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.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
