NAME
    Image::ExifTool::MWG - Metadata Working Group support

SYNOPSIS
        # enable MWG Composite tags
        use Image::ExifTool::MWG;
        Image::ExifTool::MWG::Load();

        # enable MWG strict mode
        $Image::ExifTool::MWG::strict = 1;

        # disable MWG strict mode
        $Image::ExifTool::MWG::strict = 0;

DESCRIPTION
    The MWG module contains Composite tag definitions which are designed to simplify implementation
    of the Metadata Working Group guidelines. These special MWG Composite tags are enabled by
    calling the Load() method:

        use Image::ExifTool::MWG;
        Image::ExifTool::MWG::Load();

    By default, loading the MWG Composite tags enables "strict MWG conformance" unless previously
    enabled or disabled by the user. In this mode, ExifTool will generate a Warning instead of
    extracting EXIF, IPTC and XMP from non-standard locations. The strict mode may be disabled or
    enabled at any time by setting the MWG "strict" flag to 0 or 1. eg)

        $Image::ExifTool::MWG::strict = 0;

    This module also contains the MWG XMP tags which are loaded automatically by ExifTool as
    required, and are independent of the MWG Composite tags which must be loaded explicitly as
    described above.
