Crowdsourcing Translations/Developer Documentation

What is it?

This is a plugin that allows "crowdsourcing" the translation of Geeklog, i.e. once installed, it allows users to contribute translations of Geeklog's user interface texts for other languages.

This is a being developed by Benjamin Talic as a project during the Google Summer of Code 2013.

Major Design Decisions

• Any logged-in user should be able to contribute a translation
• Users can be blocked from contributing by the Admin
• Ideally, the plugin should also allow translations of plugins (bundled and 3rd party). We'll start with core texts but try to keep things generic, adding plugin support later when possible.
• To be able to find translations on a page at plugin installation pages are mapped into the database, data on which phrases on which pages is saved along with which pages are included in it
• Remote contribution is allowed via a form
• Gamification is added to the plugin
• The plugin is placed on the left side block - the left side block is shown on more pages

Considerations

• Ideally, translators should be able to see the text strings in context to help with the translation. - implemented
  • If that turns out not to be possible, we'll show them without context.
• It's acceptable if the translation option slows things down. If it slows down things noticably, add a "translation mode", so users can decide between using the site normally or helping with the translation. - not necessary
