Question: The 'Subject' field found in windows image properties/details. Is there an associated field in any namespace?
You can check the table I made in the Windows metadata thread (https://exiftool.org/forum/index.php?topic=6591.msg32875#msg32875). As you can see, each Windows property corresponds with multiple tags. In the case of "Subject", Windows reads and writes only the
XPSubject tag. This tag, as well as the other Microsoft XP* tags (
XPTitle,
XPComment,
XPKeywords, etc)
that is rarely used by any program other than Windows.
Quotesometimes the 'Description' (field number 120)shows up there and sometimes the 'title' (field 05) show up there
In this case, Windows is writing the
XMP:Description/
IPTC:Caption-Abstract, though I don't have a "Description" field in my Windows->Properties window. Setting "Title" in that windows adds to these tags (and some others). The Title field 05 you mention is an IPTC IIM/Legacy tag,
ObjectName (which corresponds to the
XMP:Title tag, see IPTC Photo Metadata Standard->Title (https://www.iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#title)). I've never seen my install of Win10 set that tag.
The reason that Windows sometimes writes the tag to the IPTC IIM group is because Windows will not create a new IPTC group in a file, but will update tags there if it already exists.
