| Draft as of 2025-10-27 | Computable Name: SlotFreeTimeslots | |||
The SlotFreeTimeSlots profile is a Cambio profile, based on the profile SlotCore, with the intended use of reading time slots that are available for bookings.
The MustSupport-flag indicates which attributes are supported by Cambio, meaning that those can be returned as part of the slot.
