Abstract

   This document registers the text/markdown media type for use with
   Markdown, a family of plain text formatting syntaxes that optionally
   can be converted to formal markup languages such as HTML.

1. Introduction

1.1. This Is Markdown! Or: Markup and Its Discontents

   In computer systems, textual data is stored and processed using a
   continuum of techniques. On the one end is plain text: a linear
   sequence of characters in some character set (code), possibly
   interrupted by line breaks, page breaks, or other control characters.
   The repertoire of these control characters (a form of in-band
   signaling) is necessarily limited, and not particularly extensible.
   Because they are non-printing, these characters are also hard to
   enter with standard keyboards.

   Markup offers an alternative means to encode this signaling
   information by overloading certain characters with additional
   meanings. Therefore, markup languages allow for annotating a document
   in such a way that annotations are syntactically distinguishable from
   the printing information. Markup languages are (reasonably) well-
   specified and tend to follow (mostly) standardized syntax rules.
   Examples of formal markup languages include SGML, HTML, XML, and
   LaTeX. Standardized rules lead to interoperability between markup
   processors, but impose skill requirements on new users that lead to
   markup languages becoming less accessible to beginners. These rules
   also reify "validity": content that does not conform to the rules is
