This is great. Thanks for sharing. I was working with kMD attributes years ago before I knew much about command line. Was stuck trying to work in AppleScript (and at the time didn't really understand what Spotlight or kMDs were about), gave up, and never revisited. Really helpful to re-discover.
Just for clarity: kMD metadata is not contained in the file. It's external data, handled by MacOS's Spotlight system, which is why it won't necessarily port and can disappear or change when the file is copied or moved to another location. RE "Since my system has no known Uniform Type Identifier associated with the htaccess file extension, a dynamic type identifier is used (the dyn domain)" -- What's the story there? Is that something you imposed? I don't see have no kMDItemContentType / kMDItemTypeTree for .htaccess files on my system. Apparently you can push your own custom types into your system -- thought I'm not yet sure to what end. All very interesting.
