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.

2 Scope

The scope of work of this group is to gather, coordinate, and further develop tools that can help evaluate and improve web pages and sites.

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 must be evaluated, the expected duration of the ER-WG is two years, at which time the group should be re-chartered for the duration of WAI work.

4 Deliverables

5 Dependencies of other groups on this group

5.1. Groups which will use deliverables

5.2 Liaison Methods

  1. Documents and pointers to tools published on the groups web site.
  2. Meetings between chairs (WAI-CG) as needed.
  3. ER IG chair needs to sit on ER WG, and the reverse.

6 Dependencies of this group on other groups

6.1 Groups whose work will be used

  1. WAI Evaluation and Repair Interest Group (WAI-ER-IG): we will look to this group for input in the area of tools coordination, evaluation criteria, and overall production of empirical data.
  2. WAI Page Author Guidelines Working Group (WAI-GL). We will use the author guidelines as a basis for discussion.
  3. 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 deliverables described in sections 5 and 6 above.

In addition,

8.2 Relation to External Groups

9 Milestones for work items & deliverables

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:

10. Meeting mechanisms & schedules

11. Communication mechanisms

11.1 Communication within the group

11.2 Communication with W3C

11.3 Communication with the public

12 Voting mechanisms and Escalation

This group is not producing formal W3C recommendations.   The voting results will simply be indications of the personal opinions of people in the group.   Therefore, there will be one vote per member (even if there are multiple members from a particular organization).   Votes shall be submitted via email.   

Escalation of issues within ER WG or between ER WG and IG goes to the WAI Coordination Group.

13 Level of involvement of Team

14 W3C staff contact

15 Estimated time commitment a group member would have to make in order to participate

16 Participants

Participants will be drawn from the list of people writing Evaluation and Repair tools at the time of starting the working group and people with programming skills wanted to give some of their time to the group. A draft list is available.

This work will address all disabilities that potentially affect web use (listed alphabetically)

  1. cognitive (e.g. short term memory loss, learning disability, dyslexia)
  2. hearing (including deafness and hard of hearing)
  3. motor (including difficulty of fine motor control and speed limitations, e.g. keypresses/min.
  4. vision (including low vision and total blindness)

The chair of this group is Daniel Dardailler.
