Description Dieter 2019-06-06 19:39:29 UTC 
LO 6.3 provides PDF-export to PDF/A-2. That's great. Next step would be to implement PDF/A-3. I want to propose this.

Part 3 of the standard, published on October 15, 2012,[4] differs from PDF/A-2 in only one regard: it allows embedding of arbitrary file formats (such as XML, CSV, CAD, word-processing documents, spreadsheet documents, and others) into PDF/A conforming documents.


Adding cc to Thorsten, he added support for PDF/A-2 export

Moving to NEW. I think it makes sense as an enhancement
Comment 3 Jan-Marek Glogowski 2020-09-17 00:12:02 UTC 
This was merged in https://gerrit.libreoffice.org/c/core/+/84687. But that is just an additional entry to the combo box, as every PDF/A-2 is also a PDF/A-3

Now the question is, what LO should do additionally?

In theory LO's hybrid PDFs could be more PDF/A-3 compliant. Interestingly you can already select PDF/A + hybrid PDF, but that is invisible in a PDF viewer.

I can imagine embedding additional data via UNO would make some sense, not sure about GUI stuff.

Isn't PDF/A-3 already implemented? At least LibreOffice 7.3 seems to support the export to PDF/A-3 (you can select it in the export dialog).

You're right, but after reading comment 2 it "is just an additional entry to the combo box". So I think some more input is needed from a developer who is famliar with pDf-specifications.
