= Henning's Rosetta Presentation =

This is a video presentation that I prepared as a replay of a spontaneous presentation I gave in Dallas to my new squad. It, like it's real-life predecessor, is intended to give Launchpad developers an introduction to Launchpad Translations and ease the learning curve when starting to hack on its code.

== The Presentation ==

The presentation has four parts which build on each other.

 * [[http://vimeo.com/eggersfamily/rosetta-presentation-1|Part 1]] introduces you to the basics of translating software and the standard gettext workflow.
 * [[http://vimeo.com/eggersfamily/rosetta-presentation-2|Part 2]] explains how the gettext files are mapped into the Launchpad database.
 * Part 3 shows how project maintainers, the Ubuntu guys and translators use Launchpad to get software translated.
 * Part 4 lifts the hood and gives you a tour of the processes underneath Launchpad Translations.

== The support material ==

Stuff that is referenced in the video. Please add whatever I forgot.

There is also a [[https://wiki.ubuntu.com/UbuntuDeveloperWeek/Sessions/LaunchpadTranslationsUnderTheHood|similar presentation]] that [[https://launchpad.net/~adiroiban|Adi]] and I gave on IRC during an Ubuntu Developer Week.

=== Part 1 ===

 * [[http://www.gnu.org/software/gettext/manual/gettext.html|The GNU gettext manual]]

Here is an example POT file (i.e. a PO file without translations). The presentation does not mention the header which you see here which is marked by an empty msgid and contains meta information about the file.

{{{
msgid ""
msgstr ""
"PO-Revision-Date: 2005-05-03 20:41+0100\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Content-Type: text/plain; charset=UTF-8\n"

msgid "Thank You"
msgstr ""

msgid "You're welcome"
msgstr ""
}}}

== Part 2 ==

Here is a PNG export of the Dia file that documents the Launchpad Translations database schema.
