We present Japanese activities of JIS X 8341-3, Web Content Guidelines for older persons and persons with disabilities, in terms of national outreach and international standard harmonization.
As presented in CSUN 2004 [CSUN2004] and 2005 [CSUN2005], JIS X 8341-3 (Guidelines for older persons and persons with disabilities -Information and communications equipment, software and services- Part 3: Web content) was published in June 2004. After the publication of JIS X 8341-3, Web Accessibility International Standards Research Working Group (WG2) was organized at INSTAC (Information Technology Research and
2. National promotion of JIS X 8341-3
In order to promote JIS X 8341-3, WG2 prepared techniques handbook working draft [JIS-Tech], which is open to the public on the Web. This handbook explains specific requirements of JIS X 8341-3 in terms of (X)HTML and CSS techniques.
3. International standard harmonization
3.1 Japanese translation of WCAG 2.0
In order to harmonize Web Content Accessibility Guidelines, two members of WG2 participates in WCAG Working Group of W3C/WAI. WG2 translated June 30 Working Draft of WCAG 2.0 [WCAG2.0WD] and some Techniques documents for WCAG 2.0, which is open to the public on the Web [WCAG2.0WD Japanese translation].
3.2 Comparison between JIS X 8341-3 and WCAG 2.0 Working Draft
In order to examine the differences between JIS X 8341-3:2004 and the current WCAG 2.0 Working Draft, WG2 compared specific requirements of JIS X 8341-3 and success criteria of WCAG 2.0 Working Draft.
We found the following success criteria are not covered by JIS X 8341-3:
1) GL 1.2 Level 3 SC 1: Sign language interpretation is provided for multimedia.
2) GL 2.4 Level 2 SC 1: More than one way is available to locate content within a set of delivery units.
3) GL 2.4 Level 3 SC 1: When a page or other delivery unit is navigated sequentially, elements receive focus in an order that follows relationships and sequences in the content.
4) GL 2.5 Level 3 SC 1: Additional context-relevant assistance is available for text input.
5) GL 3.2 Level 2 SC 3: Changing the setting of any input field does not automatically cause a change of context.
6) GL 4.1 Level 1 SC 1: SGML-based delivery units are well-formed.
7) GL 4.2 Level 1 SC 2: Content using baseline technologies or non-baseline technologies, must meet the following criteria:
1. Content that violates international health and safety standards for general flash or red flash is marked in a way that the user can avoid its appearance
2. If the user can enter the content using the keyboard, then the user can exit the content using the keyboard.
8) GL 4.2 Level 1 SC 3: The role, state, and value can be programmatically determined for every user interface component of the web content that accepts input from the user or changes dynamically in response to user input or external events.
9) GL 4.2 Level 1 SC 5: The states and values of content that can be changed via the user interface can also be changed programmatically.
10) GL 4.2 Level 1 SC 6: Changes to content, structure, selection, focus, attributes, values, state, and relationships within the content can be programmatically determined.
11) GL 4.2 Level 3 SC 1: Content implemented using technologies outside of baseline follows all WCAG requirements supported by the technology.
Some success criteria are too difficult to understand their meaning and intentions.
We also found the following requirements are not covered by WCAG 2.0 Working Draft:
1) 5.5 b) Information required to understand and operate Web content shall not rely on shape and location alone.
2) Clause 6. General requirements for assurance and improvement of information accessibility
WG2 will discuss these differences with WCAG WG in order to promote international standard harmonization.
