1. Introduction
As presented in CSUN 2004 and 2005 Guidelines for older persons and persons with disabilities 桰nformation and communications equipment, software and services- Part 3: Web content) was published in June 2004. After the publication of Web Accessibility International Standards Research Working Group (WG2) was organized at INSTAC (Information Technology Research and Standardization Center, Japanese Standards Association) . The objective of this working group is (1) international standard harmonization with Web Content Accessibility Guidelines of W3C/WAI and other guidelines over the world especially with ISO and (2) promotion of JIS X 83413 in Japan. This presentation will report activities of this working group in 2005.
2. National promotion of JIS X 83413
In order to promote JIS X 8341-3, WG2 prepared techniques handbook working draft [J1S Tech], which is open to the public on the Web. This handbook explains specific
requirements of JIS Y 8341-3 in terms of (X)HTML and CSS techniques.
3. International standard harmonization
3. Japanese translation of WCAG 2.0
In order to harmonize Web Content Accessibility Guidelines, two members of WC2 participate
in WCAG Working Group of W3C/WAI. WC2 translated June 30 Working Draft of WCAG 2.0 [WCAC2.OWD] and some Techniques documents for WCAG 2.0, which is open to the public on the Web [WCAC2.OWD 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 83413:2004 and the current WCAG 2.0
Working Draft, WG2 compared specific requirements of JIS X 83413 and success criteria of
WCAG 2.0 Working Draft.
We found the following success criteria are not covered by JIS X 83413:
1) GL 1.2 Level 3 SC 1: Sign language interpretation is provided for multimedia.
2) CL 2.4 Level 2 SC 1: More than one way is available to locate content within a set of delivery units.
3) CL 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梤elevant 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) CL 4.1 Level 1 SC 1: SGML-based delivery units are well-formed.
7) CL 4.2 Level 1 SC 2: Content using baseline technologies or non-baseline technologies, must meet the following criteria:
A. 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
B. If the user can enter the content using the keyboard, then the user can exit the content using the keyboard.
8) CL 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
hangs dynamically in response to user input or external events.
) CL 4.2 Level Sc 5: The states and values of content that can be changed via the user
interface can also be change programs critically.
10) CL 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) CL 4.2 Level 3 S 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.
