.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \s-1MWG\s0 module contains Composite tag definitions which are designed to
simplify implementation of the Metadata Working Group guidelines.  These
special \s-1MWG\s0 Composite tags are enabled by calling the \fILoad()\fR method:
.PP
.Vb 2
\&    use Image::ExifTool::MWG;
\&    Image::ExifTool::MWG::Load();
.Ve
.PP
By default, loading the \s-1MWG\s0 Composite tags enables \*(L"strict \s-1MWG\s0 conformance\*(R"
unless previously enabled or disabled by the user.  In this mode, ExifTool
will generate a Warning instead of extracting \s-1EXIF, IPTC\s0 and \s-1XMP\s0 from
non-standard locations.  The strict mode may be disabled or enabled at any
time by setting the \s-1MWG \s0\*(L"strict\*(R" flag to 0 or 1.  eg)
.PP
.Vb 1
\&    $Image::ExifTool::MWG::strict = 0;
.Ve
.PP
This module also contains the \s-1MWG XMP\s0 tags which are loaded automatically by
ExifTool as required, and are independent of the \s-1MWG\s0 Composite tags which
must be loaded explicitly as described above.
