Douglass Status: Standards Track Stream: IETF Date: August 2016 Mailbox: cyrus@daboo.name, mdouglass@sphericalcowgroup.com Pages: 24 Characters: 47971 Updates: RFC 4791, RFC 5545, RFC 6638 I-D Tag: draft-ietf-calext-availability-04.txt URL: https://www.rfc-editor.org/info/rfc7953 DOI: http://dx.doi.org/10.17487/RFC7953 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. This document is a product of the Calendaring Extensions Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
