The PHP Accessibility Library
QUAIL has always had a few awesome reporters available, from one that just listed all the problems, to a fully, WAVE-like WYSIWYG preview.
However, when editing HTML content, it's also useful to just view the actual code and see exactly where the problems are. As of revision 199 of QUAIL, there's a new reporter called codeHighlight which will do just that: put a span of a certain class (for test name and severity level) around every issue found in the code.
Due to a conversation I had on Gdata Issue #2004 I'm working on a You-tube caption tests which will check if a video is captioned if it is linked to or embedded on a page. This will appear in trunk shortly and will also be part of a new services layer I've been working on for integration with external linked services for accessibility checking.
In order to allow vendors to integrate QUAIL with their applications, the library will be moving from the GPL to the GNU Lesser General Public License. This should facilitate more adoption in closed-source projects while at the same time keeping our FOSS street cred.
Kevin will be giving a presentation entitled "Automated Accessibility Testing with Drupal's Accessible Content Module" to the 2010 Online CATS conference today. You can view resources, the presentation, and soon a recording with subtitles at the CATS 2010 Notes & Resources page.
Kevin has been busily working on the newest method for building a CSS model of a page accurately so that tests can be written for luminosity and contrast against styled elements on pages. Revision 144 in the Subversion repository contains an updated css.php file with a new model that gets around some weird effects of DOMNodeList when being used after XPath queries.
For a while, QUAIL has accepted a language domain as an argument; however, there was never any implementation of this at a test-level because, well, I can only speak Spanish very poorly.
However, help is on it's way for at least test search string (like the list of key words for a skip to navigation link) due to WCAG internationalization examples I can copy.
With version 0.2.4, Quail-Lib has banished all possible errors or exceptions thrown by DOMDocument, so it can handle more easily malformed HTML documents.
Using the methods described by the WCAG SVG Accessibility Features document, the latest versions of the QUAIL library will include tests for adherence to SVG accessibility standards.
Released versions greater than 0.2.1 will have these features. As of writing, the class svgContainsTitle is in version control, and a new suite of tests that apply only to tests available in QUAIL (not the Open Accessibility Checks standards) has been introduced.
Kevin has put in a proposal for the QUAIL-powered Accessible Content Drupal Module at the 2010 Drupalcon. Check out the conference proposal at the Drupalcon site.
