   Basics
   i18n is the process of making software localizable
   L10n means actually
   • formatting dates, numbers, …
   • translating text
   • adjusting other things (images, …)

   Locale
   Locale instances encapsulate a locale identifier
   Locales define the language and formats to use
   Locales form a hierarchy
   • en is a parent of en_US which is a parent of
   en_US_POSIX
   • Thus items for the en_US locale that do not
   exist, will be used from the en locale if available

   f:translate
   the way of translating you will use most
   
   {f:translate(id: 'my.label.1')}
   translation by label is possible, but discouraged
   • less reliable than id-based translation
   • prohibits changes to the original label

    XLIFF basics
    An XLIFF file can hold translations for one locale
    It contains one or more elements
    corresponding to a source
    Localizable data is stored in
    elements which contain a
    element to store the source text and a
    (non-mandatory) element to store the
    translated text

    i18n configuration
    Default locale can be set in Settings.yaml
    Locale fallback rules are configurable
    TYPO3:
    Flow:
    i18n:
    defaultLocale: de
    fallbackRule:
    strict: FALSE
    order: [lv, en]

    Tips & Tricks
    Split catalogs at logical points
    Try to use.a.clever.id.system
    Avoid hardcoded labels from the start
    To change "original" labels simply translate to
    "original" language

    Known issues
    L10n support in f:resource VH pending in review
    Fallback per label is missing, currently only done
    per catalog
    Overriding parts of catalogs is missing
    Model translation still missing
