List of document markup languages

• HyperText Markup Language (HTML) – an ad hoc markup language that was originally created for the World Wide Web, took inspiration from the metalanguage SGML, and inspired many other markup languages
• Keyhole Markup Language (KML/KMZ) – an XML-based markup language used to exchange geographic information, originally, for use with Google Earth and, now also, other map programs
• Markdown – a simple, plain text markup language with multiple implementations, popular on blogs and content management systems
• Mathematical Markup Language (MathML) – a part of the HTML5 standard, an XML-based markup language used to describe mathematical notations as well as capturing their structure and content, intended to integrate mathematical formulae in the World Wide Web and other documents
• Scalable Vector Graphics (SVG) – an XML-based vector image format for defining two-dimensional graphics that has support for animations and interactive content
• TeX, LaTeX – a format for describing complex types and page layouts that is often used for mathematical, technical, and academic publications
• Wiki markup – one of a number of often lightweight markup languages used on wikis such as Wikipedia or WikiWikiWeb
• Extensible 3D (X3D) – a set of graphics file formats for declaratively representing 3D computer graphics that has support for interactive, network-capable content
• Extensible HyperText Markup Language (XHTML) – a markup language that mirrors HTML, written in the XML syntax
  • XHTML Basic – a subset of XHTML for simple (typically mobile, handheld) devices, meant to replace the Wireless Markup Language (WML) and Compact HTML (C-HTML) markup languages, as well as XHTML's own Mobile Profile (XHTML MP)

Metalanguages

• Standard Generalized Markup Language (SGML) – a metalanguage used to describe markup languages, of which XML and DocBook, as well as versions of HTML prior to HTML5 adhere to
• Extensible Markup Language (XML) – now the base of hundreds of other markup languages and document formats, an application and more restrictive subset of SGML that was designed to be easier to implement than a full SGML parser
