I tried this and it sort of works with a warning about IPTC, but that's an effect of the data in the TIFF.

Or perhaps my technique is simply invalid. I'll admit I'm a newbie when it comes to exiftool. Try: exiftool -tagsfromfile xmp.xml test.jp2 instead of exiftool '-xmp<=xmp.xml' test.jp2 Dave Rice avpreserve.com > --Joel > > On Mar 23, 2011, at 10:31 AM, Dave Rice wrote: > >> On Mar 23, 2011, at 10:26 AM, Dave Rice wrote: >> >>> Hi Joel, >>> >>> On Mar 23, 2011, at 9:45 AM, Richard, Joel M wrote: >>> >>>> Morning, all! >>>> >>>> I thought I'd crowdsource this question. 8+ hours of beating up on this and I haven't found a good solution. >>>> >>>> We have some software that processes the scanned pages of a book. They come to me as TIFF and I am converting to JP2 in order to upload to the Internet Archive. The trouble is that I can't find a reliable piece of code or a process to add XMP metadata to the JP2.
