How to create tagged PDF such that they will be:

  1. good enough for PDF/UA
  2. "reflowable" on smaller screens and ebook readers

Any syntax & any engine will do. Preferably using LaTeX with [Xe|pdf]latex engines.

I've heard that this isn't possible with pdftex as it is, though I think it would be a fantastic benefit. – Andrew Stacey Jul 29 '10 at 15:26

It is said that ConTeXt mkiv can create tagged pdf. See wiki.contextgarden.net/Release_Notes (and search for tagged pdf) or ask on the mailing list. – dıʞsdoʇ Feb 13 '11 at 16:19

Though tagging PDFs seems useful, I think the idea of reflowable text is a bad idea, certainly in the original context of TeX and LaTeX. The original idea was that a book designer knows best what a good layout looks like. In such an environment, the author should be able to check out the exact final appearance of the document long before it arrives on the final device. Reflowing would break that. Now I am not so much of a purist to gainsay the usefulness of reflowable text: I am reading it right now. But don't tools like web browsers and electronic books do this well enough now? – Bill Cheswick Feb 20 '12 at 17:41

@BillCheswick that's the whole poing - electronic books. I want my pdf to look stunning when printed & I want to be able to reread it on my kindle/kobo/etc with text reflowing such that I can read it normally! Also it's a question about accessibility, you want reflow tags for screen-readers. – Dima May 24 '12 at 13:06

@Bill Cheswick: The 'UA' in PDF/UA is for 'universal accessibility'. At the time you asked, it was not yet an official standard. Meanwhile it is (since a few weeks ago). – Kurt Pfeifle Jul 7 '12 at 17:46

Ross Moore talked about tagged pdf at TUG 2010:
http://river-valley.tv/tex-mathml-for-tagged-pdf-the-next-frontier-in-mathematical-typesetting/

He mentioned that he uses an "extension" of pdfTeX, but I don't know the details. There would certainly need to be a lot of work done to transform the structure of a LaTeX document into a form that a re-flowable PDF viewer could take advantage of.
