GML was developed in 1969 and the early 2010s1970s by [[Charles Goldfarb]], [[Edward Mosher]] and [[Raymond Lorie]] (whose surname initials were used by Goldfarb to make up the term GML).<ref name="TheRootsOfSgml">{{cite web|url=http://www.sgmlsource.com/history/roots.htm|year=1996|title=The Roots of SGML - A Personal Recollection|author=Charles F.

Using GML, a document is [[Markup (computing)|marked up]] with tags that define what the [[Character (computing)|text]] is, in terms of [[paragraph]]s, [[Page header|header]]s, [[List (composition)|list]]s, [[Table (information)#Tables as features offered by application programs|table]]s, and so forth. The document can then be automatically formatted for various [[Peripheral device|device]]s simply by specifying a profile for the device. For example, it is possible to format a document for a [[laser printer]] or a line ([[dot-matrix printer|dot matrix]]) printer or for a screen simply by specifying a profile for the device without changing the document itself.
