+\section{Introduction}
+
+This package provides some basic functionality
+to store and compose strings.
+The main goal is to keep relevant information
+for the document in a structured way
+such that it can be accessed and used by conveniently
+using some standardised methods.
+
+The package has the following goals, tasks and features:
+%
+\begin{itemize}
+\item
+manage document metadata and write them to the PDF output file;
+\item
+set up and use templates for formatting document data, e.g.\ for title pages;
+\item
+assist in assembling and displaying document license information;
+\item
+facilitate basic internationalisation and localisation;
+\item
+provide preset texts and common license statements
+in different languages.
+\end{itemize}
+%
+Using the structures provided by the packages makes particular sense
+if you can rely on predefined text and formatting or if you have a couple
+of similar documents for which you can define suitable templates.
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\section{Usage}
+\label{sec:usage}
+
+To use the package \textsf{metastr}, add the command
+%
+\begin{center}
+|\usepackage{metastr}|
+\end{center}
+%
+to the preamble of the \LaTeX{} document.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Defining Strings}
+\label{sec:def}
+
+\DescribeMacro{\metadef}
+\DescribeMacro{\metaset}
+The package supplies registers for storing data.
+Registers need to be declared before they can be filled or used
+(unless the package option |checkdef=false| is set,
+see \secref{sec:options}).
+A new register \textit{reg} is declared by the command:
+%
+\begin{center}
+|\metadef{|\textit{reg}|}|
+\end{center}
+%
+The register \textit{reg} can be filled
+with the value \textit{def}
+by the command:
+%
+\begin{center}
+|\metaset{|\textit{reg}|}{|\textit{def}|}|
+\end{center}
+%
+
+The package declares a couple of registers for storing standard metadata.
+The basic set of registers consists of:
+%
+\begin{center}
+\begin{tabular}{ll}
+|title| & document title
+\\
+|subtitle| & document subtitle
+\\
+|author| & document author
+\\
+|location| & location associated to the document
+\\
+|date| & document date
+\\
+|subject| & `subject' of the document
+\\
+|keywords| & (a list of) keywords describing the document
+\\
+|titletext| & composition register for title
+\end{tabular}
+\end{center}
+%
+
+The register |titletext| composes information
+for printing the title
+(such as |title|, |subtitle|, |author|, |location| and |date|).
+It can serve a similar purpose as the \LaTeX{} command |\maketitle|.
+
+Finally, there are some auxiliary registers:
+%
+\begin{center}
+\begin{tabular}{ll}
+|language| &
+main language of the document
+\\
+|url| &
+URL of the document or additional info on it
+\\
+|urlmessage| &
+message to describe the document URL
+\\
+|source| &
+name of the source file
+\\
+|draft| &
+indicator of draft version
+\end{tabular}
+\end{center}
+%
+The register |language| specifies
+the main language used in the document.
+This should be a two-letter language code (\textit{ln})
+potentially followed by two-letter country code
+(\textit{ln}|-|\textit{CN}) such as |en| or |en-GB|.
+The language has some impact on selecting
+register variants, see \secref{sec:variants} and \secref{sec:language},
+it should therefore be set by the command:
+%
+\begin{center}
+|\metasetlang|[|*|]|{|\textit{ln-CN}|}|
+\end{center}
+%
+The starred version declares the language for PDF metadata
+rather than the document contents.
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Working with Strings}
+\label{sec:work}
+
+\DescribeMacro{\metaget}
+A register \textit{reg} can be read out by the macro:
+%
+\begin{center}
+|\metaget[]{|\textit{reg}|}{|\textit{def}|}|
+\end{center}
+%
+Note that the (empty) argument in square brackets is mandatory,
+it cannot be left out, see \secref{sec:variants}
+for further details on its purpose.
+This is because |\metaget| must be robust so that its output
+can be processed for writing (optional arguments make a macro fragile).
+In case the register \textit{reg} has not been filled,
+|\metaget| returns nothing.
+
+\DescribeMacro{\metaif}
+Sometimes one may want to test whether a register is filled or not,
+e.g.\ in order to display a default value otherwise.
+This can be achieved by the conditional:
+%
+\begin{center}
+|\metaif[]{|\textit{reg}|}{|\textit{true}|}{|\textit{false}|}|
+\end{center}
+%
+If the register \textit{reg} is filled, return \textit{true}
+otherwise \textit{false}.
+Again, the argument in square brackets is mandatory.
+
+\DescribeMacro{\metaunset}
+The following command cleans a register \textit{reg}
+which has previously been filled:
+%
+\begin{center}
+|\metaunset{|\textit{reg}|}|
+\end{center}
+%
+Note that cleaning is different from filling an empty string
+when it comes to the conditional |\metaif|
+which evaluates true for an empty string but false for a clean register.
+
+\DescribeMacro{\metaappend}
+\DescribeMacro{\metaprepend}
+\DescribeMacro{\metaaddsep}
+The content of registers can be manipulated by some commands.
+To append or prepend a string to a register,
+use the commands:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaappend{|\textit{reg}|}{|\textit{def}|}|\\
+|\metaprepend{|\textit{reg}|}{|\textit{def}|}|\\
+|\metaaddsep{|\textit{reg}|}{|\textit{sep}|}{|\textit{def}|}|
+\end{tabular}
+\end{center}
+%
+The latter command |\metaaddsep| is designed to compose lists with separators,
+it appends the separator \textit{sep}
+and the value \textit{def} unless the register is clean,
+in which case it is set to \textit{def} without the separator \textit{sep}.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{String Variants}
+\label{sec:variants}
+
+A versatile feature of the registers is that they can be provided
+in several variants.
+These variants can be used for producing different representations
+of the same register depending on the intended situation.
+For example, a title could be given in a fully formatted version
+|print| for printing, a bare version for metadata
+and a shortened version for headings.
+Similarly, translations to different languages
+could be stored as different versions of the same register,
+see \secref{sec:language}.
+Moreover, certain attributes related to the registers
+could be stored in additional variants.
+
+For example, the register |titletext| exists in
+the default variant (mainly intended for writing out metadata)
+and the |print| variant
+(for printing out a combination of title data on the title page).
+The default variant expands to a combination
+of |draft|, |title| and |subtitle|
+(as far as filled):
+%
+\begin{center}
+[\textit{draft}: ]\textit{title}[ -- \textit{subtitle}]
+\end{center}
+%
+The |print| variant is accessed by the command:
+%
+\begin{center}
+|\metapick[print]{titletext}|
+\end{center}
+%
+It expands to four lines
+containing |title|, |subtitle| + |draft|, |author| and |location| + |date|
+(as far as filled):
+%
+\begin{center}
+\textit{title}\\
+\textit{subtitle} |\par| \textit{draft}\\
+\textit{author}\\
+\textit{location}, \textit{date}
+\end{center}
+%
+The formatting style of each line is given
+by the variant |style| of the first register on this line;
+the vertical space above each line is
+produced by the variant |skip|.
+Two items on a single line are separated by the variant |sep|
+of the second register;
+an unfilled |sep| variant puts the two items on individual lines
+(by default this applies to |subtitle| and |draft|).
+In this way the layout of the title display on the title page
+can be adjusted conveniently
+(by default it mimics the \LaTeX{} command |\maketitle|
+in the class \textsf{article}).
+
+Variants are always specified by an argument |[|\textit{var}|]|
+in square brackets preceding the register |{|\textit{reg}|}|.
+This argument is optional for commands
+which set registers and which can be fragile;
+it is however \emph{mandatory} for macros which read
+the register content and whose output needs to be expandable
+into the output stream
+(even though the register is not optional,
+it is more uniform to stick with square brackets to specify the variant).
+The main declaration involving variants is:
+%
+\begin{center}
+|\metaset[|\textit{var}|]{|\textit{reg}|}{|\textit{def}|}|
+\end{center}
+%
+This command defines the register \textit{reg} in variant \textit{var}
+as \textit{def}.
+The default variant is the empty string,
+while the variant |print| is intended for printed output.
+The variant string is obtained by:
+%
+\begin{center}
+|\metaget[|\textit{var}|]{|\textit{reg}|}|
+\end{center}
+
+\DescribeMacro{\metapick}
+The variant mechanism can become powerful
+through macros which fall back to default variants
+if the desired variant has not been filled explicitly:
+%
+\begin{center}
+|\metapick[|\textit{var}|]{|\textit{reg}|}|
+\end{center}
+%
+This macro tests whether the variant \textit{var},
+the language variant \textit{ln}
+specified through |\metasetlang{|\textit{ln}|}|,
+the generic (empty) variant
+or a fallback language variant have been specified.
+If so, their value is returned (in this order of preference).
+Importantly, the intended variant \textit{var} is passed along
+to the evaluation of \textit{reg} as the argument `|#1|' in
+the definition string \textit{def} of |\metaset|.
+This allows to define a register in one generic variant
+which composes other registers in more specific variants.
+To that end reference registers should be accessed by the construct:
+%
+\begin{center}
+|\metaset{|\textit{reg1}|}{|\ldots|\metapick[#1]{|\textit{reg2}|}|\ldots|}|
+\end{center}
+%
+When this register is accessed by
+|\metapick[|\textit{var}|]{|\textit{reg1}|}|,
+it will read the default variant of \textit{reg1}
+which will pass on to \textit{reg2} in \textit{var}
+(rather than in the default variant).
+
+\DescribeMacro{\metaifpick}
+\DescribeMacro{\metacompose}
+There also exist a corresponding conditional:
+%
+\begin{center}
+|\metaifpick[|\textit{var}|]{|\textit{reg}|}|%
+ |{|\textit{true}|}{|\textit{false}|}|
+\end{center}
+%
+This command tests whether any of the above variants \textit{var}
+have been filled.
+Another convenient macro to more efficiently compose strings is:
+%
+\begin{center}
+|\metacompose[|\textit{var}|]{|\textit{reg}|}|%
+ |{|\textit{prefix}|}{|\textit{postfix}|}{|\textit{empty}|}|
+\end{center}
+%
+It returns the intended register value with prefix string \textit{prefix}
+and suffix string \textit{suffix} if any of the above variants
+have been filled; otherwise it returns \textit{empty}.
+For example, the prefix and/or suffix could be separators for
+displaying the content of an optional register.
+
+In dealing with variants,
+the following commands specify the variant \textit{var}
+as an optional argument |[|\textit{var}|]|:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaset[|\textit{var}|]{|\textit{reg}|}{|\textit{def}|}|\\
+|\metaunset[|\textit{var}|]{|\textit{reg}|}|\\
+|\metaappend[|\textit{var}|]{|\textit{reg}|}{|\textit{def}|}|\\
+|\metaprepend[|\textit{var}|]{|\textit{reg}|}{|\textit{def}|}|\\
+|\metaaddsep[|\textit{var}|]{|\textit{reg}|}{|\textit{sep}|}{|\textit{def}|}|
+\end{tabular}
+\end{center}
+%
+For the following macros, specifying the variant \textit{var}
+as |[|\textit{var}|]| is \emph{mandatory}:
+%
+\begin{center}
+|\metaget[|\textit{var}|]{|\textit{reg}|}|\\
+|\metapick[|\textit{var}|]{|\textit{reg}|}|\\
+|\metaifpick[|\textit{var}|]{|\textit{reg}|}|%
+ |{|\textit{true}|}{|\textit{false}|}|\\
+|\metacompose[|\textit{var}|]{|\textit{reg}|}|%
+ |{|\textit{prefix}|}{|\textit{postfix}|}|
+\end{center}
+%
+Here, the default variant is accessed by an empty argument \textit{var}.
+
+To illustrate a construction using variants,
+let us consider the above register |titletext|.
+It is defined in the generic variant as:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaset{titletext}{%|\\
+| \metacompose[#1]{draft}{}{: }{}%|\\
+| \metapick[#1]{title}%|\\
+| \metacompose[#1]{subtitle}{\metaget[sep]{subtitle}}{}{}}|
+\end{tabular}
+\end{center}
+%
+This expands to the prefix `\textit{draft}: ' (if available),
+the main title `\textit{title}'
+and the suffix ` -- \textit{subtitle}' (if available).
+The |print| variant to output a full title for the document is defined by:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaset[print]{titletext}{%|\\
+| \metatitleline[print]{title}%|\\
+| \metatitlelinetwo[print]{subtitle}[print]{draft}%|\\
+| \metatitleline[print]{author}%|\\
+| \metatitlelinetwo[print]{location}[print]{date}}|
+\end{tabular}
+\end{center}
+%
+Here, the macros |\metatitleline|[|two|] produce a title line
+consisting of one or two items.
+The single-item version is defined as:
+%
+\begin{center}
+\begin{tabular}{l}
+|\def\metatitleline[#1]#2{%|\\
+| \metacompose[#1]{#2}|\\
+| {\metaget[skip]{#2}\begingroup\metaget[style]{#2}}|\\
+| {\par\endgroup}{}}|
+\end{tabular}
+\end{center}
+%
+If register |#2| is filled,
+this expands to the vertical skip defined by the variant |skip|
+and an encapsulated paragraph of the register value
+in the layout defined by the variant |style|.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Write Document Metadata}
+\label{sec:meta}
+
+The contents of certain registers can be written out to
+PDF files as metadata using the package \textsf{hyperref}
+and the extension \textsf{hyperxmp}.
+
+\DescribeMacro{\metawritepdfinfo}
+The basic metadata registers are written out by |\metawritepdfinfo|
+using \textsf{hyperref}.
+The mapping between \textsf{metastr} registers
+and \textsf{hyperref} |\hypersetup| options is given by:
+%
+\begin{center}
+\begin{tabular}{l@{\quad$\to$\quad}l}
+|titletext| & |pdftitle|
+\\
+|author| & |pdfauthor|
+\\
+|subject| & |pdfsubject|
+\\
+|keywords| & |pdfkeywords|
+\end{tabular}
+\end{center}
+%
+Here, |titletext| is used instead of |title| to compose information
+from the registers |draft|, |title| and |subtitle| (as far as filled).
+Note that |\metawritepdfinfo| will be effective
+only when invoked before the contents of the first page are written out.
+
+\DescribeMacro{\metawritepdfaux}
+Auxiliary metadata is written out using \textsf{hyperxmp}
+by the command |\metawritepdfaux| with the mapping:
+%
+\begin{center}
+\begin{tabular}{l@{\quad$\to$\quad}l}
+|url| & |pdfurl|
+\\
+|source| & |pdfsource|
+\end{tabular}
+\end{center}
+
+\DescribeMacro{\metawritepdfpreamble}
+Some metadata must be written out sufficiently early,
+i.e.\ in the document preamble, in order to go into effect.
+These include the language settings,
+and they are written out by |\metawritepdfpreamble|
+with the mapping:
+%
+\begin{center}
+\begin{tabular}{l@{\quad$\to$\quad}l}
+|language| & |pdflang|
+\\
+|language| variant |[meta]| & |pdfmetalang|
+\\
+ & |keeppdfinfo|
+\end{tabular}
+\end{center}
+%
+Note that |pdfmetalang| is a setting of \textsf{hyperxmp}
+and will be ignored if the package is not loaded.
+Furthermore, the \textsf{hyperxmp} option |keeppdfinfo|
+will be set unless the package option |xmppdfinfo=false| is set.
+
+\DescribeMacro{\metawritepdfcontact}
+A contact can be specified within PDF files
+in a standardised format using \textsf{hyperxmp}.
+The command |\metawritepdfcontact| passes on the following
+registers with the mapping:
+%
+\begin{center}
+\begin{tabular}{l@{\quad$\to$\quad}l}
+|contactaddress| & |pdfcontactaddress|
+\\
+|contactpostcode| & |pdfcontactpostcode|
+\\
+|contactcity| & |pdfcontactcity|
+\\
+|contactregion| & |pdfcontactregion|
+\\
+|contactcountry| & |pdfcontactcountry|
+\\
+|contactemail| & |pdfcontactemail|
+\\
+|contacturl| & |pdfcontacturl|
+\end{tabular}
+\end{center}
+
+\DescribeMacro{\metawritepdfrights}
+A document copyright statement, see \secref{sec:rights},
+is recorded within the PDF file by |\metawritepdfrights|
+using \textsf{hyperxmp} with the mapping:
+%
+\begin{center}
+\begin{tabular}{l@{\quad$\to$\quad}l}
+|rightstext| & |pdfcopyright|
+\\
+|licenseurl| & |pdflicenseurl|
+\end{tabular}
+\end{center}
+%
+
+\DescribeMacro{\metawritepdf}
+\DescribeMacro{writepdf}
+Finally, it makes sense to write out PDF metadata automatically.
+This is controlled by filling or clearing certain variants \textit{var}
+of the register |writepdf|:
+%
+\begin{center}
+\begin{tabular}{rl}
+&|\metaset[|\textit{var}|]{writepdf}{}|\\
+or&|\metaunset[|\textit{var}|]{writepdf}|
+\end{tabular}
+\end{center}
+%
+If the variant |auto| is filled (default),
+PDF metadata is written automatically
+at the beginning of the |document| block
+by calling |\metawritepdf|.
+The command |\metawritepdf| calls
+the commands |\metawritepdf|\ldots{}
+depending on whether the variants |info|, |aux|, |preamble|,
+|contact|, |rights| of the register |writepdf| are filled;
+the variants |info|, |aux|, |preamble| are enabled by default,
+the variants |contact|, |rights| need to be enabled explicitly.
+
+Note that the basic metadata such as |author| and |title|
+do not have to be defined already in the preamble,
+but (depending on the combination of drivers and packages)
+they can be set before the contents of the first page
+are shipped out to the PDF file.
+If the basic registers are to be declared on the first page,
+one should disable their automatic writing by
+|\metaunset[info]{writepdf}|.
+When the corresponding registers have been filled,
+(but no later than the end of the first page),
+they need to be written manually
+by invoking |\metawritepdfinfo|.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Copyright and Licenses}
+\label{sec:rights}
+
+Specifying a copyright statement and a license is very useful because it
+makes the allowed (re)use of the provided material evident to the reader.
+However, it also takes some efforts to set things up properly.
+The package \textsf{metastr} provides some default texts to
+state the license for a couple of well-established licenses.
+For instance, the set of Creative Commons licenses has become a standard
+to mark the intended (re)use of a document involving creative content.
+For documents related to software, there is a number of
+standard software licenses to choose from.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\paragraph{Registers.}
+
+The package declares the following registers to state the copyright:
+%
+\begin{center}
+\begin{tabular}{ll}
+|copyrightmark| & `\copyright' (|print| variant) or ``Copyright''
+\\
+|copyrightdate| & copyright date
+\\
+|copyrightowner| & copyright owner
+\\
+|copyrightstatement| & combines:
+|...mark| + |...date| + |...owner|
+\\
+|copyrightmessage| & a message explaining the copyright situation
+\end{tabular}
+\end{center}
+%
+The package declares the following registers to state the license:
+%
+\begin{center}
+\begin{tabular}{ll}
+|licensemessage| & licensing message
+\\
+|licenseprovider| & license provider
+\\
+|licenseversion| & license version
+\\
+|licenselogo| & license logo inclusion
+\\
+|licenselogomessage| & display the license logo
+\\
+|licenseurl| & URL with license text and details
+\\
+|licenseurlmessage| & display the license URL
+\end{tabular}
+\end{center}
+%
+Furthermore, there are some related auxiliary registers:
+%
+\begin{center}
+\begin{tabular}{ll}
+|partof| & specifies the work this document is a part of
+\\
+|partofmessage| & a message declaring being part of
+\\
+|attributionmessage| & a message declaring attributions
+\\
+|rightstext| & a composition template for all of the above
+\end{tabular}
+\end{center}
+%
+The above information is compiled automatically in the register |rightstext|.
+It can be written as PDF metadata
+as well as printed with formatting:
+%
+\begin{center}
+|\metapick[print]{rightstext}|
+\end{center}
+%
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\paragraph{Presets.}
+
+The package provides a couple of presets
+for commonly used copyright statements and licenses.
+These are selected by:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metacopyright{|\textit{preset}|}|\\
+|\metalicense{|\textit{preset}|}|
+\end{tabular}
+\end{center}
+%
+The following \textit{preset} values
+provide the associated copyright statements:
+%
+\begin{center}
+\begin{tabular}{ll}
+|plain| & This work is protected by copyright.
+\\
+|parts| & This work as well as its parts is protected by copyright.
+\\
+|doc| & This document is protected by copyright.
+\\
+|doc-parts| & This document as well as its parts is protected by copyright.
+\\
+|reserved| & All rights reserved.
+\\
+|publicdomain| & This work is dedicated to the public domain.
+\end{tabular}
+\end{center}
+%
+The following \textit{preset} values
+provide the associated license statements:
+%
+\begin{center}
+\begin{tabular}{ll}
+|consent| &
+\parbox[t]{0.75\textwidth}{\raggedright
+ Reproduction of any part of this work in any form
+ without prior written consent
+ \textit{of the author}
+ is not permissible.
+}
+\\
+\vphantom{$\hat A$}%
+|consent-noncom| &
+\parbox[t]{0.75\textwidth}{\raggedright
+ Reproduction of any part of this work in any form
+ without prior written consent
+ \textit{of the author}
+ is permissible only for private, scientific and non-commercial use.
+ \vphantom{g}}
+\\
+\vphantom{$\hat A$}%
+|lppl| &
+\parbox[t]{0.75\textwidth}{\raggedright
+ This work may be distributed and/or modified under the
+ conditions of the LaTeX Project Public License, either version \textit{1.3}
+ of this license or (at your option) any later version.\\
+ \url{http://www.latex-project.org/lppl.txt}
+}
+\end{tabular}
+\end{center}
+%
+The license URL will be selected where available.
+The italicised parts of the license statement can be customised
+by the registers |licenseversion| and |licenseprovider|.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\paragraph{Creative Commons Licenses.}
+
+A Creative Commons license can be selected by the command:
+%
+\begin{center}
+|\metalicensecc{|\textit{license}|}|
+\end{center}
+%
+The parameter \textit{license} specifies the type of CC license:
+%
+\begin{center}
+\begin{tabular}{ll}
+|by| & Attribution \\
+|by-sa| & Attribution-ShareAlike \\
+|by-nd| & Attribution-NoDerivatives \\
+|by-nc| & Attribution-NonCommercial \\
+|by-nc-sa| & Attribution-NonCommercial-ShareAlike \\
+|by-nc-nd| & Attribution-NonCommercial-NoDerivatives \\
+|zero| & CC0 public domain declaration \\
+|pd| & generic public domain declaration
+\end{tabular}
+\end{center}
+%
+The appropriate license URL and CC logo is selected
+by the command as well, e.g.
+%
+\begin{center}
+\includegraphics{doclicense-CC-by-sa}\\
+\url{https://creativecommons.org/licenses/by-sa/4.0/}
+\end{center}
+%
+Note that |pd| is not a CC license, but it declares
+that the document is in the public domain by
+|\metacopyright{publicdomain}|
+and it selects the corresponding CC logo for public domain content.
+
+A version of the CC license can be specified by
+the register |licenseversion|.
+The default version is |4.0| (international), further available versions are
+|3.0| (unported) as well as |2.5|, |2.0|, |1.0| (generic).
+For the CC0 license |zero|, the only available version is |1.0| (universal)
+which is the default.
+
+Displaying the logo requires (manual) loading
+of the package \textsf{graphicx};
+furthermore the package \textsf{doclicense} containing the logo files
+must be present.
+The display of the logo can be disabled by the package option |cclogo=false|.
+The logo display is coded by the following definitions
+which can be customised:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaset[print]{licenselogomessage}{%|\\
+| \centerline{\metapick[#1]{licenselogo}}}|\\
+|\metaset[cmd]{licenselogo}{\includegraphics{#1}}|
+\end{tabular}
+\end{center}
+
+Various registers and variants of the selected CC license exist.
+The registers specific to CC licenses are:
+%
+\begin{center}
+\begin{tabular}{ll}
+|licencecc| & CC license identifier
+\\
+|licenceccver| & CC license version
+\\
+|licenceccfull| & full license descriptor
+\end{tabular}
+\end{center}
+%
+The variants specific to CC licenses are:
+%
+\begin{center}
+\begin{tabular}{ll}
+\textit{ln} & representation in language \textit{ln}
+\\
+|icon| & CC icon (package \textsf{ccicons} required),
+e.g. \ccLogo\ccAttribution\ccShareAlike
+\\
+|url| & license URL
+\\
+|ident| & CC identifier, e.g.\ `BY-SA'
+\\
+|short| & short form, e.g.\ `CC BY-SA'
+\\
+|logo| & logo filename (package \textsf{doclicense})
+\end{tabular}
+\end{center}
+%
+For example, a full license descriptor is displayed by
+|\metapick[]{licenseccfull}|:
+Creative Commons License ``Attribution-ShareAlike 4.0 International''.
+The license icon can be displayed by
+|\metaget[icon]{licensecc}|: \ccLogo\ccAttribution\ccShareAlike{}
+(this requires the package \textsf{ccicons} to be loaded).
+Note that displaying the full license message |licensemessage|
+in variant |print| in some languages
+may produce quotation marks not declared in default fonts
+causing an error; this can be avoided to some extent by
+loading an appropriate packages for internationalisation
+such as \textsf{babel}.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Languages}
+\label{sec:language}
+
+A principal application of the register variants is to
+implement internationalisation and localisation.
+Evidently, this is a tricky subject
+due to various particularities of languages,
+but the register variants can be used
+to specify and select different language representations
+for some commonly used text elements.
+For example, the copyright and license statements in \secref{sec:rights}
+are internationalised (to some extent).
+This makes them conveniently usable in the appropriate language.
+Note that the language presets to be loaded
+need to be specified explicitly by the package option |loadlang|,
+see \secref{sec:options}.
+
+The idea is to understand the variant \textit{var}
+of a register \textit{reg} to be its representation in the language
+\textit{var}=\textit{ln}[|-|\textit{CN}].
+The default (empty) variant as well as specific purpose variants
+(such as |print|) should be provided in the
+document language or a fallback language (such as English).
+The macro |\metapick[|\textit{var}|]{|\textit{reg}|}|
+then selects the appropriate language representation
+or falls back to the default language.
+Here \textit{var} can specify a particular language or a particular purpose.
+Then, |\metapick| will pick (in this order of preference):
+%
+\begin{itemize}
+\item
+the language or purpose \textit{var},
+\item
+the document language specified by |\metasetlang| (if available),
+\item
+the document language specified by |\metasetlang|
+with country code stripped (if available),
+\item
+the default variant,
+\item
+the fallback language (first of package option |loadlang|).
+\end{itemize}
+%
+Note that nesting of |\metapick|
+via |\metapick[#1]{|\textit{reg}|}|
+passes along the original variant
+\textit{var} in the parameter |#1|.
+This mechanism allows to specify some non-specific elements
+in a universal language while the appropriate language is
+selected where available.
+
+\macro{\metaterm}
+\macro{\metatranslate}
+\macro{\metasettest}
+The package reserves registers of the form |term-|\textit{term}
+for storing terms in various (language) representations.
+A couple of such term registers describing common entities in typesetting
+are defined by the package:
+%
+\begin{center}
+\begin{tabular}[t]{ll}
+|title|&Title\\
+|abstract|&Abstract\\
+|copyright|&Copyright\\
+|preface|&Preface\\
+|part|&Part\\
+|chapter|&Chapter\\
+|section|&Section\\
+|subsection|&Subsection\\
+|paragraph|&Paragraph
+\end{tabular}
+\qquad\qquad
+\begin{tabular}[t]{ll}
+|appendix|&Appendix\\
+|page|&Page\\
+|figure|&Figure\\
+|table|&Table\\
+|contents|&Contents\\
+|listfigure|&List of Figures\\
+|listtable|&List of Tables\\
+|references|&References\\
+|index|&Index\\
+|draft|&DRAFT
+\end{tabular}
+\end{center}
+%
+These are provided in different languages for convenient
+internationalisation
+(this can be viewed as a low-key implementation of some of the features
+of the \href{https://ctan.org/pkg/babel}{\textsf{babel}} package).
+Additional term registers can be defined by the user.
+Term registers are accessed by the macros:
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaterm{|\textit{term}|}|\\
+|\metatranslate[|\textit{ln}|]{|\textit{term}|}|\\
+|\metasetterm[|\textit{ln}|]{|\textit{reg}|}{|\textit{def}|}|
+\end{tabular}
+\end{center}
+%
+The macro |\metaterm| obtains the term \textit{term}
+in the default language
+(it invokes |\metapick[]| with empty variant),
+while |\metatranslate| uses any other language \textit{ln}.
+The macro |\metasetterm| declares and fills a term register \textit{term}
+(in a particular language \textit{ln}).
+Note that therefore it is not necessary to declare term registers
+explicitly by |\metadef|.
+
+The PDF metadata are written out in the metadata language variant
+specified by |\metasetlang*|;
+otherwise in the default document language
+specified by |\metasetlang| is used.
+Some registers can even be written out
+in several alternative language versions
+using the package \textsf{hyperxmp},
+namely |title|, |subject| and |rightstext|.
+The set of alternative languages is specified by
+(before invoking the respective command |\metawritepdf...|):
+%
+\begin{center}
+\begin{tabular}{l}
+|\metaset[altlang]{title}{|\textit{languages}|}|\\
+|\metaset[altlang]{subject}{|\textit{languages}|}|\\
+|\metaset[altlang]{rightstext}{|\textit{languages}|}|
+\end{tabular}
+\end{center}
+%
+Here, \textit{languages} is a comma-separated list of language identifiers
+and for each identifier \textit{ln}
+the information is written out in the respective language variant.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Package Options}
+\label{sec:options}
+
+General options for the package can be selected by the commands:
+%
+\begin{center}
+\begin{tabular}{rl}
+&|\usepackage[|\textit{opts}|]{metastr}|
+\\
+or&|\PassOptionsToPackage{|\textit{opts}|}{metastr}|
+\end{tabular}
+\end{center}
+%
+|\PassOptionsToPackage| must be used before |\usepackage|.
+\textit{opts} is a comma-separated list of options.
+
+The following options are available:
+%
+\begin{itemize}
+\item |hyperref|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |true|) --
+use the package \textsf{hyperref} to write metadata to PDF.
+\item |hyperxmp|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |true|) --
+use the auxiliary package \textsf{hyperxmp}
+to write additional metadata to PDF.
+\item |checkdef|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |true|) --
+check whether registers have been previously declared
+when filling them.
+\item |cclogo|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |true|) --
+display CC logo from \textsf{doclicense} package.
+\item |cclogocurr=dollar|\textbar|euro|\textbar|yen|
+(initially set to |dollar|) --
+select currency symbol for Creative Commons NonCommercial logos.
+\item |xmppdfinfo|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |true|) --
+write the basic PDF info block
+when using the auxiliary package \textsf{hyperxmp};
+if this option is set,
+\textsf{hyperxmp} is loaded with the option |keeppdfinfo|.
+\item |draft|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |false|) --
+fill |draft| register with ``DRAFT''.
+\item |course|[|=true|\textbar|false|]
+(no value implies |true|, initially set to |false|) --
+Setup extended registers for course materials, see \secref{sec:extras}.
+\item |loadlang=|\textit{ln-1}\texttt{\textbar}\textit{ln-2}%
+ \texttt{\textbar}|...|\texttt{\textbar}\textit{ln-n}
+(bar-separated list w/o spaces, initially set to |en|) --
+Load presets for languages \textit{ln-1}, \textit{ln-2}, \ldots, \textit{ln-n},
+see \secref{sec:language}.
+The first language \textit{ln-1} serves as the fallback variant.
+Available internationalisations currently consist of:
+\begin{center}
+\begin{tabular}{ll}
+|en|& English\\
+|de|& German\\
+|fr|& French\\
+|es|& Spanish
+\end{tabular}
+\end{center}
+\end{itemize}
+%
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Extras}
+\label{sec:extras}
+
+The package can provide some special purpose registers on request.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\paragraph{Course Materials.}
+
+A couple of registers for course materials are provided
+upon setting the package option |course|:
+%
+\begin{center}
+\begin{tabular}{ll}
+|course| & title of course
+\\
+|material| & description of document material
+\\
+|period| & period where course takes place
+\\
+|institution| & institution where course is given
+\\
+|instructor| & instructor of course
+\end{tabular}
+\end{center}
+%
+
+The variant |course| of the register |titletext| displays a
+compilation of these registers for display on a title page:
+%
+\begin{center}
+\textit{course}\\
+\textit{material} |\par| \textit{draft}\\
+\textit{institution}, \textit{period}\\
+\textit{instructor}
+\end{center}
+%
+Furthermore, the registers
+|title|, |subtitle|, |author|, |location| and |date| are
+diverted to |course|, |material|, |instructor|,
+|institution| and |period| respectively.
+Consequently, their values are automatically written as PDF metadata,
+but it is certainly possible to override them with custom values.

+The package \href{http://ctan.org/pkg/hyperref}{\textsf{hyperref}}
+writes the arguments of |\author| and |\title|
+unless the package option |pdfusetitle=false| is declared (at load time).
+\item
+The package \href{http://ctan.org/pkg/hyperxmp}{\textsf{hyperxmp}}
+writes the arguments of |\author| and |\title|.
+\item
+The package \href{http://ctan.org/pkg/exframe}{\textsf{exframe}}
+writes the |\exercisedata| registers
+|author|, |title|, |subject| and |keyword|
+unless the package option |pdfdata=off| is specified.
+\item
+The package \href{http://ctan.org/pkg/beamer}{\textsf{beamer}}
+writes the arguments of |\author|, |\title|, |\subject| and |\keywords|.
+\item
+The package \href{http://ctan.org/pkg/gitver}{\textsf{gitver}}
+writes |pdfsubject| unless the package option |nopdfinfo| is specified.
+\item
+Various packages to prepare articles for publication in journals.
+\end{itemize}
+%
+Their mechanisms may be in competition
+with the ones of the present package \textsf{metastr}.
+In order to make the packages work together on the same set of data,
+the most promising option which should work in many cases is the following:
+Fill the registers of \textsf{metastr}
+with the desired values.
+Then pass them on to the structures
+of the other package(s) using |\metaget| or |\metapick|.
+Since the latter commands are robust,
+the other structures ought to be able to handle them without further ado.
+To avoid potential conflicts, multiple writing of (basic) metadata
+should be disabled. For the \textsf{metastr} package this is achived by:
+%
+\begin{center}
+\begin{tabular}{rl}
+&|\metaunset[info]{writepdf}|\\
+or&|\metaunset[auto]{writepdf}|

+%
+% This section provides an example of how to apply
+% some of the \textsf{metastr} mechanisms and licenses.
+%
+% Some lines in the example are commented by |%%| for easy experimenting.
+%
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Preamble.}
+%
+% Standard document class:
+% \begin{macrocode}
+\documentclass[12pt]{article}
+% \end{macrocode}
+
+% Use package \textsf{geometry} to set the page layout;
+% adjust the paragraph shape:

+\geometry{layout=a4paper}
+\geometry{paper=a4paper}
+\geometry{margin=2.5cm}
+\parindent0pt
+\parskip1ex
+% \end{macrocode}
+
+% Declare some options for the package \textsf{hyperref};
+% it does not hurt to load it explicitly
+% although \textsf{metastr} will invoke it by default if not loaded:
+% \begin{macrocode}
+\PassOptionsToPackage{bookmarks=true}{hyperref}
+\usepackage{hyperref}
+% \end{macrocode}
+
+% Set some options for the \textsf{metastr} package:
