The accessibility of the German language Wikipedia was assessed. The assessment was carried out following WCAG 2.0 guidelines by several blind people and people with multiple disabilities. Analyzer tools were also used including WAVE, Web Developer and CCS2.0 (a tool for analysing colour contrast). In addition to this, script code analysis was also used. The results of this assessment then led to further recommendations for authors to avoid creating unsuitable pages for people with disabilities.
The principle recommendations to improve the accessibility of websites are:
Some of these problems which were identified on de.wikipedia.org had already been discussed in “Meta Wiki” and “Blind Wiki”. However this project was the first time that they had been systematically tested according to WCAG2.0 guidelines.
The test report and a simultaneously written checklist for authors were published as part of a MediaWiki Accessibility Tracking Group for the developer community. The report and checklist amongst other things show the state of implementation of the improvements. Wikimedi Germany developers in particular have applied several of these improvements.
