The Handheld Device Markup Language (HDML) is a markup language intended for display on handheld computers, information appliances, smartphones, etc.. It is similar to HTML, but for wireless and handheld devices with small displays, like PDA, mobile phones and so on.
It was originally developed in about 1996 by Unwired Planet, the company that became Phone.com and then Openwave. HDML was submitted to W3C for standardization, but was not turned into a standard. Instead it became an important influence on the development and standardization of WML, which then replaced HDML in practice. (Although HDML is still in use in Japan by KDDI brands such as au, especially for mobile banking solutions.)
Famous quotes containing the words device and/or language:
“One good reason for the popularity of “reductionism” among the philosophical outposts of the Western Establishment is that it can be, and is, used as a device for trying to take the wind, so to speak, out of the sails of Marxism.... In essence reductionism is a kind of anti-Marxist caricature of Marxist determinism. It is what anti-Marxists pretend that Marxist determinism is.”
—Claud Cockburn (1904–1981)
“Play for young children is not recreation activity,... It is not leisure-time activity nor escape activity.... Play is thinking time for young children. It is language time. Problem-solving time. It is memory time, planning time, investigating time. It is organization-of-ideas time, when the young child uses his mind and body and his social skills and all his powers in response to the stimuli he has met.”
—James L. Hymes, Jr. (20th century)
