Re: [FXLA11Y] Minutes - 18 April 2023

Hi all,

I know accuracy is important but just a kindly reminder that this is the EPUB working group and we don’t need to litigate the finer technical points of PDF in our mailing list. If you need to discuss PDF please take it off-list.

Let’s stay on topic please.

Cheers,
Wendy

Leonard,

I know that Japanese users are annoyed since
most PDF readers (including those from Adobe)
read aloud the ruby line before the line containing
base characters.  I also know that at least two
companies write software for guessing the
relationship between ruby and base characters
(without using PDF ruby tags) so that they can
create reasonable DAISY textbooks, which
represents the relationship between ruby annotations
and base characters.  If PDF tags for ruby
are correctly used, these problems should
not happen.

Do most PDF documents lack PDF tags for
ruby?  Or, are developers unaware of them?
I do not know.  But when JIS X 8341-3:2016
is revised in the future, I will raise this issue
and make sure that it will strongly discourage
the use of those PDF generators which do not
create PDF tags for ruby.

Regards,
Makoto

From Adobe – Acrobat, InDesign and FrameMaker.

The PDF Association has also been working with the leading TeX providers to ensure full tagging support including Math and CJK.

I am sure there are other vendors that do it, but I can’t speak to which ones.

Leonard,

Thanks.  I did not know that.

But who embeds that tag?  Does Acrobat do so?

Makoto

That is incorrect Murata-san.

There is an entire section of ISO 32000 (the PDF standard) called “Ruby and warichu elements” (14.8.4.7.3) that discusses how to properly tag these elements in a PDF.

PDF tags do nothing about ruby.  In PDF documents,
ruby is just another line containing tiny characters.  As
a result, the accessibility of PDF documents containing
ruby is very poor.

IN the transcript, I find:


>Gregorio: PDF tags is very limited. similar experience with PDFs and FXL.

PDF tags are *much more flexible* than (X)HTML tags, because they are (a) extensible and (b) namespaced.

Gregorio – can you give some insight into your statement?
