I just ran CreatePDF.java from the example project with only one line
changed ("id.setPart(2);") and then successfully validated it on
https://www.pdf-online.com/osa/validate.aspx
and with VeraPDF.
The XML is:
<?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?><x:xmpmeta
xmlns:x="adobe:ns:meta/">
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";>
<rdf:Description xmlns:dc="http://purl.org/dc/elements/1.1/";
rdf:about="">
<dc:title>
<rdf:Alt>
<rdf:li xml:lang="x-default">target/test-output/PDFA.pdf</rdf:li>
</rdf:Alt>
</dc:title>
</rdf:Description>
<rdf:Description xmlns:pdfaid="http://www.aiim.org/pdfa/ns/id/";
rdf:about="">
<pdfaid:part>2</pdfaid:part>
<pdfaid:conformance>B</pdfaid:conformance>
</rdf:Description>
</rdf:RDF>
</x:xmpmeta><?xpacket end="w"?>
I see one difference in the title line. See this:

Hi,
I'm trying to create PDF/A files using PDFBox 2.0.12. My code is based on the
example code from the PDFBox repo. It creates the PDF file and I can verify XMP
data is in it containing my parameters. But tools like veraPDF and pdfPilot say
it's invalid (no PDF/A info, no metadata).
So I converted the file using pdfPilot. I extracted the xpacket XML part from
the resulting PDF file. And I added this data directly without using PDFBox
API. And the resulting PDF is valid to both apps.
So I think the way PDFBox writes XMP data to PDF files, it gets invalid. Can
someone confirm that or is there something wrong in the way I do it?
I also wrote a question on stackoverflow with further infos on this:
