How would I go about viewing a .dmi's metadata? I'm using Exiv2 (a C++ image metadata library) and I haven't seen any IPTC, XMP, or Exif metadata in the .dmi file I'm using.

But, taking it a step back, is there any way I can just view the metadata inside notepad, or something of that nature?

Thanks for reading!
I've used this tool a few times to view metadata. It doesn't seem to show any of the things you listed (IPTC, XMP, or Exif), though it does give palette info and the zTXt chunk—which holds all of the state data about the icon.

If you have ImageMagick, you can do identify -verbose youriconhere.dmi to view metadata on the commandline.
