The community group is format independent. So, it is good to avoid this discussion in EPUB 3 WG and use Publishing CG.

At the same time, I would recommend Leonard to compile all these accessibility features of PDF in a webpage and point the community to it. It would be very helpful for the accessibility community. If such a webpage already exists, then please point us to it.

 

Thanks

While I understand keeping the working group focus, I personally have found these type of conversations illuminating and informative (and having the depth of knowledge Leonard has available to us is invaluable!).  I believe it is good for those of us who understand (or try to!) the details of EPUB to also understand their corollary in the PDF world, especially if we bring both formats to the marketplace.

 

Perhaps a thread in the community group?

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

[EXTERNAL] This message comes from an external organization.

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

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?
