The use of public traffic areas (streets, paths or squares) beyond common use requires a special use permit. This includes events on public paths (e.g. major events, street festivals and local residents' festivals).
If you want to have an event recorded, you must apply for this. There is no obligation to schedule an event. Scheduled events are exempt from certain requirements.
If you want to have an event scheduled, you must submit an application to the responsible authority. The schedule is voluntary, but scheduled events are exempt from certain legal requirements.
