XML

XML, aka Extensible Markup Language, is an open source data notation created in 1996 by Tim Bray and Jean Paoli and C. M. Sperberg-McQueen and Eve Maler and François Yergeau and John W. Cowan.

In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C's XML 1.0 Specification and several other related specifications—all of them free open standards—define XML. The design goals of XML emphasize simplicity, generality, and usability across the Internet. Read more on Wikipedia...
