The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types.
DocBook is a schema (available in several languages including RELAX NG, SGML and XML DTDs). It is particularly well suited to books and papers about computer hardware and software (though it is by no means limited to these applications).
HTML is the World Wide Web's core markup language. Originally, HTML was primarily designed as a language for semantically describing scientific documents. Its general design, however, has enabled it to be adapted, over the subsequent years, to describe a number of other types of documents and even applications.
Journal Article Tag Suite (JATS) is an application of NISO Z39.96-2024, which defines a set of XML elements and attributes for tagging journal articles and describes three article JATS. models is a continuation of the NLM Archiving and Interchange DTD work begun in 2002 by NCBI.
Markdown is a lightweight markup language for creating formatted text using a plain-text editor. John Gruber created Markdown in 2004 as an easy-to-read pmarkup language.[9] Markdown is widely used for blogging and instant messaging, and also used elsewhere in online forums, collaborative software, documentation pages, and readme files.
Markless is a new markup standard that focuses on being intuitive and fast to parse. Being a purely text-based markup, no complicated editor software is required to create documents in it. With its focus on intuition and consistency it should also be a good fit as a markup choice for text based platforms such as chat, forums, etc. Markless does not specify its results based on another document format, meaning that an implementation could be written to turn a Markless document into practically any other format. Markless is strict and does not allow for any ambiguities in its markup. This both makes it less confusing for the user, and easier to parse for a program. Being based on a specification rather than a reference implementation, Markless also offers the users a much more stable and reliant source to turn to in case of questions about the behaviour of an implementation.
microformats are HTML for marking up people, organizations, events, locations, blog posts, products, reviews, resumes, recipes etc. Sites use microformats to publish a standard API that is consumed and used by search engines, browsers, and other web sites. See what-are-microformats for more.
A GNU Emacs major mode for keeping notes, authoring documents, computational notebooks, literate programming, maintaining to-do lists, planning projects, and more — in a fast and effective plain text system.
ReSpec makes it easier to write technical documents. It was originally designed for writing W3C specifications, but now supports many output formats.
The Text Encoding Initiative Consortium (TEI-C) is an international organization whose mission is to develop and maintain guidelines for the digital encoding of literary and linguistic texts. The Consortium publishes the Text Encoding Initiative Guidelines for Electronic Text Encoding and Interchange: an international and interdisciplinary standard that is widely used by libraries, museums, publishers, and individual scholars to represent all kinds of textual material for online research and teaching.
XSLTdoc is a Javadoc-like tool for documenting XSLT. The XSLTdoc tool defines conventions for documenting XSLT source files. The tool extracts these comments and builds documentation as a set of HTML pages. The documentation includes pages that display the XSLT source code with syntax highlighting, among many other features.
