Abstract

   This document specifies the "about" URI scheme, that is widely used
   by Web browsers and some other applications to designate access to
   their internal resources, such as settings, application information,
   hidden built-in functionality, and so on.

1. Introduction

   This document specifies the "about" Uniform Resource Identifier (URI)
   scheme, that is currently widely used by Web browsers and some other
   applications to designate access to their internal resources, such as
   settings, application information, so called "Easter eggs" (i.e.
   hidden feature or joke in an application), and so on.

   The concept of "about" URIs has been formed at the times when the
   applications did not have the "friendly" user interface, in order to
   provide an access to the aforementioned resources via typing the URIs
   in the address bar.  Even though the user interface of current
   Internet-targeted software effectively rescinds the issue, and
   "about" URIs can be thought to be a rudimentary phenomenon, they are
   still supported by a variety of Web browsers and are not going to
   cease to exist.

   As use of "about" URIs has been quiet long-lasting, and the URIs have
   been used without any proper registration and absent any proper
   specification, the necessity for the the latter two actions arises. 
   The purpose of this document is to provide a stable specification for
   "about" URI scheme and correspondingly register it in the IANA
