1 Mission statement
This group will produce a WAI Evaluation and Repair "toolkit" that
will be offered to people who create and maintain web sites, and
people experiencing difficulties while using the Web. The toolkit
will contain stand-alone tools as well as modules that can be
incorporated into other web authoring tools.
The scope of work of this group is to gather, coordinate, and
further develop tools that can help evaluate and improve web pages and
It is also to ensure a level of consistency, quality, and fitness
of these tools in one toolkit deliverable.
It is further refined by the goals and the scope of
functionalities of the various Evaluation and Repair tools that will
be dealt with this group.
In the area of Evaluation, we will find tools that generate a
simple notification of missing resource, as well as tools
that generate more complex reports, for one page or a complete site.
In the area of Repair, tools can specialize in one area of
accessibility (like description of image or linearization of
2-dimensional layout, like table or frame based layout) or more
generic repair tools (like changing transitional HTML into strict + style).
Both fully automated and semi-automated (involving human judgement)
tools are in the scope of the ER WG. Services located at third party
sites to provide temporary repair via a filtering or transformation
facility are also included.
The definition of accessibility rating scale is
in the scope of the ER IG group, but the ER WG will provide
input on feasibility.
2.2 Criteria for success
The main criteria for success of ER-WG is the timely deliverance and
use of tools by their intended audience (the "use" part is a joint
responsibility of this group and the Education and Outreach group)
This criteria shall be measured by the ER-IG.
3 Duration of work items
In view of the constant stream of new technology whose accessibility
be evaluated, the expected duration of the ER-WG is two years, at which
the group should be re-chartered for the duration of WAI work.
- list of all available evaluation & repair tools, with assessment of their
function, info on programming, whether they reflect WAI page author
- draft architecture of composite toolkit of E & R utilities, with list of
auxiliary utilities & plug-in modules
- utilities & plug-in modules
5 Dependencies of other groups on this
5.1. Groups which will use deliverables
Any results we obtain with implications for authoring tools
user agents will be offered to the respective groups (WAI-AU
Evaluation tools will be available to the Education and
Group (WAI-EO) to help that group's outreach efforts.
- The ER IG will have to take the
ER WG's deliverables and evaluate them, to complete its task.
5.2 Liaison Methods
Documents and pointers to tools published on the groups web site.
Meetings between chairs (WAI-CG) as needed.
- ER IG chair needs to sit on ER WG, and the reverse.
6 Dependencies of this group on other
6.1 Groups whose work will be used
WAI Evaluation and Repair Interest Group (WAI-ER-IG): we will look
group for input in the area of tools coordination, evaluation
criteria, and overall production of empirical data.
WAI Page Author Guidelines Working Group (WAI-GL). We will
use the author guidelines as a basis for discussion.
WAI User Agent Guidelines and Authoring Tool Working Group (WAI-UA
and AU) to understand how the integration of tools with User
Agents and Authoring environment is best achieved.
6.2 Required time of delivery.
The Page Author Guidelines have made sufficient progress for this
group to begin working.
In addition, several tools already exist so we can expect a first
version of the toolkit to be available by the end of 1998.
7 Intended degree of Confidentiality
Group home page, proceedings, deliverables, and charter will all be public.
8 Relation to other groups
8.1 Relation to W3C Groups
This group is related to other W3C groups via the dependencies on
described in sections 5 and 6 above.
This group is related to the people in W3C producing the
HTML and CSS validation service, and other various reporting
tools done by W3C staff.
8.2 Relation to External Groups
We will solicit input and participation from the authors of the
existing Evaluation and Repair tools
The ER WG will coordinate closely with
research institutions involved in E & R tools development, including the
Trace Research and Development Center at the University of Wisconsin,
9 Milestones for work items &
The times at which the deliverables will be produced will depend on the
advance in various tools at the time we start working on them, and the
resources available to do the work.
A tentative agenda is:
- July 98 - resource listing of all available repair
& evaluation tools, plus assessment of their
function, & info on their programming base, & whether
they are updated to WAI page author guidelines draft, etc.
- August 98 - draft outline of features, functions, and
architecture of primary toolkit, plus planned
auxiliary utilities, plug-in modules, etc.
- October 98 - Betas of a several modules (captioning,
- November 98 - Betas of more modules
- December 98 - Beta of toolkit
- January 99 - First working draft of toolkit
10. Meeting mechanisms & schedules
primary meeting mechanism:
bi-weekly meeting: by phone
quarterly (roughly) meeting: face-to-face
11. Communication mechanisms
11.1 Communication within the group
/WAI/ER/WG group home page
bi-weekly phone meetings
quarterly face-to-face meetings
11.2 Communication with W3C
coordination through WAI Coordination Group to other WAI working
communication to W3C Member organizations through WAI monthly
11.3 Communication with the public
Through monthly bulletin, public home page.
12 Voting mechanisms and Escalation
This group is not producing formal W3C recommendations. The
results will simply be indications of the personal opinions of people
the group. Therefore, there will be one vote per member (even if
are multiple members from a particular organization). Votes
be submitted via email.
Escalation of issues within ER WG or between ER WG and IG goes to
the WAI Coordination Group.
