This Technical Report defines a format for describing user interface objects@ actions and attributes. It provides a basis for standardizing the names and properties of user interface objects@ actions and attributes across multiple applications and platforms. NOTE User interface objects as defined and discussed in this Technical Report are not necessarily equivalent to objects in the software engineering sense. All elements of the user interface which are separately identifiable by the user can be considered to be user interface objects@ regardless of how they are technically implemented. This Technical Report focuses on their functionalities without specifying a particular method of implementation. This Technical Report contains guidance both on the standardization of user interface objects@ actions and attributes and on the implementation of these objects@ actions and attributes in any or all modalities. This Technical Report is primarily intended for developers of standards@ style guides@ and architectures involving user interface objects@ actions and attributes. EXAMPLE It is used as the basis for icon-specific accessibility guidance in ISO/IEC 19766. This Technical Report also provides software developers with a range of functionalities to be considered in the design of objects@ actions and attributes within user interfaces.
