Exif - IPTC-IIM - XMP mapping

[gEEvEE]

Dear all,

about a decade ago, the Metadata Working Group (MWG) defined some mapping rules between overlapping fields of the Exif, IPTC-IIM and XMP photo metadata. ExifTool can list these overlapping fields, but is there also a function to check for a violation of these mapping rules? For example, to check if the "Exif:Copyright" and "XMP-dc:Rights" fields have different values and - if wanted - take the value of the dominant field and map it to the other ones?
If not, does anybody know of a script that would do this (before I start programming something myself)?

Thanks for your help! Geert

Hi Geert,

ExifTool doesn't have a feature like this.
