w3c

There also quite some tools to test a particular website's accessibility. W3C provides respectively the following list https://www.w3.org/WAI/ER/tools/ and some explanations https://www.w3.org/wiki/Accessibility_testing . Sorry if a bit off-topic :)

evaluate the accessibility of a website

depending on the target audience of your website you may also consider to make it as accessible as possible. there exit some standards from the w3c dealing with this issue (web accessibility initiative):

http://www.w3.org/WAI

unfortunately it is not really possible to automatically test the complete accessibility as defined in the wai standards.

How to visualize an ontology

Finding a tool to visualize an ontology's structure is what this challenge is all about. It should be as simple and intuitive as possible, and, if possible, free of charge. It should be able to handle at least one of the standard ontology standards (e.g. OWL).

Validate html code

To be certain of a good representation of a homepage in different common browsers, it is necessary to validate the code.

Improve accessibility of a website

For differently-abled people it is quite complicated to access content on the Internet. To improve this the W3C consortium issued a recommendation called WCAG - Web Content Accessibility Guidelines. The <a href="http://www.w3.org/TR/WCAG10/">recommendation </a> defines 3 priority levels of the recommendations: [Priority 1] A Web content developer must satisfy this checkpoint. Otherwise, one or more groups will find it impossible to access information in the document. Satisfying this checkpoint is a basic requirement for some groups to be able to use Web documents. [Priority 2] A Web content developer should satisfy this checkpoint. Otherwise, one or more groups will find it difficult to access information in the document. Satisfying this checkpoint will remove significant barriers to accessing Web documents. [Priority 3] A Web content developer may address this checkpoint. Otherwise, one or more groups will find it somewhat difficult to access information in the document. Satisfying this checkpoint will improve access to Web documents. However a lot of websites does not fulfill even the Priority 1 recommendations. We want to find a client-side solution for altering of such pages for the people with special needs.

How to make sure your website is conform to common guidelines.

Are there automatic approaches or does this have to be checked manually? </span></span></span></span></p>
