[...] I will report back as soon as I have found out what may not be working here. After some testing, it seems we have two main issues with PDF/A-3a validations.
First, PDF/A-2 and PDF/A-3 both require "/MarkInfo << /Marked true >>", the same way as PDF/A-1 does.
https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... is just for reference.
lpdf-tag.lmt contains on line 590:
if version == 1 then
pdf version
It isn’t clear to me whether "version" here refers to PDF/A version. If that were the case, /MarkInfo is a requirement for all versions prior to PDF/A-4 (according to https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Part-4-rule...).
hm, peter checked all that against the 1.7 standard so i'm reluctant to change that; not all documents have to be marked
Second, /Namespace, /NS and /RoleMapNS are only allowed in PDF-2.0 (https://github.com/pdf-association/arlington-pdf-model/blob/master/tsv/lates...).
Since we have PDF/A-3a (and not PDF/A-4F [at least, yet]), I’m afraid the dictionary has to be /StructTreeRoot here.
There is a third issue, PDF-1.7 doesn’t allow /DocummentFragment as standard structure type. Only Part, Art (article), Sect (section) or Div would match here (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008....).
Hans, I’m afraid this is the way to go. If my writting isn’t clear, let me know.
not sure what you mean: you either tag version 1 or you tag version 2; order matters so don't enable tagging for 2 and then choose some version 1 related format (maybe i can check someplace if users mix up) but we tested and got validated documents from vera .. unless of course the standard changed again (vera also changes and there are also differences between the used parsers) it's not something i want to waste time on continuously ... just an occasional catch up with changes .. really it's not the complication but the mess that determines pace here Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
