The Debian web site features statistics web pages under http://www.debian.org/intl/l10n. These pages collect statistical data about po-debconf and programs translations.
The statistics are collected daily by a script run under a developer's account on people.debian.org (Denis Barbier account at the time of this writing). These statistics use material gathered by another script run under a developer's account on people.debian.org (Pierre Machard at the time of this writing).
The statistics pages help translators learn about areas that need work such as updates for existing translations or new packages/material needing translation work.
The pages also help translators to grab POT files and start working on new translations as well as PO files and work to complete them.
Even though this system has proven to be highly useful during last years, it still carries a few weaknesses that prevent calling it an overall i18n/l10n infrastructure:
it depends on scripts running under individual developers accounts;
it only gives statistics for the unstable branch of the distribution and thus does not allow to get statistics about l10n in testing during release preparation;
it does not track down the status of the work by translation teams and does no point the reader to the existing translation teams. For that reason, teams have developed their own tracking work method (some parts will be detailed in Section 3.4)
it is not linked to the bug tracking system and does not allow checking whether an incomplete or missing translation has a pending fix in the BTS (and for how long the fix is pending) or in the package development revision control system.
A way to go would be integrating all these needs in a more general i18n/l10n infrastructure.
