This paper presents a conceptual analysis of how the Web Content Accessibility Guidelines (WCAG) 2.0 and its accompanying documents can be used as a basis for the implementation of an automatic checking tool and the definition of a web accessibility metric. There are two major issues that need to be resolved to derive valid and reliable conclusions from the output of individual tests. First, the relationship of Sufficient Techniques and Common Failures has to be taken into account. Second, the logical combination of the techniques related to a Success Criterion must be represented in the results.
The eGovMon project has a lot of experience in specifying and implementing tools for automatic checking of web accessibility. The project is based on the belief that web accessibility evaluation is not an end in itself. Its purpose is to promote web accessibility and initiate improvements.
