ARCHIVED: What is SGML?
SGML (Standard Generalized Markup Language) is a language for defining markup languages such as HTML and for specifying the rules for tagging elements in a document. SGML itself is not a markup language; rather, it is a language to create markup languages. SGML supports the definition of markup languages that are hardware- and software-independent. SGML was developed and standardized by the International Organization for Standardization (ISO), which published it in 1986. Because of SGML's complexity, HTML and XML were developed as simplified subsets of SGML for use on the Internet.
