This thread will from now on be where I intend to ask any and all of my Metadata questions so all of the answers will be in one place.
Thanks for bearing with me.

To begin, in ExifToolGUI, there are two fields, Exif:XPTitle and Exif:XPSubject; in the Windows "Properties" dialogue, there is a Title and a Subject.

What is the significance of the XP in XPTitle and XPSubject ??

In ExifToolGUI, whatever text I enter in XPSubject shows up in Properties Subject; however, the text I enter in XPTitle does not; in fact, I have no idea where it goes; it just disappears into the outer elements.

There is a field in ExifToolGUI, Exif:ImageDescription; the text I enter here does show up as Title in Properties --- however, if I then add a Comment or IPTC:Caption, it will replace the text in Exif:ImageDescription, but will not affect Properties Title.

I am quite adept at writing Metadata and dodging most of the pitfalls; but, the behavior of the various schools of Metadata do not play well together at all and what one enters in one may write over or eliminate what has already been correctly entered somewhere else.

With all the technology of today, why does not someone fix all of this confusion once and for all --- not by creating another method to just confuse the issue further, but make the terminology make sense and mean what it says and not mess with fields one has already written via some other method ?

and programs ---, many will either clip the entered text in the saved file at about the fifth word, or erase it completely; if one does not catch this behavior and replace the corrupted data, it is lost forever.

Consider posting your questions here:
https://exiftool.org/f​orum/index.php?board=5​.0 (external link)

I feel the pool of knowledgeable respondents would be greater there.

Definitely search the EXIFTool forum.

From the EXIFTool web page on EXIF tags:

0x9c9b XPTitle int8u I​FD0 (tags 0x9c9b-0x9c9f are used by Windows Explorer; special characters in these values are converted to UTF-8 by default, or Windows Latin1 with the -L option. XPTitle is ignored by Windows Explorer if ImageDescription exists)

See:

https://exiftool.org/T​agNames/EXIF.html (external link)

Try using EXIFtool from the command line instead of the GUI, or make sure you also check to see if Windows or some application has inserted an ImageDescription tag. In the web table to which I linked, ImageDescription is part of the EXIF spec (it is underlined).

Tags which are part of the EXIF 2.32 specification have an underlined Tag Name in the HTML version of this documentation.

Thanks for this information and the links.

So far, unless I have a prewritten command to copy/paste, my head has just been a bit thick when it comes to the Command Line (and the Terminal in Linux); but, I am not going to learn how to swim by sitting on the bank.
