The Open Source Conference 2025 will take place the 1st of October 2025 in Belval, Esch-sur-Alzette, Luxembourg, following a very successful first edition in 2024 in combination with the LibreOffice Conference. Open Source software, together with data sovereignty, form the basis to achieve Digital Sovereignty as an inclusive effort where all the participants cooperate to create the tools we need to protect our data, while sharing the technologies that improve everyone’s digital lives. This year’s main tracks provide the opportunity to share the experiences of those that have chosen to produce and implement Open Source tools and platforms that improve security, resilience and data protection.

During the day, there will be several talks focused on LibreOffice or by LibreOffice community members:

1. Open Innovation and Open Source in Schleswig-Holstein, by Sven Thomsen, CIO of the State of Schleswig-Holstein
2. Free your mayor! Digital transformation and free software in Échirolles, by Nicolas Vivant, IT Manager of the City of Échirolles
3. The foundation behind LibreOffice, by Florian Effenberger, Executive Director of The Document Foundation
4. This is how it works: Open Source as competitive factor in the private (and public?) sector, by Lothar Becker, Managing Director of .riess-applications

The LibreOffice Conference will start in a week from today with the Community Meeting, at the Faculty of Informatics of ELTE (Eötvös Loránd University) in Pázmány Péter stny. 1/C, 1117 Budapest. The building is just in front of the Danube on the historic Buda side, and can be easily reached either by walking or by public transportation from the city center in Pest, where you can find the majority of hotels and restaurants.

To reach the city from the airport, take Bus 100E which goes directly to downtown (Deák Ferenc tér). Buy and validate tickets directly on the bus using your bank card for the Budapest Pay&GO service. bkk.hu/en/travel-information/airport-express/

Inside the city use public transport (BKK): metro, tram, bus. Buy tickets from purple machines or use the BudapestGO mobile app (iOS, Android). bkk.hu/en/ The best deal is a 24h / 72h travel pass, which does not need validation at each trip. IMPORTANT: the travel pass is not valid for the airport bus!

Currency is Hungarian Forint (HUF). Cards are accepted almost everywhere, but also you may need some Forint cash from Correct Change, Exclusive Change, or Gold Change. Avoid Euronet ATMs, use instead ATMs at major Hungarian banks like OTP, K&H, Erste, UniCredit, Raiffeisen, or CIB.

Time zone is CEST (UTC+2). Electricity is 230V, with standard European plug.

The Survival Guide with more information will soon be available on the Conference website.
