A language bundle is a collection of localizable and translatable fields and language-specific contents in a given language that can be added to an object in the LMS (for example, a course, catalog, or news article). Different LMS objects can have their own set of localizable fields. All localizable objects have a primary language, which is the default language used. You can manage the language bundles for each object independently.
For more information about multi-language support for the LMS, please refer to the EN600 Multi-language Content Support Implementation Guide.
