Best way to include data/functions from other parts of the source code revisited

[StarGeek]

Back in this post, I asked about including  %latConv and %longConv from the XMP.pm file. I tried the suggested
include Image::ExifTool::XMP;
But I may have been putting it in the wrong place

Code Select Expand

include Image::ExifTool::XMP;

# The %Image::ExifTool::UserDefined hash defines new tags to be added
# to existing tables.
%Image::ExifTool::UserDefined = (
# new XMP namespaces (eg. xxx) must be added to the Main XMP table:
'Image::ExifTool::XMP::Main' => {
# namespace definition for examples 8 to 11
video => { # <-- must be the same as the NAMESPACE prefix
SubDirectory => {
TagTable => 'Image::ExifTool::UserDefined::video',
# (see the definition of this table below)
},
},
},
);

%Image::ExifTool::UserDefined::video = (
GROUPS => { 0 => 'XMP', 1 => 'XMP-video', 2 => 'Image' },
NAMESPACE => { 'video' => 'http://www.video/' },
#PRIORITY => 0, # copy/pasted from XMP-exif, which says "not as reliable as actual EXIF tags"
WRITABLE => 'string', # (default to string-type tags)
GPSVersionID    => { Groups => { 2 => 'Location' } },
GPSLatitude     => { Groups => { 2 => 'Location' }, %Image::ExifTool::XMP::latConv },
GPSLongitude    => { Groups => { 2 => 'Location' }, %Image::ExifTool::XMP::longConv },
GPSMapDatum     => { Groups => { 2 => 'Location' } },
);
#------------------------------------------------------------------------------
1;  #end
But this returns an error

Can't locate object method "include" via package "Image::ExifTool::XMP" at C:\Programs\UnixUtils\ExifTool/testGps.config line 18.
Warning: Sorry, XMP-video:GPSLatitude doesn't exist or isn't writable

Nothing to do.
If I change include to use, it seems to work

Would use be correct or is there a different way I should use.

"use" is the correct way to import a file.
