Oh, ok, so it isn't necessarily set in stone. What do other PDFBox devs think? Is there interest in modifying XmpBox to be more lenient? Not for 2.0.0, obviously... :) -----Original Message----- From: Tilman Hausherr [mailto:[email protected]] Sent: Tuesday, March 08, 2016 12:56 PM To: [email protected] Subject: Re: roadmap for XMPBox?

It's your comment that made me realize that with XMPBox, we can't parse some files that are not PDF/A compatible but are correct XMP files. I don't have an idea what to do. Maybe improve XMPBox as you suggested (I did have a look but it doesn't seem easy). Maybe resurrect Jempbox, or use the 1.8 version.
