#taggedpdf — Public Fediverse posts

Yves-Marie André's (1675–1764) [https://en.wikipedia.org/wiki/Yves_Marie_André] ‘Essay on Beauty’ (‘Essai sur le beau’, 1741) was an important work of 18th-century aesthetics. In the article on beauty in the 2nd volume (1752) of the ‘Encylopédie’, Denis Diderot praised André's system as the best he knew, elevating it above the work of Plato, Augustine, Wolff, Crousaz, Shaftesbury.

In 2010, I released a #CreativeCommons-licensed annotated English translation [https://archive.org/details/EssayOnBeauty]. I have just made an update: the PDF is now an accessible #TaggedPDF.

(The LaTeX tagging system is still under development [https://latex3.github.io/tagging-project/], but I have been adapting my LaTeX styles to be tagging-compatible.)

Although I was a much less practised typographer 16 years ago, I have left the overall design of ‘Essay on Beauty’ unchanged, contenting myself with minor improvements offered by an updated version of the Baskervald font, ensuring that line-end hyphenations follow the OUP standard, and a few other localized improvements.

Der Löwe und ich machen uns startklar für die #CLT2026 (@clt_news)

Mal sehen was dieses Jahr so für Fragen am #DanteEV Stand vorbeikommen und was wir so dazu lernen. Also falls ihr zufällig gerade die eine oder andere Frage dabei habt... Wir werden versuchen zu helfen. Bei den Themen wie #TeX & Friends, insbesondere #TeXLaTeX, #eRechnung, #ZUGFeRD , #TaggedPdf ist die Wahrscheinlichkeit, relativ hoch, dass das klappt.

[1/2] Ulrike Fischer showed a summary of the #TeXLaTeX News including a preview for the next release in June.

Of course she included achievements of the tagging project which included the new template based implementation of sectioning commands.

And the status of accessible math typesetting using #MathML https://www.latex-project.org/news/2026/03/05/PDFA-press/ which is a huge step towards completely accessible documents.

The PDF Association @PDFassociation announced their "all-new" Product Showcase in January. The new interface provides an improved search, and the ability to search by product types, standards, and features.

For example, you can search for only open source or no-cost solutions. Or ones that offer Tagged PDF or PDF/UA-1 or 2. Or filter the results to only list those who offer "Remediate Tagged PDF" service.

If you are confused about your schedule, here's a summary. The PDF schedules provided by the City of Toronto and Circular Materials are both correct. Some map areas have changed their pickup schedules: for example, Parkdale used to be Wed Day 2 and they have now switched to Wed Day 1. The PDF versions of the maps show these changes correctly. But the mobile app and website lookup function don't.

Folks affected by Day switches should have received special printed mail notices about these changes, but some didn't.

One disappointing note about the PDF calendars: while those on the city's site are visually identical to those on Circular Materials site, the ones used by Circular Materials are inaccessible and untagged. Why don't they use the same tagged versions that are on the city site? Who knows! Does Circular Materials even know about the AODA (Accessibility for Ontarians with Disabilities Act)? No they don't.

@ctietze I need to be able to make slides from #OrgMode files. But #Beamer cannot (and will not) be made to produce #taggedPDF output (thanks, @mxp). So rather than bang my head against #TeXLaTeX, I took a step back.

Okay, gang, more vacation-work. Going all-in on #accessibility, and it appears I need #texlive2025 to produce semantically #taggedPDF output from #TeXLaTeΧ. I'm still on #Debian12 so here goes.

# may take several hours to run

LOL

Advice or pointers to resources welcome. Obviously the final goal is #OrgMode export in #Emacs.

Big update to the annotated edition of G.H. Hardy's ‘A Mathematician's Apology’: the PDF is now *tagged* (plus various minor improvements).

(A #TaggedPDF contains extra semantic information to assist screen-reading software etc.)

The new version is available (#OpenAccess as always) at https://archive.org/details/hardy_annotated

The LaTeX tagging system is still under development [https://latex3.github.io/tagging-project/], but I have been making progress in adapting my LaTeX styles to be tagging-compatible.

For the annotated ‘Apology’, I also had to re-implement a subset of the functionality of the "manyfoot" package (which is currently not tagging-compatible), because there are two different kinds of footnotes in the annotated ‘Apology’. (Hardy's original footnotes and the annotations.)

Although the PDF passes VeraPDF validation, there may of course be mistakes in the tagging. Feedback, especially from users of screen readers, would be much appreciated, especially because I now hope to add tags to ‘Form & Number: A History of Mathematical Beauty’ [https://archive.org/details/cain_formandnumber_ebook_large].

‘Bertrand Russell & Trinity: A college controversy of the last war’ is a pamphlet written by G.H. Hardy in 1942, giving an account of the dismissal of Russell from his Trinity College lectureship in 1916 following his criminal conviction for anti-war political activity. (Hardy was at the time a fellow of Trinity and opposed Russell's ouster.)

I have uploaded a re-typeset version of Hardy's pamphlet to the Internet Archive [https://archive.org/details/hardy_russellandtrinity].

Creating this version was an exercise for me to learn how to (start to) adapt my LaTeX styles to the new interfaces created by the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/]. (A #TaggedPDF contains supplementary information to assist screen reading software, data extraction, etc.)

Also, Hardy's work is in the public domain; there seemed to be no downloadable ebook version of this pamphlet; and I thought that it would be a useful companion to the ‘Annotated Mathematician's Apology’ [https://archive.org/details/hardy_annotated].

I have made available the #LuaLaTeX source code on #Codeberg, in case anyone is interested in how the style was created: https://codeberg.org/ajcain/hardy_russellandtrinity

@djwudi Thanks for sharing your initial thoughts. I haven't taken the new Affinity for a test drive yet, but I'm hoping that the new integration of components gave them a chance to rework the native file format and code.

Old Canva was very frustrating for PDF tagging and accessibility, despite years of work to improve it. I always figured that part of Canva's challenge came from technical debt owing to not having had accessibility in mind at the start.

Are you the kind of person who has always wondered how to tag a subtitle, or whether a Title in a PDF should be tagged as a Heading 1, or what to do with tags when a heading breaks across several lines?

Then you might want to check out the free webinar offered by the @PDFassociation on May 15.

@julientaq @spaceninja Do you happen to know how well those might support PDF/UA or WCAG 2 standards for accessible PDFs? Anything that doesn't is a non-starter for me.

iText and PrinceXML both claim to support PDF/UA.

On the WeasyPrint site, they also claim to be able to produce PDF/UA compliant files. I wonder if anyone knows of examples I might look at?

I don't see any mention of accessibility in vivliostyle or paged.js.

#PDF #PDFUA #TaggedPDF #iText #PrinceXML #WeasyPrint

The @PDFassociation includes some general notes on the differences between PDF/UA-1 and PDF/UA-2 on their website:
https://pdfa.org/iso-14289-2-pdfua-2/

#PDF #PDFUA #TaggedPDF #Accessibility

The new PDF/UA-2 (ISO 14289-2) standard for accessible PDFs is available for EUR €179 / USD $195 / CAD $265 [1].

The provisions in PDF/UA-2 are identical to those provided by "Well-Tagged PDF" (WTPDF).

So most accessibility practitioners will probably want the free WTPDF standard along with the PDF 2.0 (ISO 32000-2) standard - also free from @PDFassociation, sponsored by Adobe, Apryse and Foxit [2]
