The IESG has approved the following document: - 'Non-Gregorian Recurrence Rules in iCalendar' (draft-ietf-calext-rscale-04.txt) as Proposed Standard This document is the product of the Calendaring Extensions Working Group. The IESG contact persons are Pete Resnick and Barry Leiba. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-calext-rscale/ Technical Summary This document defines how non-Gregorian recurrence rules can be specified, for example Chinese New Year, in iCalendar data and with CalDAV servers primarily by extending the RRULE property. It is a Proposed Standard and extends RFCs 5545 (iCalendar), 6321 (xCal), and 7265 (jCal). Review and Consensus The document was augmented and improved based on the discussion on the calsify mailing list, which the WG uses, of WG Last Call and the Shepherd review comments. Augmentations that were made to include extensions to xCal and jCal to handle the extended RRULE property. A moderate number of knowledgeable people chimed in and the document Shepherd believe review has been more than adequate. There was significant discussion about how the SKIP property should work, as different calendars and even different situations for the same calendar would demand different ways of skipping invalid dates/times and settling them onto valid ones. The result in the document represents consensus on the least problematic way of dealing with this.
