Hello ConTeXt friends,
I am newly exploring ConTeXt in search of a better way to produce
PDF/UA-1 accessible and PDF/A compliant documents programmatically. From
my early experiments, ConTeXt docs appear to fully satisfy the veraPDF
validator, but Adobe Acrobat’s Accessibility Checker has three qualms
with ConTeXt-produced documents:
1. The document is configured to display the file name rather than the
title in the top of the window (DisplayDocTitle == True is what I
think is required). See here
<https://www.w3.org/TR/WCAG20-TECHS/PDF18.html>.
Does this work at your end?
\setupinteraction
[title=MyTitle,state=start]
\setupinteractionscreen
[option={title}]
\starttext
test
\stoptext
2. "Tagged Annotations" fails, suggesting that the document’s links are
not properly tagged. I believe the issue is missing "Link - OBJR”
(object reference) tags. See here
<https://amp.levelaccess.net/public/standards/view_best_practice.php?violation_id=807>,
here <https://www.w3.org/TR/WCAG20-TECHS/PDF11.html>, and here
<http://verapdf.org>.
3. "Tab Order" fails, I believe because ConTeXt does not specify that
the tab order should follow the Document Structure, so Acrobat reads
it as unspecified. See here
<https://www.w3.org/TR/WCAG20-TECHS/PDF3.html>.
Is there something I could be doing to correct these issues in my
ConTeXt documents? Or is this a change that would have to be made within
ConTeXt itself? I know that Adobe is not the definitive arbiter of what
an “accessible” PDF looks like, but for many organizations, passing the
Acrobat accessibility checker is a prerequisite, so it seems worthwhile
to me to make ConTeXt capable of it.
Most fo this is rather trivial but we need examples (mwe) and expected
result (in only have an old acrobat x pro and the latest reader, so
maybe i can't check all the latest greatest fancy features).
