Dear List, Using the current version, it is now pretty straightforward to create PDFs that pass VeraPDF with PDF/UA-2.
Canvas (which is commonly used in the US) has an accessibility checker: https://community.canvaslms.com/t5/Canvas-Basics-Guide/How-do-I-use-the-Accessibility-Checker-in-the-Rich-Content/ta-p/618238 The file tagging-basic.pdf scores 40% accessibility, with three complaints: This PDF does not have headings This PDF does not have a title This PDF contains text with insufficient contrast The last item I can fix. A title can be added in Canvas. Of course, the document has all the ConTeXt headings, but apparently Canvas is not able to see them (nor the title). On the Canvas page it says about headings: • Sequential headings: Heading levels should not be skipped (e.g. H2 to H4). However, the tool does not check if the first header starts with H2 or whether the headings are sequential with the rest of the content in the page. Tables do not begin with H1, which is designated for the page title. Is there a way to make the headings visible in the PDF? Thanks, Matthias (I can help with testing and give you access to a Canvas site, if needed) ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
