C. Daboo: AUTHOR [+2]


Calendar users often have regular periods of time when they are either available to be scheduled or always unavailable. For example, an office worker will often wish only to appear free to their work colleagues during normal 'office hours' (e.g., Monday through Friday, 9 am through 5 pm). Or, a university professor might only be available to students during a set period of time (e.g., Thursday afternoons, 2 pm through 5 pm during term time only). Ideally, users ought be able to specify such periods directly via their calendar user agent and have them automatically considered as part of the normal free-busy lookup for that user. In addition, it ought be possible to present different periods of available time depending on which user is making the request.

                          Calendar Availability


   This document specifies a new iCalendar (RFC 5545) component that    allows the publication of available and unavailable time periods    associated with a calendar user.  This component can be used in    standard iCalendar free-busy lookups, including the iCalendar    Transport-independent Interoperability Protocol (iTIP; RFC 5546)    free-busy requests, to generate repeating blocks of available or busy    time with exceptions as needed.

   This document also defines extensions to the Calendaring Extensions    to WebDAV (CalDAV) calendar access protocol (RFC 4791) and the    associated scheduling protocol (RFC 6638) to specify how this new    calendar component can be used when evaluating free-busy time.
