Hello all

First of all I must say that I am a complete newbie to the TeX world. 

I am evaluating Context for generation of PDFs for educational use. We
aim to produce PDFs that are accessible to screen reader users and for
that reason we would like to create tagged PDFs. My initial experiments
with tagged PDF have so far been unsuccessful. 

I am using ConTeXT standalone,  (ConTeXT ver: 2012.07.07 MKIV
fmt:2012.7.8 int: english/english ).

 

I am using this tex file as a test input (have left in line breaks in
case that is significant):

 

\setupstructure[state=start]

 

\starttext

\startbodymatter

 

\startchapter[title=Chapter 1]

The quick brown fox jumped over the lazy dog.

\stopchapter

 

\startchapter[title=Chapter 2]

Now is the time for all good people to come to the aid of the party.

\stopchapter

 

\stopbodymatter

\stoptext

 

When I open the resulting PDF in Adobe Acrobat 10.0.3 and show the tags
navigation pane, it says "No tags available". Can anyone suggest what I
am doing wrong? 

 

Paul Wray

I would also like to see tagged PDFs because I use Indic scripts which
have a non-linear character-glyph correspondence, so without tags PDF
content is not copy-pastable to other applications. I would also like
to be able to enable tagged PDF production where the underlying
character sequences is embedded in the PDF. I understand this will
increase the PDF size and it is not an issue for me, but being able to
copy-paste is.

Thanks!

Thanks, that works now. 
I will also need to emit accessible alternate text for images, but this
is not a tag in its own right, it appears to be an attribute of the
<figure> tag. Is this possible?

Tagging is part of PDF/A, but the interface is the same.

"pdf/a-1a:2005" and "pdf/a-1b:2005" are the used 'format' names for
PDF/A. Never used it myself, so I can't tell much about it.

Hi everyone,

in my quest to generate tagged pdf's that meet nowaday's accessibility
requirements (it seems to me that tags are the major hurdle when using
tex), I came around context.

There is a very interesting article on how to generate tagged pdf's with
context mkiv.
http://www.tug.org/TUGboat/tb31-3/tb99hagen.pdf

A quick sample run of the examples shown in the above pdf with context
however doesn't yield a nice result. Checking with the pdf accessibility
checker
http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html
for example, the generated pdf fails completely and is not considered to be
tagged.

Could someone point me in the right direction? Is there any kind of
tutorial or minimal example from where I could work on? Are there any
(hidden) options that need to be set in order to activate tagging support?

kind regards

Okay, thanks. I first need to 'finish' my e-book. But it is good to know
that I can create tagged PDF documents. (Handy for PDA's and the like.) I
see that I really need to upgrade to MKIV. Let's put a higher priority on
that. ;-}

Yes but you need mkiv.

You need \setupstructure[state=start] at the begin to enable it. It’s also important to use the start/stop commands (e.g. \startchapter) for headings.

no as i don't need it and it's not something you implement for fun 
(only as part of a project) .. it's quite doable (unrelated to luatex 
i think) but boring

Hi Hans,

these wise words were written 1 1/2 years ago ...  and publishers indeed more and more often ask for that!

For me, the only way to do tagging is with AcrobatPro. 

But as LuaTeX made so much progress in the last 18 month, maybe is there also some break-through on this topic?
