The exception in PAC tool and the original doc in Writer
Created attachment 183343 [details] Screenshot at acept to export I hit some Accessibility messages, once clicking to export, see in the attached screenshot. So exporting anyway, seems adequate, producing issues at checking. With Version: 7.5.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 9cd0f4c2d25462feba0ffcbd906c199273821243 CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: es-ES (es_ES); UI: en-US Calc: CL threaded Jumbo Thanks to this article. I can find many good answers. This blog will be adored by everyone, I’m sure. Come to visit https://tinyfishing.co if you have free time. uh... i can't reproduce this, if i open the attachment https://bugs.documentfoundation.org/attachment.cgi?id=183341 i don't get any exception i have PAC 3 version 3.0.7.0 it reports a validation error about the title missing but no exception or crash dialog. Bibisected with linux-7.5 repo, indeed side effect (on the external tool) from bug 148934. Created attachment 183710 [details] Another example file, with simple hyperlinks bug 140617 is about the case of simple hyperlinks, now I can not decide with the PAC v2021 if those are fixed or not. Created attachment 183711 [details] The example file with simple hyperlinks converted to PDF with PDF/UA PAC fails on this, but https://demo.verapdf.org/ lets it pass with the result: Validation Profile: PDF/UA-1 validation profile Compliance: Passed Statistics Version: Parser: GreenField Build Date: Processing time: 00:00:00.010 Total rules in Profile: 91 Passed Checks: 393 Failed Checks: 0 I'm using LibreOffice 7.4.2.3(x64) - as of today the latest release. If you create a document with TOC and export it as PDF/UA two things fail with PAC 21.0.0 (latest as of today). 1.) TOC: for every line it fails with "Anmerkung ohne alternative Beschreibung" (annotation without description) 2.) on TOC page: "Tab-Reihenfolge einer Seite mit Anmerkungen ist nicht auf "Struktur" gesetzt" (Tab order on page with annotion is not set to "structure") I do agree, that repeating the headings text as links description seems wrong - and in case of some ARIA checking tools this is even considered as wrong for html documents. Nevertheless: I do have real life examples where setting the alternate description does make sense / would actually be helpful for users. In my case these documents are generated via API so the possibility to set the description without the Libre UI supporting it would be helpful, eq: .. xEntry.setPropertyValue ( "AlternativeText", "Big dogs! Falling on my head!" ); xEntry.setPropertyValue ( "Description", "Attention: following this link could hurt" ); VeraPDF fails with the same document like this: Specification: ISO 19005-3:2012, Clause: 6.6.2.3, Test number: 7 All properties specified in XMP form shall use either the predefined schemas defined in the XMP Specification, ISO 19005-1 or this part of ISO 19005, or any extension schemas that comply with 6.6.2.3.2.

Contacted the PAC project
So since this is perhaps not our bug (verapdf does not complain about new files), I contacted the upstream PAC project via their contact form, as seen on this image.
I'll come back when they answer.
Thank you for contacting PAC - I think this should have more "weight" than it would have if I had contacted them about this (to honest: did not came up with that idea). Anyway: there was a second part in my comment 9 - although ruling missing titles it as an error maybe a bug on PAC side there are circumstances where titles do make sense and adding this feature would be beneficiary. And I'm really curios about PAC teams's answer. This issue seems to be solved since https://git.libreoffice.org/core/+/0025190152a35e18c7847e91ad171df339657910 author Michael Stahl <michael.stahl@allotropia.de> Fri May 12 11:47:24 2023 +0200 committer Michael Stahl <michael.stahl@allotropia.de> Fri May 12 13:45:38 2023 +0200 tdf#155228 vcl: PDF export: /Tabs needs PDF name, not string *** This bug has been marked as a duplicate of bug 155228 *** oh interesting; so there *was* actually a problem with the PDF produced by LO, it was just impossible to see from the gibberish error message what the problem was. |
