I think the problem is that XmpBox was written for PDF/A checking, so it
fails with XMPs that are not PDF/A. For example, file 000142.pdf has the
schema http://ns.adobe.com/pdfx/1.3/ which is not allowed for PDF/A:
http://www.pdfa.org/wp-content/uploads/2011/08/tn0008_predefined_xmp_properties_in_pdfa-1_2008-03-20.pdf
And no, there are no plans for anything on XMP at this time...

All,
When we migrate to PDFBox 2.x over on Tika, I'd much prefer to switch from
our current reliance on jempbox to XMPBox. I recently extracted ~70k XMPs from
PDFs with PDFBox 2.0.0-SNAPSHOT, and when I ran XMPBox's parser, there were
exceptions on roughly 40% of the XMPs.
I’m including a table below of the counts of exception messages. Are there
any plans to make XMPBox more lenient or is this what we can expect going
forward?
As always, I’m more than happy to help with files and tests. Let me know
what I can do.
Cheers,
Tim
