Re: Wrangling Photo Metadata
This screen capture shows how the drop-down menus work. This can be done for most of the fields. It saves time, and for search purposes provides consistency of terminology and spelling.

I've used Mac TextEdit to make a plaintext file for each field, which is then imported into Photo Mechanic. In Windows, I'd use something like Notepad++. With plaintext, there's no text formatting to do. It's the most basic way to create a text file on a computer.
This is the plaintext (.txt) file that I made for the Camera drop-down menu shown in the screen capture above. Doesn't get any simpler:

Re: Wrangling Photo Metadata
@PatrickMarq has provided me with a wealth of information on the catalogue system that he's devised for his photographs. It's truly impressive, and I'm considering what aspects of it I could adopt.
Meanwhile, the iteration below of my little IPTC template is close to final. Because of the drop-down menus (see post just above), most of the fields in the template can be populated with a mouse click.
I've added a "Camera's Lat/Long" field to the location fields in the upper right. By snapping an iPhone photo as part of making an analogue photo, I have the lat/long for analogue as well as digital photos and can include it in the metadata. Lat/long is also available via Maps, Compass and Siri, but simply triggering the phone's camera creates a record that can be consulted and input later.
The folks at Photo Mechanic tell me that the location fields below the Camera Lat/Long field can't be altered, presumably due to the reverse geocoding function (see post #1). "Location ID" stands for "Location Identifier", a rather technical feature that I probably won't use. If I can't delete the field, I may use it for less esoteric kinds of Location Identifiers, such as neighbourhood names and street addresses :)
This is not a money-making exercise. The "permission to use the photo" part of the template will contain terms that encourage people to use the photos.
For me, this is a significant improvement over using Capture One for metadata and search.

Re: Wrangling Photo Metadata
Between what @PatrickMarq has shown me and what I've seen of Phil Harvey's ExifTool, I'm confident that ExifTool can duplicate what's in the IPTC template above. The advantage, apart from the fact that ExifTool is free, is that it wouldn't be necessary to repurpose IPTC data fields. All of the data, including the analogue camera data, would be where an outside viewer of the data expects it to be. However, if the audience is restricted to people who use a Linux, Mac or Windows terminal, there isn't a lot of point in doing this. The question is how much of the data popular graphical interface apps, such as Lightroom and Capture One, would present to a user.
I'm inclined to find the answer to that question sometime in the next week. I don't think that it's necessary to get too deep into ExifTool. Use ExifTool to attach select data to a photograph, and see what Capture One, which I have, shows about that data. I'd also like to know how faithfully Photo Mechanic processes data that's been input via ExifTool.
Re: Wrangling Photo Metadata
Since nobody else has responded yet, I just want to jump in for a moment to thank you for launching this thread and for the information you've posted so far. I'm in the process of revisiting how I'm going to deal with this for my own work, but I'm juggling that against some other responsibilities - hope to have a bit more to say before too much longer.

Some remarks on my side:
It’s not really needed to use the command line, if you have the exif command in a file. You have always an scheduler on all the OS. This scheduler can execute the file without any user interaction.
About the display of the EXIF fields, all the fields I uses at this time are visible in Lightroom and should visible in other programs as wel these are standaard.
At the end it’s quite easy put dummy exif data in your software, export with exif data and check with exiftool where to put it.

Good point, also known as an operating system's Cron Utility. Also, the head of marketing for Photo Mechanic tells me that he uses Mac Automator, which is a Macro Utility, to input analogue data into Photo Mechanic's IPTC Template.
There's also at least one Graphical User Interface for ExifTool, but I'm happy to use Mac Terminal and I haven't tried using it. ExifToolGUI is available on GitHub for Linux, Mac and Windows.
Good to know that all of the data that Patrick is inputting with ExifTool appears in Lightroom.
Re: Wrangling Photo Metadata
When playing around with Negative Lab Pro, I found out that this plug-in writes (for me unwanted ) exif data into the tiff file.
while examening this and updating the exiftool , I saw that there are 'new' fiields that possible can be populated.
These tags belong to the ExifTool XMP-exif family 1 group.
File Source: 1 = Film Scanner
2 = Reflection Print Scanner
3 = Digital Camera
Values integer is the output !, text is the input
This I have not found yet
Film Brand -> Portra
Film Type -> Color Negative
Film Vendor -> Kodak

At this time i'n not able to put the film stuff information into the fields, but perhaps with the exiftoom forum I may able to do this.
After running older images trough exiftool it seems that the Fields come probably from Negative Lab Pro, going to shed my light there.
Keep you all informed.
Re: Wrangling Photo Metadata
After feedback from Nate at Negative Lab Pro, it's not the software that create this.
So I have done several test with Silverfast:
16bit positive scan - empty
exiftool -s /Volumes/G-DRIVE\ 4TB/FOTO\'S/_TEMP_SCANS/Schelp\ -\ TIFF16\ -\ ITPC.tif | grep Film
32bit positive HDRi scan - files are here but empty
exiftool -s /Volumes/G-DRIVE\ 4TB/FOTO\'S/_TEMP_SCANS/Schelp\ -\ TIFF32HRdri-\ ITPC.tif | grep Film
FilmSource :
FilmVendor :
FilmBrand :
FilmType :
Negafix !! - It seems That the data is coming from the Negafix
exiftool -s /Volumes/G-DRIVE\ 4TB/FOTO\'S/_TEMP_SCANS/Schelp\ -\ Negafix.tif | grep Film
FilmSource :
FilmVendor : Ilford
FilmBrand : Delta
FilmType : 100
I have now reachout to Silverfast
Re: Wrangling Photo Metadata
After spending more time looking at options than I care to admit, I've decided that upgrading from Photo Mechanic 6 to Photo Mechanic Plus will meet my metadata needs for the foreseeable future. It's the fastest, easiest way to achieve my objective. A new license for PM Plus is US$229, and my upgrade from PM 6 cost $90. Camera Bits, which makes this software, does not use the subscription model, at least not yet, and the company's history suggests it will be some time before it pushes its users for a paid upgrade. Camera Bits also does an unusually good job on support, and is an active participant in its user forum.
Photographers have used Photo Mechanic for 25 years to import photographs, separate the wheat from the chaff and apply metadata before sending their images off to a photo editor like Photoshop/Lightroom or Capture One. PM Plus, launched in October 2020, adds a database (catalogue functionality) that, for search, can replace the databases that Lightroom, via Catalogues, and Capture One, via Catalogues and Sessions, offer. From my perspective, the main function of these databases, apart from recording edits, is to facilitate finding photographs. PM 6 does a better job than my photo editor when it comes to handling the metadata that's needed for search, and I've concluded that PM Plus makes searching easier. I just find that PM is both more powerful and more user-friendly.
I should add that I've discovered in the last few days that there are a few apps that offer a graphic user interface to input and edit EXIF data. I've tried one for Mac called MetaImage, and I think that it's a solid option. No doubt there are Windows equivalents.
