Handheld Device Markup Language

Evolution of mobile web standards

The Handheld Device Markup Language ( HDML ) is a markup language that was intended to be displayed on handhelds , information devices , smartphones, etc. The language is similar to HTML , but is optimized for wireless devices and handhelds with small screens, such as PDAs , cell phones, etc.

The language was originally designed by Unwired Planet in 1996 , which became Phone.com and then Openwave . Although HDML was sent to the W3C for standardization, it was not declared a standard. Instead, the draft had a significant impact on the development and standardization of WML , which then practically replaced HDML. (However, HDML is still used in Japan by KDDI brands such as au , especially for mobile online banking solutions.)
