See https://www.latex-project.org/publications/indexbytopic/pdf/ for articles and other material about the "LaTeX Tagged PDF" project.
This tagging-project repository does not contain any code.
It is meant to track issues and suggestions related to the "LaTeX Tagged PDF" project. The code for this project is split over several other repositories (latex2e, latex3, tagpdf, ... to name a few) and so this here is a convenient place to keep any more general topics or issues that cut across the different repositories in a single place.
If an issue that is recorded here requires changes in the other repositories sub-issues can then be opened (by us) in those repositories and linked back, or, if such changes are confined to a single repository, the issue could be transferred there – whatever is more appropriate.
Example documents conforming to both Well-Tagged PDF (WTPDF) and PDF/UA-2 standard produced by the LaTeX Project
Under "Discussions" there is a page with WTPDF / PDF/UA-2 example documents that were originally produced in March 2024 using the then current prototype code, and have been updated periodically as the code has developed. Check them out.
PDF 1.7 versions of the documents (also generated automatically by altering the \DocumentMetadata declaration) are now also available, see the page PDF/UA-1 Examples by the LaTeX Project for details.
We have written a few guidelines explaining how to use LaTeX to generate accessible PDFs. The documentation will be updated as new features become available.
At the moment other documentation about tagging is sprinkled across different places. Here is an overview on where to find these places. Eventually, this will be combined into a single document.
