Got it. Thank you. I wanted to confirm that nothing had changed since last
summer (PDFBOX-2855).
Are you taking bug reports for jempbox or is that entirely eol'd?
Any recommendations for a somewhat lenient, Apache license-compatible XMP
parser?
Might it make sense to include in the README or in the package javadocs
something about the goals for XmpBox? It is entirely possible that I missed
the warning. ;)
Thank you, again.
Best,
Tim

Subject: Re: roadmap for XMPBox?
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...
