Internationalization (i18n) with Drupal

• bilingual site (English/French)
• clean URLs prefixed with language
  • /en/an-english-page
  • /fr/une-page-en-francais
• link pages to their translation in the other language

• Enable modules Content Translation, Locale and Pathauto.

• /admin/settings/language/configure: Language negotiation -> Path prefix only.
• /admin/settings/language/edit/en: set Path Prefix to en
• /admin/settings/language/add: add French
• /admin/settings/language/add: add German
• /admin/settings/language/overview: select German as default language (reason: links to pages in default language don't have any language prefix.) From now, access admin pages with en/admin

Example: /en/admin/content/node-type/page -> Workflow settings -> Multilingual support -> Enabled, with translation

• /en/admin/build/path/pathauto -> Node paths -> Default path pattern

• when creating contents, select language. Example: /node/add/page -> Language -> English
