MultiMarkdown is a lightweight markup language created by Fletcher T. Penney as an extension of the Markdown format. It supports additional features not available in plain Markdown syntax.5

There is also a text editor with the same name that supports multiple export formats.6

File format description

The MultiMarkdown language adds the following features to the basic Markdown specification:78

  • footnotes
  • tables
  • citations and bibliography (works best in LaTeX using BibTeX)9
  • math support
  • automatic cross-referencing ability
  • smart typography, with support for multiple languages
  • image attributes
  • table and image captions
  • definition lists
  • glossary entries (LaTeX only)
  • document metadata (e.g. title, author, date, etc.)

Software

There are a series of open-source interactive and automated software tools for editing and conversion to XML, HTML, and LaTeX10 that share the same name as the format.11 Several other open-source and commercial text editors, such as Scrivener, also include broad MultiMarkdown support.12
