<p>This document specifies a protocol that uses calendar objects 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. Other documents define profiles of this protocol that use specific, interoperable methods of communication between systems.</p> <p>The iCalendar Transport-Independent Interoperability Protocol (iTIP) complements the calendar object specifications 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.</p>

<p>This document defines an extension to CalDAV that allows clients and servers that audit data on the server, to provide feedback based on the results of such audits. This can be used to signal clients about junk events, or other inappropriate content. It can also be used by clients to provide feedback about junk events, or other inappropriate content, that the server can act on in a manner that prevents the originator of the data from knowing it was discarded.</p>
