The two main open standards for descriptive mark-up are SGML (Standard Generalized Markup Language), published as a Standard by the International Standards Organization (ISO) in 1986, and XML (Extensible Markup Language), which was published as a Recommendation of the World Wide Web Consortium (W3C) in 1998. | Information Management Resource Kit Module on Management of Electronic Documents UNIT 2.
