Conceptual Model

Jon: send sample code for ruleset and rule

Jon: not integrated into the tool yet, maybe until next Monday

Jon: created a branch in source code repository (SVN)

Jon: updated version of Accessibility Inspector, for example highlight elements in the graphical interface

Ann: had problems installing the new version due to Firefox/Firebug version

Jon: updated version of Accessibility Inspector contains new preference settings

Jon: any feedback to me or Prasanna

Marc: Firefox 11.0 and Firebug 1.9.1 seems to work with Accessibility Inspector 0.92

Jon: will check with Prasanna

Jon: updated to a lot more consistent look and feel of the UI (Windows/Mac)

Marc: IBM is now using Firefox ESR versions - currently Firefox ESR 10.0.3 is what has been pushed to IBM

Jon: wcag_primary_id rule evaluation results would be associated with

Jon: optional wcag_related_ids

Jon: to associate with other wcag requirements

Jon: cache_properties to create views on the data

Jon: cache_properties as kind of filter on the data

Jon: language: if empty string --> applies to all languages

Jon: or list of languages

Jon: Rule NLS example: Natural language support

Jon: example manual test for alternative text --> long message for describing the test

Jon: messages now much shorter

Jon: placeholder % == SHOULD or MUST

Jon: same for SUMMARY property

Jon: conceptual change from "what went wrong" to "what needs to be done"

Jon: --> ACTION

Jon: should we process the widget even if it is hidden from assistive technology

Marc: widget is only not visible at the moment or in general?

Jon: at the moment

Marc: then it should be processed / tested

Jon: maybe it is junk code that never gets visible

Rich: should not test hidden content for accessibility

Rich: display = none or HTML5 hidden

Jon: maybe a setting turn on/off processing/testing of hidden widgets

Jon: TARGET property describes the elements for which the rule applies

Jon: PURPOSE property list of strings, provide developers information about accessibility

Jon: TECHNIQUES property provides more details on what to do

Jon: RESOURCES property points to the WCAG techniques

Jon: Ruleset Example

Jon: "rules" property a list of rules

Jon: each rule associated with "name", "type" and status property "enabled"

Jon: might be another participant joining the group

Jon: interested in working on the rules

Jon: I will update all code to use this new code

Widget Rules

Jon: /member/wiki/WCAG_2.0_Principle_4_Robust_Rules#Requirement_4.1.2_Name.2C_Role.2C_Value

Jon: last week started discussing ARIA rules

Jon: WIDGET_1 must have 1.) labels or 2.) names?

Marc: would prefer 1.)

Philip: what would be a "label", something shown on the screen?

Jon: yes, similar to labels used in forms

Rich: for example checkbox, the text would be the label?

Jon: yes

Jon: would prefer 1.)

Jon: use 1.) for now

Ann: what about label/name?

Jon: think it is important to be concise

Ann: WCAG 2 says "name"

Rich: "name" is what is computed

Ann: for example 4.1.2

Jon: ok, then we will use 2.)

Ann: doesn't "title" only gives a tooltip?

Jon: "title" is kind of backup

Jon: for computing the name

Jon: is "title" used much in IBM tools?

Ann: I think not

Marc: agrees


Jon: ARIA properties and states must have valid values

Ann: what about changing the ACTION to "use value according to specification"?

Jon: ok
