What is "usixml"

UsiXML (USer Interface eXtensible Markup Language) is an XML-based markup language for defining user interfaces on computers.

UsiXML is a specification language for user interface design. It allows the designer to describe a user interface at different levels of abstraction. In other words, you can specify a UI in terms of: functionality ( task analysis), the object it manipulates, or in a more concrete way, user interface.

The UsiXML language is currently being submitted for a standardisation plan to the W3C.

Another work with the same purpose is UIML.
