The Globalization subsystem provides the multi-language and multi-cultural capabilities for global use, including: 6 7- **Resource management** 8 9 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. 10 11- **Internationalization \(i18n\)** 12 13 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. 14 15 16## Architecture<a name="section1558604311012"></a> 17 18**Figure 1** Architecture of the globalization subsystem<a name="fig1687592425010"></a> 19 20 21 22 23## Directory Structure<a name="section161941989596"></a> 24 25The source code of the Globalization subsystem is stored in the **/base/global** directory. 26 27The directory structure of the Globalization subsystem for the mini and small systems is as follows: 28 29``` 30/base/global/ 31├── i18n_lite # Code repository for the i18n framework 32│ ├── frameworks # Core code of the i18n framework 33│ │ ├── i18n # i18n module 34│ │ │ ├── include # Header files 35│ │ │ ├── src # Implementation code 36│ │ │ └── test # Test code 37│ ├── interfaces # APIs 38│ │ ├── kits # Application APIs 39│ │ │ ├── i18n # C/C++ i18n APIs 40│ │ │ └── js # C/C++ support for JavaScript APIs 41├── resmgr_lite # Code repository for the Resmgr framework 42│ ├── frameworks # Core code of the Resmgr framework 43│ │ ├── resmgr # Resource parsing code 44│ │ │ ├── include # Header files 45│ │ │ └── src # Implementation code 46│ ├── interfaces # APIs 47│ │ └── innerkits # APIs for internal subsystems 48``` 49 50The directory structure of the Globalization subsystem for the standard system is as follows: 51 52``` 53/base/global 54├── i18n # Code repository for the i18n framework 55│ ├── frameworks # Core code of the i18n framework 56│ ├── interfaces # APIs 57│ │ ├── js # JavaScript APIs 58│ │ └── native # Native APIs 59├── resmgr_standard # Code repository for the Resmgr module 60│ ├── frameworks # Core code 61│ │ ├── resmgr # Resource parsing code 62│ │ │ ├── include # Header files 63│ │ │ ├── src # Implementation code 64│ │ │ └── test # Test code 65│ ├── interfaces # APIs 66│ │ ├── innerkits # APIs for internal subsystems 67│ │ └── js # JavaScript APIs 68``` 69 70## Repositories Involved<a name="section1371113476307"></a> 71 72**Globalization subsystem** 73 74[global\_i18n\_lite](https://gitee.com/openharmony/global_i18n_lite) 75 76[global\_i18n](https://gitee.com/openharmony/global_i18n) 77 78[global\_resmgr\_lite](https://gitee.com/openharmony/global_resmgr_lite) 79 80[global\_resmgr\_standard](https://gitee.com/openharmony/global_resmgr_standard) 81 82
