[Acronym] for __S__tandard __G__eneralized __M__arkup __L__anguage. ---- From http://whatis.techtarget.com/definition/0,,sid9_gci214201,00.html: SGML (Standard Generalized Markup Language) is a standard for how to specify a document markup language or tag set. Such a specification is itself a document type definition ([DTD]). SGML is not in itself a document language, but a description of how to specify one. It is metadata SGML is based on the idea that documents have structural and other semantic elements that can be described without reference to how such elements should be displayed. The actual display of such a document may vary, depending on the output medium and style preferences. Some advantages of documents based on SGML are: * They can be created by thinking in terms of document structure rather than appearance characteristics (which may change over time). * They will be more portable because an SGML compiler can interpret any document by reference to its document type definition ([DTD]). * Documents originally intended for the print medium can easily be re-adapted for other media, such as the computer display screen. The language that this Web browser uses, Hypertext Markup Language ([HTML]), is an example of an SGML-based language. There is a document type definition for HTML (and reading the HTML specification is effectively reading an expanded version of the document type definition). SGML is based somewhat on earlier generalized markup languages developed at [IBM], including General Markup Language (GML) and ISIL. ----- [XML] is a simplified version of [SGML] when the discovered that noone understood [SGML], and only used a handful of features.
