Property "Title" in Pictures folder/library: more than one tag read?

On various pictures, I've seen it read the XMP "Title" tag, the EXIF "Description" or "User Comment" tag, the IPTC "Caption" tag, even Keywords or Sub-categories.

So my question is, what's the limit to it all? I would think that "Title" would only display a metadata tag with a similar name, like XMP DublinCore Title, or, if it could only find its IPTC counterpart in a file, Fixture Identifier. I suppose that when you don't give yourselves all that much space to work with, as is the case with the bottom panel of a Windows 7 Explorer window, doubling- and tripling-up like this can be considered practical. Maybe I haven't looked far & wide enough, or perused the Help Center with an open enough mind as yet. All the same, I think that a tooltip or some easily-gotten-at description of the fields in that bottom 3/5 of the window would be more than enough to satisfy one's curiosity.

I won't add mischief to misery and ask "Why was this done?" as I've already partly come up with a reasonable answer myself (available space within the bounds of the window). I'll just ask if anyone else has been curious about this, and if so, invite them to comment here on this thread.

It gets worse.

Across the board, there's little to no consistency in what gets read and what gets ignored. Or so I've noticed lately.

It turns out you can change the details of the "Date taken:" field without editing that text block directly in Windows Explorer. What I find curious is that both XMP and EXIF date tags or labels are ignored, and Windows 7 only recognizes the IPTC tags "Date Created" and "Time Created." It's one of the few IPTC tags that is persistently read; the other one is, not ironically I suppose, "Tags" (IPTC Keywords).

Where I find myself pulling my hair out, again, is with the Title field. Lately I haven't seen Keywords or Supplemental Categories showing up in this field. All the same, I'm baffled when EXIF Image Description (ASCII data) gets ignored in favor of XMP Dublin Core description data (ostensibly binary data), and vice-versa. And it seems you cant predict from file to file which it's going to be.

Does Microsoft explain their reasoning behind adding these fields to the Explorer window layout in Windows7 anywhere? Taken all in all, it's hardly any better than what they gave us in Windows XP.

I'm also surprised that there haven't been any replies made to my posts on this thread.
