I want to define a new set of tags so I can copy the metadata of one file that already has these tags to another file that doesn't have them yet.
They should appear under ---- Userdata ----
Now this is what's in my config file
%Image::ExifTool::UserDefined = (
'Image::ExifTool::XMP::Userdata' => {
ColorPalette => { },
},
);
but the program tells me it can't find the table Image::ExifTool::XMP::Userdata when I try to use the tag.
How can I accomplish what I'm trying to do?
You need to define a table with a namespace for your Userdata tags. Something like this:
%Image::ExifTool::UserDefined::Userdata = (
GROUPS => { 0 => 'XMP', 1 => 'XMP-Userdata', 2 => 'Image' },
NAMESPACE => { 'Userdata' => 'http://ns.somename.com/Userdata/1.0/' },
WRITABLE => 'string', # (default to string-type tags)
ColorPalette => { }, # (what format do you want this to be?)
);
%Image::ExifTool::UserDefined = (
'Image::ExifTool::XMP::Main' => {
Userdata => { # <-- must be the same as the NAMESPACE prefix
SubDirectory => {
TagTable => 'Image::ExifTool::UserDefined::Userdata',
},
},
},
);
There is an example of this in the example config file (https://exiftool.org/config.html).
