Thanks Philip

Cache Inspector

Jon: Analyzed some 26K web pages using new rule sets / identified some bugs / showed that the rules are working pretty well.

Jon: Working on improving performance on duplicate href rules (had to disable rule during testing of html unit). Will retest with new algorithm

David: What performance increase did you see w/ rules disabled

Jon: Not able to directly identify increase, but it certainly seemed to run faster when those rules were taken out

Jon: New version of Cache Inspector published - using new rules

A new version of the OAA cache inspector is available: http://code.google.com/p/oaa-accessibility-cache-inspector/downloads/list

Jon: Took 5 seconds to analyze a page compared to around a minute before

Rules discussion

Titling Rules

Jon: Titling brings up the need for two separate rule sets.

Jon: Consider naming structure of these two rule sets of "Transitional" (today's rules) and "ARIA"

Transitional would be for non-ARIA web pages

Rules in Transitional rule set would be recommended

Rules in ARIA rule set would be required

This would be a change of our current severitys of "Minimum" and "Strict"

Minimum = Transitional and Strict = ARIA

Ann: Naming convention certainly seems more clear

all agree - that this Transitional and ARIA naming convention makes more sense

Transitional would be folks / pages that have not made the jump to ARIA yet

Title_1 would be violation of both Transitional and ARIA rulesets

Title_2 would be a Recommendation for both

Title_3 would be a Recommendation for Transitional and is not included in ARIA ruleset

Title_4 would be a Recommendation for both

The 100 characters limit of Title_4 could be changed / updated if needed

Title_3 changed to: "The words in the H1 element content on the page should be a subset of the words in the content of the TITLE element "

Title_5 would be a Potential Violation for both rulesets

Jon: next requirement is 2.4.3 Focus Order

No rules written for 2.4.3 yet

/member/wiki/WCAG_2.0_Principle_2_Operable_Rules#Requirement_2.4.3_Focus_Order

David: Not sure we could develop anything to test specifically for correct focus order

If a Web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability.

/member/wiki/WCAG_2.0_Principle_2_Operable_Rules#Requirement_2.4.4_Link_Purpose_.28In_Context.29

2.4.3 Focus Order updated with rule Focus_Order_1 (Potential Violation)

Requirement 2.4.4 Link Purpose

/member/wiki/WCAG_2.0_Principle_2_Operable_Rules#Requirement_2.4.4_Link_Purpose_.28In_Context.29

1. Provide descriptive link text: Provide link text that describes the purpose of a link.

2. Identify the purpose of a link using enclosing sentence: Identify the purpose of a link using link text combined with the text of the enclosing sentence.

3. Identify the purpose of a link programmatically: Identify the purpose of a link using link text combined with programmatically determined link context.

Jon: We currently don't have any WCAG techniques for these rules

Jon: Have tested it with AT

Jon: We have implementation support and potential support w/ Voice Over

http://www.w3.org/TR/2010/NOTE-WCAG20-TECHS-20101014/ARIA1

Ann: aria-describedby is only recommended technique in IBM checklist

Jon: For now we need to stick w/ WCAG and will make this one recommended
