Convert PDF to PDF / A-1

Question

I know that this is probably not strictly a programming issue (well, maybe it is so, I don’t know), but I am having serious problems trying to convert regular pdf (with hyperlinks, bookmarks, images, embedded fonts, etc.) .d ..) in PDF / A-1 format.

I get all kinds of errors when I check it with pdfaPilot.

How can I prepare a PDF file, so when I try to convert to PDF / A-1 there will be no problems. Most problems can be fixed with pdfaPilot, but apparently not all.

One of the problems I get is related to XMP metadata that is "not properly defined." That is what wat means, and I can do something to prevent it.

Another example: "Syntax problem: an array with more than 8191 elements" (I hope this is solvable)

I hope someone can help me here, as I am now in a tense place with deadlines that are killing me.

Answer 1

I have not encountered a similar problem before.

I am using the OpenOffice pdf viewer plugin with Jodconverter 2 to convert an existing PDF to PDF / A. Jodconverter is a python / java / CLI library that you can use to convert a document. It uses OpenOffice to convert documents.
