Nikon continues its practice of setting Rating to 0 on its latest cameras (Z6 in my case). IM 'Preferences/Metadata 2/Ignore rating of embedded XMP record' is set to the default of 'Yes', but if I assign a Rating in IM and write it back my Ratings vanish unless I use the Exiftool command processor (ECP) to delete XMP in the NEF file.
Is this a bug or is there something else I need to do?
In reviewing my new Z6 NEF files, I see there are quite a few embedded XMP tags (see attached ECP tag dump). I used to just delete all XMP tags from my Nikon 1 NEF files
-overwrite_original
-m
-xmp=
{Files}
but I'm not sure I want to do this with my Z6 NEF images.
This setting should work. It overrides the rating extracted from the NEF during the read and merge. Do you also have XMP sidecar files for these NEF files?
Please provide a sample NEF file and XMP sidecar file for download somewhere.

Here's a link for the same NEF file for which I did the metadata dump (see original post for metadata dump): https://1drv.ms/u/s!AtlBwiIf8wQzyCh8c_qqezMnzynE
There's no XMP sidecar for this image (yet).
Here's a link to another NEF, this time with an XMP sidecar file where I believe the only change was addition of a Rating.

If the setting doesn't work, I'll need to create a special ECP command to delete just the Rating from the in-file XMP.
Hi,
I have downloaded the sample file, thanks.
- The NEF has a partial embedded XMP record with the rating=0 value.
- When I add the file to the IMatch database, it shows up with a rating of 4, this rating comes from the XMP sidecar file you have provided. OK.
- Duplicating the NEF on disk brings the copy into the database without a rating. OK.
I now set a rating of 3 for the copy of the NEF and write back.
This creates a complete and 'rich' XMP sidecar file. The rating in the sidecar file is 3, the rating in the NEF still 0. The file shows up in IMatch with rating 3 still. OK.
Which steps do you perform to make the rating set in IMatch vanish?
I use these settings under Edit > Preferences > Metadata 2:
(https://www.photools.com/community/index.php?action=dlattach;topic=8541.0;attach=20597;image)
Edit > Preferences > Metadata 2 was indeed the issue. I hadn't changed these settings for a long time, and don't remember why I chose the ones I had (see screenshot) or whether they were just defaults from long ago.
Changing to your settings and forcing a rescan of the affected images fixed this issue. Thanks!

One other somewhat off topic question: the NEF files from my Z6 show up quite small in the Viewer (no issue with thumbnails). I assume this is because my installed codecs don't yet properly handle the Z6 NEFs? WIC Diagnostics attached.
EDIT: My Z6 NEF files show up full screen in the Viewer on my desktop; second WIC diagnostics attached (IMatch_WICDiag desktop.txt). On looking at the two files, it appears that the FPV codec isn't installed on my laptop...? Not sure how that happened...
Problem now resolved!
The setting has been added when this feature has been added. As explained in the release note at that time it is off by default (to not accidentally ignoring a 'real' rating set by the user in-camera).
If the WIC codec fails (!) IMatch falls back to using the RAWLib decoder. But when the WIC returns a small image, this is not the case.
I guess that the integrated NEF codec in Windows on your Notebook can extract a small version.
Either wait until Microsoft updates the codec, Nikon again starts to ship a NEF codec for their increasing number of RAW format variants unlikely) or switch to the built-in RAW processing in IMatch under Edit > Preferences > Application, Search for RAW on that page.
At least the NIKON Z* samples I have here are processed nicely by IMatch's internal routines.
Installing the FPC codec on the laptop fixed the problem. Now both my desktop and laptop are in sync, on that issue anyway.
