Standard Generalized Markup Language - Standard Versions

Standard Versions

SGML is an ISO standard: "ISO 8879:1986 Information processing — Text and office systems — Standard Generalized Markup Language (SGML)", of which there are three versions:

  • Original SGML, which was accepted in October 1986, followed by a minor Technical Corrigendum.
  • SGML (ENR), in 1996, resulted from a Technical Corrigendum to add extended naming rules allowing arbitrary-language and -script markup.
  • SGML (ENR+WWW or WebSGML), in 1998, resulted from a Technical Corrigendum to better support XML and WWW requirements.

SGML is part of a trio of enabling ISO standards for electronic documents developed by ISO/IEC JTC1/SC34 (ISO/IEC Joint Technical Committee 1, Subcommittee 34 – Document description and processing languages) :

  • SGML (ISO 8879)—generalized markup language
    • SGML was reworked in 1998 into XML, a successful profile of SGML. Full SGML is rarely found or used in new projects.
  • DSSSL (ISO/IEC 10179)—document processing and styling language based on Scheme.
    • DSSSL was reworked into W3C XSLT and XSL-FO which use an XML syntax. Nowadays, DSSSL is rarely used in new projects apart from Linux documentation.
  • HyTime—Generalized hypertext and scheduling.
    • HyTime was partially reworked into W3C XLink. HyTime is rarely used in new projects.

SGML is supported by various technical reports, in particular

  • ISO/IEC TR 9573 – Information processing – SGML support facilities – Techniques for using SGML
    • Part 13: Public entity sets for mathematics and science
      • In 2007, the W3C MathML working group agreed to assume the maintenance of these entity sets.

Famous quotes containing the words standard and/or versions:

    “This unlettered man’s speaking and writing are standard English. Some words and phrases deemed vulgarisms and Americanisms before, he has made standard American; such as “It will pay.” It suggests that the one great rule of composition—and if I were a professor of rhetoric I should insist on this—is, to speak the truth. This first, this second, this third; pebbles in your mouth or not. This demands earnestness and manhood chiefly.”
    —Henry David Thoreau (1817–1862)

    “The assumption must be that those who can see value only in tradition, or versions of it, deny man’s ability to adapt to changing circumstances.”
    —Stephen Bayley (b. 1951)
