Tom, you have misunderstood, I HAVENT LOST ONE KEYWORD because I still had my original catalogue which I moved over from the external drive to the internal drive and re-connected with my images. Not only that but it's backed up too.

The point of my above post was that *some* keywords seem to be somehow attached to the image files, while some are not. This was not due to sidecar files. It was an experiment to help answer your question in post 21, to see if the keywords came with the images or the catalogue. I still don't know the answer, some keywords definitely do, some don't.

I want to try to figure what is different about the ones that do stick.

o.O


If you select ALL your images in Lightroom then tell it to write XMP files then do a Metadata sync it will make for all your images xmp files with the keywords and image ratings and your edit data.
I used this feature on Windows as I used iMatch for my cataloguing on Windows.


JK, I don't *WANT* XMP files, I am just trying to understand why some of my NEF files (which don't have sidecar files) seem to carry some keywords with them but not other (more recently applied) keywords.

I don't mind some Photoshop created XMP files but I don't particularly want Lightroom getting in on the act too. It just makes file management that bit harder.

OK but when I initially came across xmp files on Windows I couldnt really work out why I needed them but over the last 4-5 years I have decided they are a necessary evil as I dont want my RAW files touched by any software other than in Read-only mode.

Prior to CS3 I think that editing was destructive unless you saved the JPG/NEF with a new name so it may be that you keyworded some files and this data has been embedded in the original file rather than the data being stored in a database or xmp file.

FYI:
Some trickery that I wouldnt do unless absolutely necessary.
1.  If you use PhotoMechanic to keyword nef files, It is possible to then delete the xmp files after the transfer and still have the data but no xmp files.

2.  If you use ExifTool/ExiftoolGUI to transfer gps and location data from xmp files to my nefs (after geolocating in LR) then likewise you can delete the xmp files without losing the info.

Of course I never do this but I could if I wanted to.....
