Hi Boris and Ross

Boris: Thank you for this. I suggest that you also make an announcement to the Blind Math list, and ask them to peer review Ross's plan of work.

Ross: I'm concerned that you're not sharing with us the source for the tagged PDFs you put up on your web site. Is it your intention that the software you produce be released under an open source license, and will be developed openly? If so, then making what you've done publicly already would be a very good first step.

Do you mean the LaTeX document source, that an author might produce?
For the journal examples, this is what you already have in a TeXLive distribution for the corresponding journal class files.

Of course there are some slight modifications
 a.  to load my extra coding — currently some 15,000+ lines of coding, unstable and undergoing constant changes and additions;
 b.  inclusion of some macro-usages, corresponding to where page-breaks occur.

I could post those document sources, but for what purpose?
Without the extra coding, you wouldn't be able to use them.

But you want that 15,000+ lines of coding too, no doubt.
Sorry, it would be quite wrong to release this at this stage.

Producing tagging PDF is not just about adding a package.
It is establishing a whole different paradigm for LaTeX document creation and validation.
There are many things that an author must do differently to current authoring practice.
I'm trying to keep this to a minimum; but it's certainly not zero.

Read my plan document.
This refers to the kinds of things that need to be done:
e.g.,  use of XMP metadata,  preprocessing images,  checking validation,
         adding alternative text for some environments and content type,
         understanding what things might be wrong when validation fails in various ways, etc.

Validation requires use of extra software that is not available as Open Source.
There are some online sites that do some of what is needed, but not all.

Both: Please note that the page contains a link to https://www.maths.mq.edu.au/~ross/TaggedPDF/, which shows up for me in Chrome as a page that is not secure. The page http://www.maths.mq.edu.au/~ross/TaggedPDF/ has no such problem. (Note the use of http, not https.)

This is just the browser being overly picky.
it is the same page, whether you use  http  or  https.
Using  https is probably wrong technically, so we should change it.

with best regards

I've added the new materials from Ross (under the "current work"
section) to https://tug.org/twg/accessibility/<https://protect-au.mimecast.com/s/6QKjCjZ12RfzBD3cWrjRy?domain=tug.org>:  the plan of work and
examples of tagged pdf produced.

Good luck


Hope this helps.
