Adobe spends a lot of effort on duplicating this provide in different places.

about incompatible tags. Do you know why there is this discrepancy?

It supports TIFFTAG_PHOTOSHOP and TIFFTAG_RICHTIFFIPTC but only uses TIFFTAG_RICHTIFFIPTC if TIFFTAG_PHOTOSHOP is not defined, so it seems that it never really uses TIFFTAG_RICHTIFFIPTC at all.

Oh, I see. I get the warning when I call TIFFOpen, but I guess you are suppressing the warning.

If the XMP data duplicates the IPTC data, then I really don't need to worry about it.
