hi,

i did test with exiftool, calibre, adobe reader and pdfxchange.

the strange behavior I had with tag is related with pdf x change. if I open and save a pdfxchange pdf with adobe reader, then the import in calibre is OK.

no tag problem.

did a diff between XMP metadata (extracted with exiftool) and the result is :

import ko pdf : linearized (no) and XMP Toolkit = XMP Core 4.1.1
import ok pdf : linearized (yes) and XMP Toolkit = Adobe XMP Core 5.4

by the way, solution using version in filename is not great because then metadata are no more used. So it is not a good solution

Just to be sure : add custom "http://calibre-ebook.com/xmp-namespace" metadata in the pdf could be read back by calibre during metadata ? that was your proposal but seems hard to do with a free pdf reader.
