The IESG has received a request from the Calendaring Extensions WG (calext) to consider the following document: - 'Calendar Availability' <draft-ietf-calext-availability-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-07-07. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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 can be used when doing free-busy time evaluation in CalDAV. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-calext-availability/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-calext-availability/ballot/ No IPR declarations have been submitted directly on this I-D.
