Image::ExifTool::MWG - Metadata Working Group support
# enable MWG tags (strict mode enabled by default) use Image::ExifTool::MWG; # disable MWG strict mode $Image::ExifTool::MWG::strict = 0;
The MWG module contains tag definitions which are designed to simplify implementation of the Metadata Working Group guidelines. These special MWG composite tags are enabled simply by loading this module:
When the MWG module is loaded, "strict MWG conformance" is enabled by default. In this mode, ExifTool will generate a Warning tag instead of extracting EXIF, IPTC and XMP from non-standard locations. The strict mode may be disabled by setting the MWG "strict" flag to zero (either before or after loading the MWG module):
$Image::ExifTool::MWG::strict = 0;
