Checkpoint 1.9 - Wikis
If using timelines in the wiki entry, ensure they are accessible
WCAG 1.0 Priority 2
WCAG Guideline 12. Provide context and orientation information.
Timelines are an excellent tool for providing a visual presentation of events over time with a hyperlinking capability of key components of the timeline. If not constructed properly, assitive technologies such as screen readers will not be able to sensibly present these to the audience.
Requirement
All timelines in a wiki entry must be accessible.
Recommendation
Use the free EasyTimeline (infodisiac.com/Wikipedia/EasyTimeline/Introduction.htm)timeline generator to generate a wiki timeline.
