This resource maintained by the Patient Administration Work Group
A slot of time on a schedule that may be available for booking appointments.
Slot resources are used to provide time-slots that can be booked using an appointment.
They do not provide any information about appointments that are available, just the time,
and optionally what the time can be used for. These are effectively spaces of free/busy time.
Slots can also be marked as busy without having appointments associated.
A slot can have more than one appointment allocated to it. A scheduling system may permit multiple allocations up to a specific number of places. An example of this type of usage could be where the slot is being used for a group service that permits 5 participants at the same time.
A slot can be marked as over-booked indicating that there are too many appointments allocated to it.
In some situations a service may have a specific set of slots reserved for specific uses, such
as "walk-ins" or a specific Organisation has a "standing booking" for Thursday mornings.
These should be represented using the type field with a specified and agreed value.
Security Permissions or specific business rules on the system could enforce that only eligible
appointments are allocated to them.
If a service had a weekly schedule created that permitted eight 1 hour appointments each
day of a working week (Monday - Friday), this would be constructed by a single Schedule
resource with the dates for the start and end of the week set, and then 40 (5x8) Slot
resources associated with it.
As appointments fill up the schedule, these slots would individually be marked as busy
as the appointments are filled into the slots.
The slots in a schedule do not need to be the same size, and can be different for different
days of the week.
Slot instances do not have any recurrance information included. If recurring information is
desired, this will be managed outside these resources, or included as extensions.

The strong desire is that implementers of this resource should consider providing this resource
in the iCalendar format as an alternative representation. Many 3rd party applications and component providers
have parsers and user interface controls to display this information.
This may lower the entry point to integrate outside the health-care specific applications, and into the
consumer space. This would permit the easier creation of a mobile application that creates appointments
in the devices native calendar.
The iCalendar specification can be found at http://www.ietf.org/rfc/rfc2445.txt.
