1.  Introduction

1.1.  Overview

   A number of technologies and applications provide the ability for a
   person to choose a memorable, human-friendly name in a communications
   context or to set such a name for another entity such as a device,
   account, contact, or website.  Such names are variously called
   "nicknames" (e.g., in chat room applications), "display names" (e.g.,
   in Internet mail), or "petnames" (see [PETNAME-SYSTEMS]); for
   consistency, these are all called "nicknames" in this document.

   Nicknames are commonly supported in technologies for textual chat
   rooms, such as:

   o  Internet Relay Chat (IRC) [RFC2811]

   o  The Message Session Relay Protocol (MSRP) [RFC4975] [RFC7701]

   o  Centralized Conferencing (XCON) [RFC5239] [XCON-SYSTEM]

   o  The Extensible Messaging and Presence Protocol (XMPP) [RFC6120]
      [XEP-0045]
