Markup

Markup can refer to:

Markup (legislation)

Markup (or mark-up) is the process by which a U.S. congressional committee or state legislative session debates, amends, and rewrites proposed legislation.

Markup in the House of Representatives

The process of marking up bills and resolutions in committees of the House of Representatives generally resembles, but does not perfectly replicate, the process of amending measures on the House floor.

At the beginning of a markup, committee members often make opening statements, usually not exceeding five minutes apiece. The first reading of the text of the bill to be marked up can be waived, either by unanimous consent or by adopting a nondebatable motion. The bill then is read for amendment, one section at a time, with committee members offering their amendments to each section after it is read but before the next section is read. By unanimous consent only, the committee may agree to dispense with the reading of each section, or to consider a bill for amendment by titles or chapters instead of by sections. Also by unanimous consent, the committee may consider the entire bill as having been read and open to amendment at any point.

Markup language

A markup language is a system for annotating a document in a way that is syntactically distinguishable from the text. The idea and terminology evolved from the "marking up" of paper manuscripts, i.e., the revision instructions by editors, traditionally written with a blue pencil on authors' manuscripts.

In digital media this "blue pencil instruction text" was replaced by tags, that is, instructions are expressed directly by tags or "instruction text encapsulated by tags." Examples include typesetting instructions such as those found in troff, TeX and LaTeX, or structural markers such as XML tags. Markup instructs the software that displays the text to carry out appropriate actions, but is omitted from the version of the text that users see.

Some markup languages, such as the widely used HTML, have pre-defined presentation semantics—meaning that their specification prescribes how to present the structured data. Others, such as XML, do not.

HyperText Markup Language (HTML), one of the document formats of the World Wide Web, is an instance of SGML (though, strictly, it does not comply with all the rules of SGML), and follows many of the markup conventions used in the publishing industry in the communication of printed work between authors, editors, and printers.
