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, lualatex, xelatex, latex+dvipdfm, and latex+dvips+Distiller.
Version 5.7 of hyperxmp is primarily a bug-fix release. As discussed on https://github.com/borisveytsman/acmart/issues/413, hyperxmp was throwing latexmk into an infinite loop. Thanks to John Collins, Nelson Posse Lago, Derek Dreyer, and the other contributors to that discussion for identifying the problem and brainstorming the solution. hyperxmp v5.7 also includes, at Moritz Heckscher's request, a minor modification to define hyxmp@DocumentID and hyxmp@InstanceID at the end of the preamble instead of at the end of the document. This enables other packages to hook into hyperxmp's UUID computations.
