[Tex/LaTex] How to change author alignment in Beamer

beamerhorizontal alignmenttitles

It appears that different classes set up author layouts using tables.
I would like to render one of these outputs:

Equivalent to \begin{tabular}{rl}:

  Joe Schmoe My Boss
    Jane Doe His Boss

or, equivalent to \raggedleft:

  Joe Schmoe My Boss
   Jane Doe His Boss

from something resembling this M(N)WE:

\documentclass{beamer}

\author{%
Joe Schmoe, My Boss%
\and
Jane Doe, His Boss%
}

\begin{document}
\maketitle
\end{document}

I don't mind using \institute or something equivalent for job title, and I can even drop the job title to see a simple solution.

In some other document classes there is a nice solution involving \preauthor,
which I could modify in my style file.
Unfortunately, I get an unknown command error in Beamer 3 on \preauthor with that code.
Are there equivalent constructs in Beamer?

There is also another approach that uses a tabular environment
but that also fails in Beamer.

Ideally, I would like to change \defbeamertemplate*{title page}{default theme}{... in my beamer style file,
so that I could still use \author{} with all its trimmings in the main file,
but since I do not use authors anywhere else on the slide,
a solution using some kind of box in the main source would work as well.

One option redefining the internal \beamer@author defined in beamerbasetitle.sty (in this way, the definition will be theme-independent) to use a tabular with the desired alignment; you need to use the optional argument to provide a proper information for the author bookmark:

\documentclass{beamer}
\usetheme{Madrid}

\makeatletter
\long\def\beamer@author[#1]#2{%
  \def\insertauthor{\def\inst{\beamer@insttitle}\def\and{\beamer@andtitle}%
  \begin{tabular}{rl}#2\end{tabular}}%
  \def\beamer@shortauthor{#1}%
  \ifbeamer@autopdfinfo%
    \def\beamer@andstripped{}%
    \beamer@stripands#1 \and\relax
    {\let\inst=\@gobble\let\thanks=\@gobble\def\and{, }\hypersetup{pdfauthor={\beamer@andstripped}}}
  \fi%
}
\makeatother

\title{The title}
\author[Joe and Jane]{%
Joe Schmoe, & My Boss \\
Jane Doe, & His Boss
}

\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}

enter image description here

Change \begin{tabular}{rl} to \begin{tabular}{r} above for the other alignment required.

In a comment it has been requested to redefine \and so that it acts as \tabularnewline to separate author rows in the mandatory argument of \author; here's the required modification:

\documentclass{beamer}
\usetheme{Madrid}

\makeatletter
\long\def\beamer@author[#1]#2{%
  \def\and{\tabularnewline}
  \def\insertauthor{\def\inst{\beamer@insttitle}\def\and{\tabularnewline}%
  \begin{tabular}{rl}#2\end{tabular}}%
  \def\beamer@shortauthor{#1}%
  \ifbeamer@autopdfinfo%
    \def\beamer@andstripped{}%
    \beamer@stripands#1 \and\relax
    {\let\inst=\@gobble\let\thanks=\@gobble\def\and{, }\hypersetup{pdfauthor={\beamer@andstripped}}}
  \fi%
}
\makeatother

\title{The title}
\author[Joe \and Jane]{%
Joe Schmoe, & My Boss \and
Jane Doe, & His Boss
}

\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}

[Tex/LaTex] Consistent way to define document title, subtitle, author, affiliation, abstract etc

There are really two questions here: how to define the interface and how to implement it. I'll only tackle the former, because the implementation would require several hours' work.

First you have to decide whether using non standard commands, say \Title and \Author instead of \title and \author. There are many classes around and different realizations. For instance, the standard classes (article, report and book) allow for only one \author command, others want that different authors go in distinct \author commands (amsart does this).

I'll assume you go with \title and multiple \author commands for maximum flexibility. The best approach is, in my opinion, using a key-value syntax.

A document always has a title, and sometimes a short title for the header or a subtitle. I would do it like

\title[
  subtitle=A subtitle,
  short-title=A short title
]{The very long title of this document}

rather than providing a bunch of commands such as \subtitle and \shorttitle: in this way all the data are in one place. Similarly for author information:

\author[
  affiliation=University of Someplace,
  affiliation-secondary=Institute of Silly Investigations,
  address=42, Hidden Road, Someplace,
  email=abigail.uthor@someplace.xy,
  email-current=a.uthor@giggle.com,
  abbreviated-name=A. Uthor,
  thanks=Research grant 1234567890,
]{Abigail Uthor}

\author[
  key=writer,
  corresponding,
  affiliation=University of Nowhere,
  email=winfried.riter@nowhere.nw,
  long-name=Winfried Riter,
]{W. Riter}

\author[
  share=writer,
  email=brutus.c.dull@stanford.edu,
]{B. C. Dull}

Note that I used several keys that can be used or not by your class. For instance, key=writer could make it possible to share affiliation information between two or more authors. The more detailed and classified is the information, the easier will be to implement a set of commands that process it.

Talking of user interface, something like \AtBeginDocument{\maketitleandabstract} is surely not something document authors should be supposed to type. This will be done by the class; the classical approach with \maketitle can be used too.

I'm also keen towards placing this information after \begin{document}. If you do it in this way, you can free yourself from the burden of adding the \maketitle command: just define a articledata environment, whose end automatically issues \maketitle. So

\documentclass{myclass}
<packages>
<definitions>

\begin{document}
\begin{articledata}
\title[...]{...}

\author[...]{...}

\author[...]{...}

\abstract{
  this is the abstract
}

\keywords{
  a list of keywords
}
\end{articledata}

<paper starts here>

\end{document}

With a simple switch you can warn that commands such as \author, \title, \abstract and so on must go in the articledata environment (or issue an error message). It will be also easy to provide a package with a compatibility option that redefines the commands and the environment so that the document becomes compatible with article.
