API > API/Developer > API/Developer/Localization

High-level access to the non-compiled localization resources (manifests and archives) in a way that abstracts some of their quirks. Each instance gives access to a single localization target consisting of a single manifest and several archives (a native archive, and one for each foreign culture).
