Globalization

Introduction

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

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:

/base/global/

│   ├── frameworks          # Core code of the i18n framework
