Conclusion
Final discussion
In "Accessibility, usability and adaptability: responding
to Dublin Core Profiles of Needs and Preferences", the
authors assert:
.. the newly emerging IMS and Dublin Core adaptability
and accessibility standards and the proposed profiles of
needs and preferences (PNP) is set to have a profound impact
on the way we view the creation of digital content as well
as the way it is presented to us (Green
S, ???, p. 18).
This thesis has worked its way through a maze of issues to
justify a simple contention stated at the beginning:
Considering the problems of accessibility,
the context in which the problem occurs, and the available
solutions, it has been necessary to define a more comprehensive
framework in which the available parts can function, taking
better advantage of the emerging technologies, without compromising
either the interests of stakeholders or existing efforts,
to achieve a better outcome for users and publishers.
The thesis has followed the structure proposed in the diagram,
also shown earlier:
It has been shown that given the newer technologies and techniques,
including what is known as Web 2.0 technologies and metadata,
it is possible to be more comprehensive in the approach to
accessibility without compromising hard-won efforts and that
there is a receptive community that are willing to work with
the new framework. The thesis is the first and only document
to comprehensively explain this work and show its potential
to justify the claims of Green et all and to support future
work.
Future work
events and places, FLUID, distributed discovery, ..... further
work includes work on how to discover the extra pieces - using

- Introduction
- This chapter introduces the thesis. It covers:
- scope of the thesis
- research rationale and objectives
- project history
- thesis organisation
- chapter summaries
- Context and methodology
- This chapter provides a context for the thesis and how it
was designed to work. It covers:
- Web 2.0
- relevant accessibility organisations
- relevant standards organisations
- research methodology
- Accessibility
- This chapter considers accessibility as it is understood
from a number of perspectives and ends by showing what accessibility
means to a Web user. It covers:
- understanding accessibility
- inaccessibility and how it affects people
- understanding disability
- accessibility of resources
- geospatial information
- WCAG-ATAG-UAAG
- This chapter describes the history of universal design
and shows how the technical work of accessibility has been
determined by that history. It covers:
- the early history of accessibility
- Web Content Accessibility as separation of structure
and presentation
- the WAI Requirements gathering function
- compliance and conformance
- the history of the text-only page
LitReview
This chapter provides a critical summary of relevant literature
and activities in the field from the perspective of models
and frameworks etc. It does not discuss either metadata or
accessibility more than to give a necessary understanding
of the literature. It covers:
- the drivers for Web resource accessibility
- the European perspective
- evaluation of the W3C WAI approach
- responsibility for
accessibility
- EuroAccessibility
- ISO/IEC JTC1 SC36 WG
Metadata
This chapter introduces metadata as it is understood from
a number of perspectives and ends by showing the relationship
between metadata and mapping. It covers:
- formal definition of DC metadata
- metadata for Web 2.0
- graphical representations of metadata - tags
- thesauri and ontologies
- cartographic maps and metadata maps
- accessibility metadata
- content adaptation services
Accessibility Metadata
This chapter demonstrates the availability of metadata
relating to accessibility and outlines the development
of DC accessibility metadata.
- Existing accessibility metadata
- Sources of accessible resources and their descriptions
- Dynamic Content Adaptation Services
- Early Dublin Core accessibility work
- Accessibility metadata and WCAG 2.0
User
Needs and Preferences Profiles
The matching process is initiated by the user profile so
responsibility is on the user to provide the profile - problems
when people are incapable of doing this either because of
their disability or because of ignorance. It covers:
- Inclusion means attention to user needs and preferences
- Accessibility profiles
- Mobility and Disability
- Accessible resources and services
- Relationship Descriptions
- User needs and preferences
- A user needs and preferences application profile
- User needs as a resource
- Accessibility Vocabularies
- note that this chapter should cover how the reqs
for PNPs were determined, what SWAG is doing
Resource
Accessibility Profiles
The matching process also depends on the correct and rich
descriptions of the content. responsibility is moving to
the metadata creators - not so much the content creator who
may not have succeeded in making universally accessible content
and who may not have made good metadata. It covers:
- Primary and equivalent alternative resources (or components)
- The AccessForAll metadata specifications
- Facilitating discovery of alternatives
Matching
This chapter introduces the definition of accessibility
as the matching of resources to users' needs, individually.
It also shows how the responsibility for accessibility is
moving to the server and draws a distinction between WAI
conformance and accessibility while showing their complementary
nature. It covers:
- The utility of metadata
- Access For All matching
- Discovery of resources for users with PNP profiles
- Constructing a new query
UI
Profiles
Where there are user profiles and resource profiles, the
next step is to give access to all these by having a single,
universal device that can provide the user with an interface
dynamically made suitable for the context in which it is
to be used - the URC. Responsibility is moving to hardware
developers to make their devices intelligent and capable
of speaking a common interface language. None of this works
without swappable UI components so this chapter talks about
the FLUID project. It covers:
- Interoperability
- blurb about this ..... It covers;
- Provision of Networked Accessible Resources
- Describing Control and Display Requirements for interoperability
- Describing Content Needs and Preferences and Resources
for Exchange
- The History of the AccessForAll Interoperability Efforts
- Enabling Interoperability
- The Benefits of Interoperability
Framework
This chapter looks at what is on offer and talks about
what makes a framework. It covers:
- The multidimensional framework
- The need for a framework
- The layers of abstraction
- ????
Implementation
This chapter shows that implementation is not easy - first
the model from DC 2005 then the revisions for DC 2006 and
the further FRBR problems .... also what ISO is doing, IMS
is doing, etc ....then whether all this works in a table
of georgrahic resources and their description - this last
section might not work!!! - seems irrelevant...
should include list of implementers and what they know...
Conclusion
This chapter brings it all together by showing that careful
investigation of the possibilities leads to a certain conclusion
- .....
Web
Content Development Section
This section is a large effort to interpret the general principles
outlined in the WCAG into functional pieces that can be used
as 'just-in-time' support for developers. Each section shows
how the effort has really become on of using the correct language
for the task - abstracting the work from the content creator
to the technology.
