| File Description |
Web page created for mobile devices using the Handheld Device Markup Language (HDML); an extension of the SGML language, which is used for creating .SGML files; designed to be displayed on smartphones and other portable electronic devices.
HDML files can be viewed with compatible devices using the Openwave UP.Browser; they can be edited on a computer with a text editor, but are not supported by standard Web browsers.
HDML was introduced by Unwired Planet (now Openwave) in 1996; around 1999, HDML was replaced by the Wireless Markup Language (.WML), which was influenced by HDML. |
