In computing, a simplified subset of
SGML for defining languages for specific purposes or specific industries for use on the World Wide Web. XML is more powerful than
HTML, because the formatting tags are user-defined, but less cumbersome than SGML. XML has been developed through the W3 Consortium, who published XML 1.0 in December 1997.
XML provides the last piece of technology required to develop truly portable applications. The Internet provides the global network,
Java provides portable programs, and XML enables programmers to create portable data.
