I'd prefer to continue using your xmp parser, but I understand if you need =
to limit what you're willing to take on.

I'll take a look at xmlgraphics, and I'll discuss the fallback option with =
Tika devs about moving jempbox into Tika.

Thank you.

Cheers,

xmpbox is targeted around PDF/A-1. So I'd think we should discuss to extend=
 it to support other PDF standard meta data requirements as well as generic=
 XMP use cases to again have a generic XMP library. OTOH there is org.apach=
e.xmlgraphics.xmp

WDYT?
