Europe
Open Source in Europe
It’s all over the place!
Big governments try
“The European Commission is placing open standards and open-source software at the
centre of its efforts to promote interoperable e-government services with a new working
paper introduced this month.” — ZDNet
Small governments do
“Nearly half of European local government bodies are using open source software while
nearly a third don’t know that they are using open source at all.” — The Register

Belgium
Open Source in Belgium
From the federal government to a huge conference
Open Standards for the future
From September 2008 onwards, all document exchanges within the services of the Belgian
Government will have to be in an open, standard format. Only ODF is accepted as such a
standard.
FOSDEM
“5000+ geeks, 200+ lectures, 2 days, 0 e”
Profoss
“Profoss wants to give a good idea of the whole ICT market and let you compare
traditional solutions to open source solutions. We take a pragmatic look at the market,
and you get the information you need!”

Schoten
Open Source in Schoten
Jan Verlinden is the man!
Didn’t go unnoticed
“Schoten adopted open source software within its server IT environment and replaced
numerous proprietary applications. According to the municipality, the migration was a big
success. Due to the new server environment, Schoten could not only reduce related IT
expenses but also increase productivity and operation ability.” — OSOR
An example for governments around the world.
“Wie smaalt over het kwakkelende opensource-project van de Duitse stad M¨nchen kan
u
voor een klinkend tegenvoorbeeld dichter bij huis terecht, in Schoten met name” — Zea
Partners
And we’re not the only ones proud of it.
