At the institute where I am working we have several rooms that are being used e.g. for teaching and exams. Currently, we don't have a system in place to manage the booking of these rooms.
I am searching for a free and open source system for calendar management that I can install on a simple webspace with a MySQL database. The system must allow to set up several calendars as well as to share them publicly and allow users to apply changes. Support of WebDAV would be a plus.
I suppose Nextcloud with its calendar plugin would do the job but maybe running a Nextcloud instance is a bit overengineered for my purpose.
