We are developing a hub that integrates various groupware tools. We want to have a calendar that supports CalDAV. On top of the calendar-based permission management, that you have in the Nextcloud Calender for example, we also need event-based permissions. More precisely, all members of the group shall have the permission to see all events as well as the permission to create new events. However, the permission to edit and delete existing events shall be restricted to certain group members only (the creator of the event plus the group admins).
I did not find anything helpful in RFC 4791. Are event-based permissions even compatible with CalDAV?
