Thank you for your work. 

I didn't test your patch. However, here are some late comments about
this suggestion.

I think

  #+TITLEGRAPHICS: [[file:link.pdf]]

would be cleaner.

The last `cond' could be merged with the one above. It looks like
there's unnecessary branching here.

Anyway, it probably should not be included per suggestion above.

Since "short-author" is `parsed', this should be wrapped within
`org-export-data' somehow. You do it below, but it introduces some code
duplication.

> + (org-export-data (plist-get info :email) info)))

You left a dangling parenthesis.

See above. Also, I would move the (format ...) below (or author email)

I would put the "" below (format "[%s]" short-date): it doesn't make
clear there is an else branch otherwise.

See above.

I see.

Re the beamer manual 10.1, we could add the following keywords,
#+short_title, #+short_subtitle, #+short_date , #+institute and
#+short_institute.

Maybe we can have a titlegraphics like,

#+attr_beamer: :titlegraphics t
[[file:link.pdf]]

I've attached some rough patches that does this.  Maybe you can test them?

Nothing really, but when I use title:t, org mode sets a
\title{presentation} in the tex file which overwrites my own title. If
I set title:nil, it sets \title{} still overwriting my own title.

Ah, ok, I think I got using these settings now:

#+startup: beamer
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Boadilla
#+OPTIONS: H:2 num:t title:nil toc:nil

#+BEGIN_LATEX
\author[me]{me and the coauthors}
\title[short title]{long title \\ next line}
\subtitle{subtitle}
\institute[short institute]{long institute}
\maketitle
#+END_LATEX


As I said, all I want is to have a standard title page followed by a
toc, but I need to set also the short version of title, institute and
author.

Well it works, albeit not very elegant.

Best,
Florian

What exactly are you missing from the standard title page support of Org?

Yes, the #+TOC keyword combined with the option toc:nil.

Ah, you were right. I used the builtin org version.

It works now, however, when I set the title:nil is does not produce a
title page at all.

#+BEGIN_LATEX
\maketitle
#+END_LATEX

inserts a title page, but after the table of contents.

Any way to work around that?

Are you sure you are using an up-to-date version of Org?
M-x org-version should return 8.3.something.

Neither that works for me

#+startup: beamer
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Boadilla
#+LATEX_HEADER: \author[me]{me and the coauthors}

#+subtitle: subtitle
#+OPTIONS: H:2 toc:t num:t title:nil

The subtitle is ignored and the resulting tex file still contains
\title{presentation}

Don't know.

\\ at eol is org syntax for forced line break.

Same as me - beamer in org is really niche when you get the hang of it
(still not completely there).

You could use
#+BEAMER_HEADER: instead of #+LATEX_HEADER: - makes it clearer and is
only inserted when exporting to beamer.
