Definition

Noun: 1. (Computer Science) A Standardized Metalanguage for Document Markup: A system that defines a set of rules for creating and using markup languages to describe the structure and other attributes of a document. It is a meta-language, meaning it provides the framework for defining specific markup languages (like HTML or XML), rather than being a single markup language itself.

Usage Examples

• Noun:
  • The development of HTML was based on the principles of Standard Generalized Markup Language.
  • Before the rise of XML, Standard Generalized Markup Language was a key standard for document interchange in publishing and technical fields.

Advanced Usage

• As an Acronym (SGML): The term is almost exclusively used in its abbreviated form, "SGML," in technical and historical contexts.
  • The original web was built on SGML-derived languages.
  • Many complex document systems in government and industry were built on SGML.

Variants and Related Words
