## Introduction<a name="section11660541593"></a>

If OpenHarmony devices and applications need to be used globally, they must meet the requirements of users in different regions on languages and cultures. The Globalization subsystem provides the multi-language and multi-cultural capabilities for global use, including:

-   **Resource management**

    The subsystem loads, parses, and initializes system and application resources based on device types and system configurations, and provides APIs for obtaining resources such as character strings and media files.

-   **Internationalization \(i18n\)**

    The subsystem provides the bottom-layer resource backtracking capabilities, with a wide array of i18n APIs for implementing functions such as date/time formatting, number formatting, phone number formatting, and singular-plural formatting.

## Directory Structure<a name="section161941989596"></a>

The source code of the Globalization subsystem is stored in the  **/base/global**  directory.

The directory structure of the Globalization subsystem for the mini and small systems is as follows:

```

The directory structure of the Globalization subsystem for the standard system is as follows:
