摘要：The aim of this paper is to review the best known methodologies for web
applications development as well as the existing supporting tools and techniques
from an accessibility-centric perspective. To this end, a number of development
methodologies with their respective characteristics are described: model-based
methodologies, user-centred processes, usability engineering methodologies and
accessibility engineering methodologies. Some of these methodologies are
provided with specific supporting tools which facilitate the accomplishment of
specified tasks. However, there are methodologies which are not supported by
specific tools. Therefore, web developers must deal with diverse tools in order
to perform the corresponding activities. In this context, the development of
accessible web applications is even more difficult. This paper concludes that
there is not currently a holistic development framework to be used throughout
the whole development process. Our contribution relies on a set of tools that
support the different phases of the process. Since these tools are developed
upon a common methodological basis, a high rate of interoperability is obtained.
This cohesion allows their integration in a comprehensive framework so that the
development of accessible web applications is facilitated.
