In case you want to add another proprietary app xmp metadata field to the zoo:
The (rather popupular and good) Android app "F-Stop" uses the standard rating 1-5, plus a "heart" icon that maps to a custom xmp tag.
The xmp metadata sadly isn't specified anywhere (https://www.fstopapp.com/metadata/), the web page inside the xmp (http://www.fstopapp.com/xmp/) leads nowhere. I'm attaching an xmp sidcar file that is written with F-Stop's rating/favorite system.
No worries, I've covered it with a custom exiftool cfg, so I'm just mentioning it here.
%Image::ExifTool::UserDefined = (
'Image::ExifTool::XMP::Main' => {
fstop => {
SubDirectory => {
TagTable => 'Image::ExifTool::UserDefined::fstop',
},
},
},
);
%Image::ExifTool::UserDefined::fstop = (
GROUPS => { 0 => 'XMP', 1 => 'XMP-fstop', 2 => 'F-Stop' },
NAMESPACE => { 'fstop' => 'http://www.fstopapp.com/xmp/' },
WRITABLE => 'string', # (default to string-type tags)
favorite => { Writable => 'favorite' },
);

Um, attaching the xmp file didn't work, here's the content:
<?xpacket begin="�" id="W5M0MpCehiHzreSzNTczkc9d"?>
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="XMP Core 4.4.0-Exiv2">
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<rdf:Description rdf:about=""
xmlns:xmp="http://ns.adobe.com/xap/1.0/"
xmlns:fstop="http://www.fstopapp.com/xmp/"
xmp:Rating="1"
fstop:favorite="1"/>
</rdf:RDF>
</x:xmpmeta>
<?xpacket end="w"?>
Thanks for the suggestion. I'll keep this in mind.
