SIMPLE Made Simple: An Overview of the IETF Specifications
for Instant Messaging and Presence Using
the Session Initiation Protocol (SIP)
Abstract
The IETF has produced many specifications related to Presence and
Instant Messaging with the Session Initiation Protocol (SIP).
Collectively, these specifications are known as SIP for Instant
Messaging and Presence Leveraging Extensions (SIMPLE). This document
serves as a guide to the SIMPLE suite of specifications. It
categorizes the specifications, explains what each is for, and how
they relate to each other.

1. Introduction
The IETF has produced many specifications related to Presence and
Instant Messaging with the Session Initiation Protocol (SIP)
[RFC3261]. Collectively, these specifications are known as SIP for
Instant Messaging and Presence Leveraging Extensions (SIMPLE). These
specifications cover topics ranging from protocols for subscription
and publication to presence document formats to protocols for
managing privacy preferences. The large number of specifications can
make it hard to figure out exactly what SIMPLE is, what
specifications cover it, what functionality it provides, and how
these specifications relate to each other.

RFC 6914 Simple Made Simple April 2013
This document serves to address these problems. It provides an
enumeration of the protocols that make up the SIMPLE suite of
specifications from IETF. It categorizes them into related areas of
functionality, briefly explains the purpose of each, and how the
specifications relate to each other. Each specification also
includes a letter that designates its category [RFC2026]. These
