It is a format based on XML that Adobe developed for embedding metadata information in image files. This module contains the definitions required by Image::ExifTool to read XMP information. =head1 AUTHOR Copyright 2003-2016, Phil Harvey (phil at owl.phy.queensu.ca) This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. =head1 REFERENCES =over 4 =item L =item L =item L =back =head1 SEE ALSO L, L =cut
