Promoting accessibility by using metadata in the framework of a semantic-web driven CMS
Web content accessibility for impaired people has
been mainly addressed by the Web Content
Accessibility Guidelines (WCAG) developed by the
Web Accessibility Initiative (WAI) of the W3C
Consortium. Those guidelines have proved to be good
diagnostic means for testing accessibility for different
types of impairments, as well as for guiding the
development of accessible content. A further step
would be to promote discovery of material having
appropriate accessibility support, as well as the
adjustment of control and display of resources to meet
user accessibility needs and preferences [5]. The last
two challenges have been addressed by the IMS
Global Learning Consortium in the IMS-AccessForAll
(ACCMD) and the IMS Learner Information Profile
(ACCLIP) specifications. Although IMS has
approached both goals in a learning framework, both
accessibility specifications pay a special attention to
impaired users’ needs. As a first step, in this paper we
survey how far IMS accessibility specifications cover
WCAG, and discuss the convenience of extending it to
the whole WAI guidelines. Secondly, we argue how
accessibility could be considered as a key issue for
promoting reusability. We continue explaining why
using a semantic framework (such as the MPEG-7
semantic tool, RDF or OWL) for describing textual
and contextual information in a standardized manner
could promote both, accessibility and reusability.
Finally, we explain how some accessibility issues
have been already addressed by XimetriX’s ximDEX,
a semantic-web Content Management System (CMS).
We conclude proposing a plan to better integrate the
accessibility specifications and contextual description
tools into that CMS
