A data-descriptive meta language file, such as XML, is created that defines the layout operation within the visual interface of a component-based application at runtime. At runtime, the application receives a data-descriptive meta language file that defines the layout operation of the various components within the application visual interface. The application parses the data-descriptive meta language file and uses the parsed information to complete the layout and operation of the rendered interface. The runtime application includes functionality that uses selected data to specify unique applications and/or unique content associated with the application.
