Screenshot 5 - Metadata->Exiftool not in line with rating shown in thumbnail after change
Something else that appears wired to me: When I change the star rating using the mouse in the stars at the bottom of the thumbnail - the star rating on the Metadata-Exiftools does not change.

I now went into Apple Aperture and did a âwrite Metadataâ to File - checked that the jpg file was updated. In DigiKam I reloaded the Metadata (for the file D81_9520.jpg) - no change in DigiKam. Still no star rating shown. D82_1044.jpg - also done in DxO PhotoLab - a bit newer Version. But: I have tons of other pictures also done with the same versions of DxO and there star ratings are shown correctly. Best, Tom The XMP metadata in the images are defective, yes Exiftool can read them but we use Exiv2 to write / read. Maik Tom, I recommend to report this problem to Exiv2 team from Github. Don't forget to precise the program name used to assign the stars, the operating system version, and to attach images files to reproduce the dysfunction with the Exiv2 CLI tool. https://github.com/Exiv2/exiv2/issues Best Gilles Caulier You should report the problem to Exiv2 so that it "becomes more tolerant" when it comes to decoding the XMP metadata. You can repair the metadata with the following command, but as you can see, Exiftool will also issue a warning: exiftool D81_9520.jpg -xmp:all= -tagsfromfile @ -xmp:all -overwrite_original Warning: [minor] Bad NikonScanIFD directory - D81_9520.jpg 1 image files updated Maik Exiftool can validate the metadata for correctness, here is the output for your images: exiftool -error -warning -validate -a D81_9520.jpg Warning : [minor] Bad NikonScanIFD directory Warning : [minor] Fixed incorrect URI for xmlns:MicrosoftPhoto Warning : [minor] Ignored empty rdf:Bag list for dc:subject Warning : [minor] IPTC By-line too long (36 bytes; should be 32 max) Warning : [minor] IPTC TimeCreated too short (6 bytes; should be 11) Warning : [minor] IPTC DigitalCreationTime too short (6 bytes; should be 11) Validate : 6 Warnings (all minor) exiftool -error -warning -validate -a D82_1044.jpg Warning : [minor] Non-standard IFD0 tag 0x4746 Rating Warning : [minor] Bad NikonScanIFD directory Warning : [minor] Fixed incorrect URI for xmlns:MicrosoftPhoto Warning : [minor] Ignored empty rdf:Bag list for dc:subject Warning : [minor] IPTC By-line too long (36 bytes; should be 32 max) Warning : [minor] IPTC TimeCreated too short (6 bytes; should be 11) Warning : [minor] IPTC DigitalCreationTime too short (6 bytes; should be 11) Validate : 7 Warnings (all minor) Maik (In reply to Maik Qualmann from comment #10) > Exiftool can validate the metadata for correctness, here is the output for > your images: > > exiftool -error -warning -validate -a D81_9520.jpg > Warning : [minor] Bad NikonScanIFD directory > Warning : [minor] Fixed incorrect URI for > xmlns:MicrosoftPhoto > Warning : [minor] Ignored empty rdf:Bag list for > dc:subject > Warning : [minor] IPTC By-line too long (36 bytes; > should be 32 max) > Warning : [minor] IPTC TimeCreated too short (6 > bytes; should be 11) > Warning : [minor] IPTC DigitalCreationTime too short > (6 bytes; should be 11) > Validate : 6 Warnings (all minor) > > exiftool -error -warning -validate -a D82_1044.jpg > Warning : [minor] Non-standard IFD0 tag 0x4746 Rating > Warning : [minor] Bad NikonScanIFD directory > Warning : [minor] Fixed incorrect URI for > xmlns:MicrosoftPhoto > Warning : [minor] Ignored empty rdf:Bag list for > dc:subject > Warning : [minor] IPTC By-line too long (36 bytes; > should be 32 max) > Warning : [minor] IPTC TimeCreated too short (6 > bytes; should be 11) > Warning : [minor] IPTC DigitalCreationTime too short > (6 bytes; should be 11) > Validate : 7 Warnings (all minor) > > Maik Tanks a lot Maik. I did some further investigations: After repairing the metadata with exiftools as you proposed and re-reading the metadata from the image it is shown correctly in digikam. Then I updated the star rating in Apple Aperture and wrote the change from the DB to the jpg. Again, after re-reading the metadata information, digikam is not updating the star informtion according to the changes done in aperture, whereas all other image software packages I could test on show the changed star information. I assume this might be a challenge for other people with large repositories which are currently swithching to digikam (which is an AMAZING tool!) as well. I will try to open a request with Exiv2.

I tried - see comment below to Maik. I opened a feature request with the exif2 team. https://github.com/Exiv2/exiv2/issues/2005 Well, I don't know what metadata information for rating the Apple Aperture program changes. You have to find out and make the appropriate in the digiKam setting for metadata in the advanced settings. By moving the rating tag to the beginning of the list. digiKam searches for rating tags in the order of the list. Otherwise send a changed image from Apple Aperture. Maik Since you set a rating with digiKam, digiKam's metadata entry for the rating now also exists. Since Apple Aperture does not change the digiKam metadata entry for rating, digiKam does not recognize a changed rating. Move the digiKam rating tag from the top to the bottom in the advanced metadata settings. Maik Ok, since the problem exists in the Adobe SDK, neither Exiv2 nor digiKam can do anything here. We already have bug reports with wishes to write or read metdata with Exiftool in special problem cases. I would close the bug here for the time being ... Maik Sure - I understand - please close the bug. Thanks for your help! Best, Tom |
