Migrating people tags from Microsoft WLPG to Adobe Lightroom

[pybely]

I am using Phil's config file to transform People Regions from WLPG (Photo Gallery) to the MWG standard used by Lightroom ( exiftool -config convert_regions.config "-regioninfo<myregion"). Works fine.

Then I use the exiftool command  "-xmp-dc:Subject+<RegionPersonDisplayName" to assign keywords for the people names.  Works fine too.

However, I would like to put each name hierarchically under an overall PEOPLE keyword, that is to say assign to each name a keyword such as "PEOPLE/John Doe" instead of just "John Doe".

I can do it when there is only one person in the regions, using the exiftool command

           "-xmp-dc:Subject< PEOPLE/${RegionPersonDisplayName}"

However, I do not know how to do it when there are several identified persons in the photo, in which case the RegionPersonDisplayName is a list of names separated by commas (i.e. John Doe, Linda Parks, Tom Hat).

I messed around with the idea of making that command part of Phil's convert_regions.config since the people names are read in the config file, but I am not knowledgeable enough to do it.   I also tried using a structured command, but again I am not good enough for that.

Any help appreciated...

If you're willing to run it as a separate command, then you could use this:
exiftool -api "Filter=s/^/PEOPLE\//" "-xmp-dc:Subject+<RegionPersonDisplayName"

I'm not sure how the api Filter would interact with the convert_regions.config, so I wouldn't try and run them on the same command without some testing first.

Many thanks !  It works perfectly -- (I ran it as a separate command from the config file).

Hi

Sorry for coming back to you regarding the same issue but I do have a problem with the api filter command.

The command that I am using based on your recommendation:

exiftool -api "Filter=s/^/PEOPLE\//" "-xmp-dc:Subject+<RegionPersonDisplayName"  -m -r -overwrite_original  DIR/Filename

works perfectly for one single photo or a series of photos in a single folder using *.jpg as an argument, but it does not when using a Directory.  With a DIR, Exiftool is happy and indicates that photos are updated, but the Subject Tag disappears.

It looks like there is some sort of conflict between api and the recursive (-r) argument, but I am at a loss on how to fix that.

Thanks again for any help

There is a conflict with the -r option, but it's with trying to use *.jpg.  The -r option only accepts directories as targets.  If you only want to process jpegs, add -ext jpg. See -r docs and Common mistake 2 for more details.

Remove the -m option.  This suppresses the output of errors.  Something else is going wrong and you can't see what it is because you're suppressing the error output.

As long as "-xmp-dc:Subject+<RegionPersonDisplayName" is what is on your command line, then the Subject tag shouldn't be blanked.  Can you find a image where this happens that you can share and the command you use and example directory path so I can try and duplicate it?

Hi

After numerous tests, I found out that the "api Filter.... Subject+<Region..." command does not seem to work when the photos are on  a  hard disk different from the System disk.

More precisely, everything is fine when the folders/subfolders containing the photos to be changed are located in the C:\..\Pictures directory.

But it is not when   the photo folders are on a different hard disk (as they were in my case, e.g. E:\ ).  In that case the "api Filter.... Subject+<Region..." command does not operate.  Not only that, it erases whatever was in the Subject tag.

I tried running exiftool from my E:\  Hard Disk (installing exiftool there and renaming the PATH accordingly), but that did not help.  Could exiftool and the api filter rely on system stuff which is only on C:\ ?

Anyway, unless you have a ready made answer, it is not worth your time helping me with this problem any more.  I have an easy (if lengthy) work around: copying my entire collection to C:,  running the exiftool command on them and recopying the updated files onto my accessory hard disk.

Thanks again for helping me with the clever api filter !

I don't know why that would be.  When I tested the command while making it, the test file was on a different hard drive.  Actually, all the commands I run the files are all on different hard drives than my system drive, where my working directory is.

I tried running exiftool from my E:\  Hard Disk (installing exiftool there and renaming the PATH accordingly), but that did not help.  Could exiftool and the api filter rely on system stuff which is only on C:\ ?

No, something else is happening here.  As I said, every file I run exiftool on is on a drive other than my system C:\ drive and there's never a problem because of it.

Anyway, unless you have a ready made answer, it is not worth your time helping me with this problem any more.

Personally, I'd like to figure out what the problem is.  But if you're fine with your solution then I'll let it go.
