Abstract:
This document specifies a new iCalendar calendar 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 iTIP free-busy
requests, to generate repeating blocks of available or busy time with
exceptions as needed.
This document also defines extensions to CalDAV calendar-access and
calendar-auto-schedule which specify how this new calendar component
should be used when doing free-busy time evaluation in CalDAV.
