels!

Every year, at the end of January and the beginning of February, thousands of people from Europe and around the world gather in Brussels to discuss open source and open technologies. The main attraction is FOSDEM, Europe’s largest open source conference, which has inspired a range of side events, social activities, and workshops. For those interested in open technology, digital policy, and EU developments, OpenForum Europe’s EU Open Source Policy Summit brings together open source leaders and policymakers. Together, these events make up the EU Open Source Week.

Unconference and networking on several trains going to Brussels
Registration:
Registration required
Topic:
Travels
Visit website

The “event” is meant to coordinate several train routes to Brussels to bring hackers from all over Europe to FOSDEM and the Open Source Week. The intent is on both helping hackers organise their travel and being a means for meeting and socialising in smaller environments (trains) before reaching the main event that is FOSDEM.

The start date is just a guesstimate when the earliest HackerTrains will leave for Brussels. It is entirely up to the routes/groups to decide when they travel.

Previous attendees include developers from ORT, ScanCode, ClearlyDefined, FOSSology, Tern, FSFE REUSE, SW360, BANG, Hermine, Opossum, SPDX tools, DoubleOpen, OpenChain, and AboutCode projects along with users from leading technology and industrial companies, open source foundations, and government institutions worldwide. Whether you are a developer or user interested in the tools for Software Supply Chain and SBOMs, a FOSS license-savvy lawyer, a compliance or security analyst, or an OSPO member: you will be warmly welcomed.
