TiVA Profiler System

The web services offered by TiVA satisfy the following Web Content Accessibility Guidelines, recommended by the World Wide Web Consortium.

1. Provide equivalent alternatives to auditory and visual content.
   • Every non-text element has a text equivalent provided. This includes images, graphical representations of text, images used as list bullets and buttons.
   • Spacer graphics have been given a NULL ALT attribute.


2. Don't rely on colour alone.
   • All information conveyed with colour is also available without colour, for example from context or markup.
   • Foreground and background colour combinations provide sufficient contrast when viewed by someone having colour deficits or when viewed on a black and white screen.


3. Use markup and style sheets and do so properly.
   • When an appropriate markup language exists, markup is used rather than images to convey information.
   • Style sheets are used to control presentation.
   • Relative rather than absolute units in markup language attribute values and style sheet property values are used.
   • Header elements are used to convey document structure.
   • Lists and list items are marked up correctly.


4. Clarify natural language usage.
   • The primary natural language of the documents are identified.


5. Create tables that transform gracefully.
   • Data tables have row and column headers identified.
   • Tables used for layout makes sense when linearised.
   • Structural markup is not used for the purpose of visual formatting.


6. Ensure that pages featuring new technologies transform gracefully.
   • Documents are organised in such a way that they can be read without style sheets.


7. Use interim solutions.
   • Pop-ups or new windows are not opened without first warning the user.
   • All form labels are properly positioned.


8. Use W3C technologies and guidelines.
   • W3C technologies are used when they are available and appropriate for a task and the latest versions are used where supported.
   • Deprecated features of W3C technologies are avoided where possible.


9. Provide clear navigation mechanisms.
   • The target of each link is clearly identified through meaningful text.
   • Navigation mechanisms are used in a consistent manner.
   • Navigation bars are provided to highlight and access the navigational mechanism.


10. Ensure that documents are clear and simple.
    • The clearest and simplest language appropriate for the site's content is used throughout.
    • A style of presentation is used that is consistent across pages.
