The +metadata is 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. The current version of hyperxmp can +embed the following metadata as XMP: author, title, subject, keywords, +copyright, and license URL. hyperxmp currently embeds XMP only within +PDF documents but is compatible with pdflatex, latex+dvipdfm, and +latex+dvips+ps2pdf. + + +Installation +============ + +There's nothing special about building hyperxmp. To create +hyperxmp.sty simply run "tex hyperxmp.ins". Install hyperxmp.sty +somewhere where pdfLaTeX can find it.

The idea behind +% \acro{XMP} is that it is an \acro{XML}-based description of various +% document attributes and is embedded as uncompressed, unencoded text +% within the document it describes. By storing the metadata this way it +% is independent of the document's file format. That is, regardless of +% whether a document is of \acro{PDF}, \acrostyle{JPEG}, +% \acrostyle{HTML}, or any other type, it is trivial for a program (or +% human) to locate, extract, and---using any standard \acro{XML} +% parser---process the embedded \acro{XMP} metadata. +% +% As of this writing there are few tools that actually do process \acro{XMP}\@. +% However, it is easy to imagine future support existing in file +% browsers for displaying not only a document's filename but also its +% title, list of authors, description, and other metadata. +% +% \paragraph{This is too abstract! Give me an example.} +% Consider a \LaTeX\ document with three authors: Jack Napier, Edward +% Nigma, and Harvey Dent. The generated \acro{PDF} file will contain, among +% other information, the following stanza of \acro{XMP} code embedded within +% it: +% +% \begin{verbatim} +% +% +% Jack Napier +% Edward Nigma +% Harvey Dent +% +% +% \end{verbatim} +% +% In the preceding code, the |dc| namespace refers to the +% \href{http://purl.org/DC/}{Dublin Core schema}, a collection of +% metadata properties. The |dc:creator| property surrounds the list of +% authors. The |rdf| namespace is the +% \href{http://www.w3.org/RDF/}{Resource Description Framework}, which +% defines |rdf:Seq| as an ordered list of values. Each author is +% represented by an individual list item (|rdf:li|), making it easy for +% an \acro{XML} parser to separate the authors' names. +% +% Remember that \acro{XMP} code is stored as \emph{metadata}. It does not +% appear when viewing or printing the \acro{PDF} file. Rather, it is intended +% to make it easy for applications to identify and categorize the +% document. +% +% \paragraph{What metadata does \textsf{hyperxmp} process?} +% \pkgname{hyperxmp} knows how to embed each of the following types of +% metadata within a document: +% +% \begin{itemize} +% \item authors (|dc:creator|) +% \item copyright (|dc:rights|) +% \item date (|dc:date|) +% \item document identifier (|xapMM:DocumentID|) +% \item document instance identifier (|xapMM:InstanceID|) +% \item format (|dc:format|) +% \item keywords (|pdf:Keyword| and |dc:subject|) +% \item license \acro{URL} (|xapRights:WebStatement|) +% \item \acro{PDF}-generating tool (|pdf:Producer|) +% \item summary (|dc:description|) +% \item title (|dc:title|) +% \end{itemize} +% +% \noindent +% More types of metadata may be added in a future release. +% +% \paragraph{How does \textsf{hyperxmp} compare with the \textsf{xmpincl} +% package?} +% The short answer is that \pkgname{xmpincl} is more flexible but +% \pkgname{hyperxmp} is easier to use. With \pkgname{xmpincl}, the +% author manually constructs a file of arbitrary \acro{XMP} data and the +% package merely embeds it within the generated \acro{PDF} file. With +% \pkgname{hyperxmp}, the author specifies values for various predefined +% metadata types and the package formats those values as \acro{XMP} and embeds +% the result within the generated \acro{PDF} file. +% +% \pkgname{xmpincl} can embed \acro{XMP} only when running under pdf\LaTeX\ and +% only when in \acro{PDF}-generating mode. \pkgname{hyperxmp} additionally +% works with a few other \acro{PDF}-producing \LaTeX\ backends. +% +% \pkgname{hyperxmp} and \pkgname{xmpincl} can complement each other. +% An author may want to use \pkgname{hyperxmp} to produce a basic set of +% \acro{XMP} code, then extract the \acro{XMP} code from the \acro{PDF} file with a text +% editor, augment the \acro{XMP} code with any metadata not supported by +% \pkgname{hyperxmp}, and use \pkgname{xmpincl} to include the modified +% \acro{XMP} code in the \acro{PDF} file. +% +% \section{Usage} +% +% \pkgname{hyperxmp} provides no commands of its own. Rather, it +% processes some of the package options honored by \pkgname{hyperref}. +% To use \pkgname{hyperxmp}, merely put a |\usepackage{hyperxmp}| +% somewhere in your document's preamble. \pkgname{hyperxmp} will +% construct its \acro{XMP} data using the following \pkgname{hyperref} options: +% +% \begin{itemize} +% \item |pdfauthor|, +% \item |pdfkeywords|, +% \item |pdfproducer|, +% \item |pdfsubject|, and +% \item |pdftitle|. +% \end{itemize} +% +% \noindent +% \pkgname{hyperxmp} instructs \pkgname{hyperref} also to accept the +% following options, which have meaning only to \pkgname{hyperxmp}: +% +% \begin{itemize} +% \item |pdfcopyright| and +% \item |pdflicenseurl|. +% \end{itemize} +% +% \noindent +% |\pdfcopyright| defines the copyright text. |pdflicenseurl| defines a +% \acro{URL} that points to the document's license agreement. +% +% It's usually more convenient to provide values for those options using +% \pkgname{hyperref}'s |\hypersetup| command than on the |\usepackage| +% command line. See +% \href{ftp://tug.ctan.org/pub/tex-archive/macros/latex/contrib/hyperref/doc/manual.pdf}{the +% \pkgname{hyperref} manual} for more information. The following is a +% sample \LaTeX\ document that provides values for most of the metadata +% options that \pkgname{hyperxmp} recognizes: +% +% \begin{verbatim} +% \documentclass{article} +% \usepackage{hyperxmp} +% \usepackage{hyperref} +% \title{% +% On a heuristic viewpoint concerning the production and +% transformation of light} +% \author{Albert Einstein} +% \hypersetup{% +% pdftitle={% +% On a heuristic viewpoint concerning the production and +% transformation of light}, +% pdfauthor={Albert Einstein}, +% pdfcopyright={Copyright (C) 1905, Albert Einstein}, +% pdfsubject={photoelectric effect}, +% pdfkeywords={energy quanta, Hertz effect, quantum physics} +% } +% \begin{document} +% \maketitle +% A profound formal difference exists between the theoretical +% concepts that physicists have formed about gases and other +% ponderable bodies, and Maxwell's theory of electromagnetic +% processes in so-called empty space\dots +% \end{document} +% \end{verbatim} +% +% Compile the document to \acro{PDF} using any of the following approaches: +% +% \begin{itemize} +% \item pdf\LaTeX +% \item \LaTeX~$+$ Dvipdfm +% \item \LaTeX~$+$ Dvips~$+$ Ghostscript +% \end{itemize} +% +% The combination \LaTeX~$+$ Dvips~$+$ Adobe Acrobat Distiller +% \emph{almost} works but is hampered by a Distiller bug (at least in +% version~7.0.5) that incorrectly replaces the first author with the +% complete list of authors in the generated \acro{PDF} file. That is, +% if a document's authors are Jack Napier, Edward Nigma, and Harvey +% Dent, Distiller replaces ``Jack Napier'' with a single author named +% ``Jack Napier, Edward Nigma, Harvey Dent'' and leaves ``Edward Nigma'' +% and ``Harvey Dent'' as the second and third authors, respectively. +% Until Adobe fixes this bug, Adobe Acrobat Distiller is not recommended +% for use with \pkgname{hyperxmp}. +% +% Besides the approaches listed above, other approaches may work as well +% but have not been tested. Note that in many \TeX\ distributions +% |ps2pdf| is a convenience script that calls Ghostscript with the +% appropriate options for converting PostScript to \acro{PDF} and +% |dvipdf| is a convenience script that calls |dvips| and |ps2pdf|; both +% |ps2pdf| and |dvipdf| should be compatible with \pkgname{hyperxmp}. +% +% \bigskip +% +% The resulting \acro{PDF} file will contain an \acro{XMP} packet that +% looks something like this: +% +% \begin{verbatim} +% +% +% +% +% energy quanta, Hertz effect, +% quantum physics +% pdfeTeX-1.10b +% +% +% application/pdf +% +% +% On a heuristic viewpoint +% concerning the production and transformation of +% light +% +% +% +% +% photoelectric effect +% +% +% +% +% Copyright (C) 1905, +% Albert Einstein +% +% +% +% +% Albert Einstein +% +% +% +% +% energy quanta +% Hertz effect +% quantum physics +% +% +% +% +% 2006-04-19 +% +% +% +% +% uuid:c4188820-aef2-0a82-626ce4182b62 +% uuid:9b62b67f-d754-626c-4c959595fd75 +% +% +% +% +% \end{verbatim} +% +% \pkgname{hyperxmp} splits the |pdfauthor| and |pdfkeywords| lists at +% commas. Therefore, when specifying |pdfauthor| and |pdfkeywords|, you +% should separate items with commas. Also, omit ``|and|'' and other +% text that does not belong to any list item. The following example +% should serve as clarification: +% +% \begin{description} +% \item[Wrong:] |pdfauthor={Jack Napier, Edward Nigma, and Harvey Dent}| +% \item[Wrong:] |pdfauthor={Jack Napier; Edward Nigma; Harvey Dent}| +% \item[Right:] |pdfauthor={Jack Napier, Edward Nigma, Harvey Dent}| +% \end{description} +% +% If you desperately need to include a comma within an author or keyword +% list you can define your own comma macro as follows: +% +% \begin{verbatim} +% \bgroup +% \catcode`,=11 +% \gdef\mycomma{,} +% \egroup +% \end{verbatim} +% +% \noindent +% Thereafter, you can use |\mycomma| as a literal comma: +% +% \begin{verbatim} +% pdfauthor={Napier\mycomma\ Jack, +% Nigma\mycomma\ Edward, +% Dent\mycomma\ Harvey} +% \end{verbatim} +% +% +% \StopEventually{^^A +% \begin{thebibliography}{1} +% \bibitem{Adobe2004:PDF} +% Adobe Systems, Inc., San Jose, California. +% \newblock {\em {PDF} Reference, Fifth Edition: {A}dobe Portable Document Format +% Version~1.6}, November 2004. +% \newblock Available from +% \url{http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf}. +% +% \bibitem{Adobe2005:pdfmark} +% Adobe Systems, Inc., San Jose, California. +% \newblock {\em {A}dobe {A}crobat~7.0.5 pdfmark Reference Manual}, October~2, +% 2005. +% \newblock Available from +% \url{http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/pdf_creation_apis_and_specs/pdfmarkReference.pdf}. +% +% \bibitem{Adobe2005:XMP} +% Adobe Systems, Inc., San Jose, California. +% \newblock {\em {XMP} Specification}, June 2005. +% \newblock Available from +% \url{http://partners.adobe.com/public/developer/en/xmp/sdk/xmpspecification.pdf}. +% +% \bibitem{Downes1994:ATB15} +% Michael Downes. +% \newblock Around the bend~\#15, answers, 4th (last) installment. +% \newblock \href{news:comp.text.tex}{\texttt{comp.text.tex}} newsgroup posting, +% January~3, 1994. +% \newblock Archived by Google at +% \url{http://groups.google.com/group/comp.text.tex/msg/7da7643b9e8f3b48}. +% \end{thebibliography} +% } +% +% +% \section{Implementation} +% +% This section presents the commented \LaTeXe\ source code for +% \pkgname{hyperxmp}.
