iCalendar Transport-Independent Interoperability Protocol

Overview

RFC 5546, “iCalendar Transport-Independent Interoperability Protocol”, is a Proposed Standard document published in December 2009 by C. Daboo. It updates RFC 5545. It obsoletes RFC 2446. It has since been updated by RFC 6638. The canonical text is published by the RFC Editor.

Abstract

This document specifies a protocol that uses the iCalendar object specification to provide scheduling interoperability between different calendaring systems. This is done without reference to a specific transport protocol so as to allow multiple methods of communication between systems. Subsequent documents will define profiles of this protocol that use specific, interoperable methods of communication between systems.

The iCalendar Transport-Independent Interoperability Protocol (iTIP) complements the iCalendar object specification by adding semantics for group scheduling methods commonly available in current calendaring systems. These scheduling methods permit two or more calendaring systems to perform transactions such as publishing, scheduling, rescheduling, responding to scheduling requests, negotiating changes, or canceling.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
