Opening up access to online documents using essentiality tracks

This paper discusses extensions to the previously developed “essentiality and proficiency” approach to increasing usability and accessibility of websites. The existing approach is introduced, as is a new application in the processing of Doc- Book XML documents. The current principles are extended to make them more appropriate for increasing the usability of long documents. Techniques for allowing organisations to efficiently disseminate information based on the proposed application are discussed – increasing productivity for both non-disabled and disabled users.
