An L10N Layer Cake

1
An L10N Layer Cake

• Follows the Semantic Web Layer Cake
• aka W3C Semantic Stack
• aka Enabling Standards Layer Cake
• A simple model to illustrate, at a glance,
  dependencies and relationships of relevant
  standards to localization.
• The layer cake has evolved over the years and is
  still a popular model, it is widely understood.
• Not intended to be a strict or precise model,
  illustrative only.

Notes

• SCIM is Unix only (?)
• Feel like a layer is missing
• Maybe add TRs to the UCD Block

Notes

• This layer cake is meant to show association of
  applicable standards, but others could be
  developed for simple l10n components
• ICU could break down into component layers like
  calendars, collation, transliteration, etc.
