Hi,

In your  "after" file the existing metadata is lost. From what I see, the example creates metadata from scratch instead of changing the existing one.

What might work is something like

PDMetadata meta = catalog.getMetadata();
DomXmpParser xmpParser = new DomXmpParser();
XMPMetadata metadata = xmpParser.parse(meta.createInputStream());

(I took this from the ExtractMetadata example)

then use this "metadata" object. Please try that and tell whether that works. If not, please do again share the "after" file.

Please do also give feedback if this works. I'm thinking of adding a comment in the example.

Hi all,

I've just checked the AddMetadataFromDocInfo example from pdfbox
repository (see
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/AddMetadataFromDocInfo.java?revision=1792647&view=markup).

I've created a PDF/A-3 document with LibreOffice. Then I've used that
PDF as input for the example program. The resulting document contains
the changed metadata, but it's not a PDF/A-3 anymore. What can I do to
leave the document as PDF/A-3?

Thanks in advance,
Ralf.
