Web authoring accessibility guidelines

The WWAAC project's Web Authoring Accessibility Guidelines encapsulate the practical experience gained from the trials in the WWAAC project. Discussions on a number of issues helped to form a basis for guideline development: whether to have one site for all or two alternative sites, the conflicting needs of users, simplicity of content, summaries of content, top loading, tagging images, navigation mechanisms, and search engines. These discussions, along with the project's user requirements and evaluation work, have led to 8 recommendations. These are proposed as success criteria, examples and strategies to be included in the W3C Web Accessibility Initiative's (WAI) draft Web Content Accessibility Guidelines (WCAG 2.0). In summary, the recommendations are as follows:

Recommendation 1: Provide a clear representational image on the site's home page.

Recommendation 2: Alt tags should provide prime information for the user, and should distinguish between salient (most prominent) and non-salient content.

Recommendation 3: Provide simple page descriptions as metadata.

Recommendation 4: Add clear in-page link such as 'Skip-to-content' near the top of the page (as some Web developers already do).

Recommendation 5: Consider the number, location and focus of links on a page.

Recommendation 6: Provide a progressive complexity for both site and page content, so that people with different abilities may be able to obtain information from the same Web site.

Recommendation 7: Use static, rather than dynamic, content for critical parts of the Web site.

Recommendation 8: Consider a change of priorities in the Web Content Accessibility Guidelines to reflect the findings of the UK's Disability Rights Commission report (2004).
