Scott Pakin submitted an update to the
hyperxmp
package.
Version number: 5.2 2020-05-12 License type: lppl1.3c
Summary description: Embed XMP metadata within a LaTeX document
Announcement text: ----------------------------------------------------------------------
XMP (eXtensible Metadata Platform) is a mechanism proposed by Adobe for embedding document metadata within the document itself. The metadata are designed to be easy to extract, even by programs that are oblivious to the document's file format. Most of Adobe's applications store XMP metadata when saving files. Now, with the hyperxmp package, it is trivial for LaTeX document authors to store XMP metadata in their documents as well.
hyperxmp integrates seamlessly with hyperref and requires virtually no modifications to documents that already exploit hyperref's mechanisms for specifying PDF metadata. hyperxmp can embed a wide variety of metadata as XMP, including the list of authors, document title, contact information (telephone number, postal address, email address, etc.), copyright statement, keywords, natural language, and much more. hyperxmp is compatible with pdflatex, latex+dvips+ps2pdf, latex+dvipdfm, xelatex, and lualatex.
Version 5.2 of hyperxmp is a minor update. The package now supports PDF 2.0+ when writing the PDF version number to the XMP packet and provides a new option, pdfidentifier, that records a unique identifier for the document (DOI, ISBN, etc.). Thanks to Ulrike Fischer and Niklas Beisert for their suggestions regarding this version of hyperxmp.
