Abstract User Interface Markup Language

The ever increasing variety of devices available to users means that it is not economically viable to develop tailored user interfaces for each device. This paper describes an XML Vocabulary, Abstract User Interface Markup Language (AUIML), which has been developed to allow some classes of interactive application to be developed once and adapted to run on a wide variety of device types. The language does not take the lowest common denominator approach while using abstraction to describe the user interface. This allows device dependent adaptation to take place when rendering.
