Abstract
Web accessibility not only guarantees universal user access to the Web, but also provides interesting
benefits for Web development. In order to achieve the goal of Web accessibility, an interesting approach is
the incorporation of accessibility requirements into current Web engineering methods. This article presents
the Accessibility for Web Applications (AWA) approach with the aim of integrating accessibility into Web
engineering methods. The paper also discusses the application of the AWA approach to the Object-
Oriented Web Solutions (OOWS) engineering method to produce accessible Web applications with a focus
on navigational requirements. In order to demonstrate the practical applicability and usefulness of the
approach, a proof of concept is described, the results of which indicating the satisfaction of navigation
accessibility requirements. With the application of the AWA approach in the model-driven development
(MDD) method, previously-defined OOWS models have been extended with the accessibility criteria,
providing resources for the required changes in the process.
