It would be good to define what "ADA compliant" means. Even though I am an accessibility specialist, I had to google the term to find out it's about accessibility. (But I work in the UK and we have different terms and laws.) Most people interested in the subject will probably not click on this thread because they don't know the term. I will rename the thread from "Is DokuWiki ADA Compliant?" to "Does DokuWiki meet any accessibility standards?".
ADA stands for "Americans with Disabilities Act
I don't know much about this particular implementation of accessibility standards, but from what I found
there is actually no definition of what "ADA compliance" means yet and it's still more or less open for interpretation of various lawyers. The act itself doesn't define it for websites but the Department of Justice is working on more specific regulations and guidance. But...
U.S. courts and the Department of Justice (DOJ) have frequently referenced the Web Content Accessibility Guidelines (WCAG) 2.0 Level AA success criteria as a standard to gauge whether websites are accessible.
(from The ADA Checklist: Website Compliance Guidelines for 2019 in Plain English
There have been new regulations in EU countries last year regarding web accessibility. Those say websites of public sector bodies must meet WCAG 2.1 AA
. It would be great if DokuWiki could meet that as a minimum as it would meet legal requirements in various countries for various situations.
So, how accessible is DokuWiki?
When I've been working on DokuWiki (from 2005 to 2015) I've always tried to ensure things are made as accessible as possible. Since then I've learned much more about accessibility, though. And a couple of less accessible things have crept in since then as well.
I still bet DokuWiki is more accessible than most wiki engines.
Does DokuWiki meet WCAG 2.1 AA?
I doubt it. Again, I think it's better than most comparable tools. But it would be good to know exactly where it fails and do an audit and then fix things.
That's not just to ensure companies who are legally required to meet accessibility regulations can use DokuWiki, it might also increase DokuWiki's use and "market value". And even if not everything gets fixed, it's still good to include what is inaccessible in an accessibility statement.
I've been thinking of doing an audit for a while but am lacking time and motivation. I wonder if a crowdfunding campaign might motivate me...
