1. Introduction

See the debian.ch bylaws, in english

2. The organization should share Debian's general visions

The organization's bylaws, activities and political stance should not conflict with the Debian Social Contract.

From the debian.ch bylaws, article 2:

Note that these bylaws were written under the earlier running state of debian.ch actually being a TO. These highlight that the intent behind the debian.ch association foundation was to explicitly be a representative of the Debian project and support it and its activities.

3. The organization should remain loyal to Debian

The organization should be considered fully trustworthy, or provide
guarantees that Debian's assets will be managed according to the Debian
Project's decisions.

From the debian.ch bylaws, article 5, about membership:

4. The organization should provide accountability on assets held in trust

5. The organization should be reliable, sustainable, and reactive

As for reliability and sustainability, debian.ch has been running since at least 2008 without interruption, with at least annual general meetings (AGMs) and other in-person meetings.

debian.ch has also launched and organized DebConf13.ch in Vaumarcus, which was conducted successfully.

As for reactiveness, the post-DebConf ambiance has hurt the reactiveness of debian.ch; the time it took to actually fill this TO criteria isn't great either, but this will most certainly get fixed over time.

6. The organization should provide a reasonable financial framework
