Open Source

In today's networked world, open systems are essential for smooth communication. This is the only reason why services such as the World Wide Web or e-mail have become successful. Open source software is a central component of this movement and helps companies, public administrations, schools and private individuals to concentrate on their central tasks independently of external constraints.

Open Business

Open source should also be spread in the business world. Open Business serves as an approach to using open ideas and open content.

Open Community

CH Open is also active behind the scenes and is involved in commissions and activities such as eCH and swissICT for Open Source Software, Open Business und Open Society.

Engagement of CH Open

Working Groups

CH Open offers numerous national conferences and events (Working Groups) around the topic of Open Source. The theoretical and practical expertise of CH Open members and interested parties should thus be expanded in the area of open source software, but also in related areas such as open data, open government, open innovation and more.

The CH Open Business Events are also part of the Working Groups. They take place several times a year in Swiss cities.

Together with the Forschungsstelle Digitale Nachhaltigkeit an der Universität Bern CH Open also launches and publishes research projects in the field of open source.

Other events

CH Open organises the working groups itself or participates in third-party events. These include: Open Education Day, IT-Beschaffungskonferenz, Workshop-Tage, DINAcon and others.

The association is also involved in commissions or working groups in associations such as eCH, swissICT, Opendata.ch, Digitale Gesellschaft and others. Politically, the association is involved and represented by the Parlamentarischen Gruppe für Digitale Nachhaltigkeit.
