+# Application Configuration File Overview (FA Model)
+
+
+Each application project must have configuration files in its code directory. These configuration files provide basic application information for OpenHarmony build tools, the operating system, and application markets.
+
+
+The application configuration file must contain the following information:
+
+
+- Basic information of the application, including the bundle name, vendor, and version number. Such information must be set under the **app** tag.
+
+- Component information of the application, including all abilities, device types, component types, and syntax types in use.
+
+- Device-specific information of the application. Such information affects the functioning of the application on the device.
+
+
+When developing an application in the Feature Ability (FA) model, you must declare the package structure of the application in the **config.json** file.
+
+
+## Configuration File Internal Structure
+
+The **config.json** file consists of three mandatory tags, namely, **app**, **deviceConfig**, and **module**.
+
+| Name| Description| Data Type| Initial Value Allowed|
+| -------- | -------- | -------- | -------- |
+| [app](app-structure.md) | Application-wide configuration. Different HAP files of an application must use the same **app** configuration. | Object| No|
+| [deviceConfig](deviceconfig-structure.md) | Device-specific configuration. | Object| No|
+| [module](module-structure.md) | HAP configuration. It is valid only for the current HAP file.| Object| No|

+# Application Configuration File Overview (Stage Model)
+
+
+Each application project must have configuration files in its code directory. These configuration files provide basic application information for build tools, operating systems, and application markets.
+
+
+In the code directory of an application project developed in stage model, there are two types of configuration files: one **app.json5** file and one or more **module.json5** files.
+
+
+The [app.json5](app-configuration-file.md) file contains the following contents:
+
+
+- Application-wide configuration, including the bundle name, developer, and version number.
+
+- Device-specific configuration.
+
+
+The [module.json5](module-configuration-file.md) file contains the following contents:
+
+
+- Basic module configuration, such as the name, type, description, and supported device types of the module.
+
+- Information about the [application components](../application-models/stage-model-development-overview.md), including the descriptions of the UIAbility and ExtensionAbility components.
+
+- Information about the permissions required during application running.

+# Application Installation and Uninstallation Process
+
+
+The OpenHarmony bundle manager service module provides APIs for installing, updating, and uninstalling applications. You can call these APIs when needed. After you release your application to the application market, users can install and uninstall it on their device.
+
+
+  **Figure 1** Process of installing and uninstalling an application 
+![hap-intall-uninstall](figures/hap-intall-uninstall.png)

en/application-dev/quick-start/application-package-overview.md

+# Application Package Overview
+
+
+A user application, also known as an application or app, runs on the operating system of devices and provides particular services for users. The software package corresponding to an application is called an application package.
+
+
+OpenHarmony provides an efficient management mechanism for application packages. By harnessing this mechanism, you can easily develop, install, query, update, and uninstall application packages.
+- To accelerate application deployment, you can use the integrated development tool provided by OpenHarmony to integrate executable code, resources, and third-party libraries into an OpenHarmony application package.
+
+- To distribute your application package by device type, you can specify the device types for distribution in the application package configuration file provided by OpenHarmony.
+
+- An application may provide a wide range of features. It is a good practice to divide and manage application features by module. OpenHarmony provides a multi-package management mechanism on an application-by-application basis. You can aggregate different application features into different packages to facilitate subsequent maintenance and expansion.
+
+- To allow an application to run across various chip platforms, such as x86, Arm, and other 32-bit or 64-bit platforms, OpenHarmony abstracts away the differences between chip platforms for application packages.
+
+- With a myriad of query APIs in OpenHarmony, you can quickly check the information about applications, including the application versions, names, components, and permissions.
+
+- To facilitate resource search and use, the bundle management service in OpenHarmony archives resources by type (media, native, string, internationalization, and more) in different directories and integrates resource index files.

+# Application Package Structure in FA Model
+
+
+To develop an application based on the [FA model](application-configuration-file-overview-fa.md), it is essential to understand the application package structure in this model.
+
+
+The difference between the application package structures in the FA model and stage model lies in where the internal files of a HAP file are stored. In the FA model, all the resource files, library files, and code files are stored in the **assets** folder, where the files are further organized.
+
+
+- **config.json** is an application configuration file, where the template code is automatically created by DevEco Studio. You can modify the configuration as required. For details about the fields in this file, see [Internal Structure of the app Tag](app-structure.md).
+
+- The **assets** folder is a collection of all the resource files, library files, and code files in a HAP file. It can be further organized into the **entry** folder and the **js** folder. The **entry** folder stores the **resources** folder and the **resources.index** file.
+
+- The **resources** folder stores resource files (such as strings and images) of the application.
+
+- The **resources.index** file provides a resource index table, which is generated by DevEco Studio invoking the specific SDK tool.
+
+- The **js** folder stores code files created after compilation.
+
+- The **pack.info** file describes the HAP attributes in the bundle, for example, **bundleName** and **versionCode** in **app** and **name**, **type**, and **abilities** in **module**. The file is automatically generated when DevEco Studio generates the bundle.

+# Application Package Structure in Stage Model
+
+
+To develop an application based on the [stage model](application-configuration-file-overview-stage.md), it is essential to understand the structure of the application package created after the application is built and packaged.
+
+
+- In development, an application contains one or more modules. You can [create modules](https://developer.harmonyos.com/en/docs/documentation/doc-guides-V3/ohos-adding-deleting-module-0000001218760594-V3) in the application project in [DevEco Studio](https://developer.harmonyos.com/en/develop/deveco-studio/). As a basic functional unit of an OpenHarmony application/service, a module contains source code, resource files, third-party libraries, and application/service configuration files, and can be built and run independently. Modules can be classified as Ability or Library. A module of the Ability type is built into a Harmony Ability Package (HAP) file in .hap format, and a module of the Library type is built into a [Harmony Ability Resources (HAR) file](har-structure.md) in .tgz format.
+  A module can contain one or more [UIAbility](../application-models/uiability-overview.md) components, as shown in the figure below.
+
+    **Figure 1** Relationship between modules and UIAbility components 
+  ![ability-and-module](figures/ability-and-module.png)
+
+  Unless otherwise specified, the modules described in this document refer to the modules of the Ability type.
+
+- As aforementioned, you can build an application into one or more HAP files. The HAP file is the basic unit for installing an application. It provides code, resources, third-party libraries, and a configuration file. HAP files can be classified as Entry or Feature.
+  - HAP of the entry type: main module of the application, whose **type** field is set to **"entry"** in the [module.json5](module-configuration-file.md) file. In an application, each type of device supports only one HAP of the entry type, which is typically used to implement the application's entry screen, entry icon, or headline feature.
+  - HAP of the feature type: dynamic feature module of the application, whose **type** field is set to **"feature"** in the [module.json5](module-configuration-file.md) file. Each application can contain zero, one, or more HAP files of the feature type, which are used to implement the application features. You can configure this type of HAP file to be downloaded and installed independently as required or to be downloaded and installed together with the HAP file of the entry type. For details, see **deliveryWithInstall** in [module.json5 Configuration File](module-configuration-file.md).
+
+- All the HAP files in an application are integrated into a bundle, and the bundle name is the unique identifier of the application. For details, see **bundleName** tag in [app.json5 Configuration File](app-configuration-file.md). Note that to release an application to the application market, all HAP files (that is, the bundle) contained in the application must be packed into an Application Package (App Pack) in .app format, which also contains the **pack.info** file that describes the attributes of the App Pack. The App Pack is distributed and installed on the cloud and on the device on a HAP-by-HAP basis.
+
+- The HAP file includes folders such as **ets**, **libs**, and **resources** and files such as **resources.index**, **module.json**, and **pack.info**.
+  - The **ets** folder stores bytecode files generated after application code build.
+  - The **libs** folder stores library files, which are .so binary files that contain third-party code on which the OpenHarmony application depends.
+  - The **resources** folder stores resource files (such as strings and images) of the application.
+  - The **resources.index** file provides a resource index table, which is generated when the application project is built in DevEco Studio.
+  - The **module.json** file is the configuration file indispensable in a HAP file. It consists of **module.json5** and **app.json5** in the project configuration.

+# Internal structure of deviceConfig Tag
+
+
+The **deviceConfig** tag contains device-specific configuration of the application, including attributes such as **default**, **tv**, **car**, and **wearable**. The **default** configuration applies to all types of devices. You need to declare the peculiar configuration of a specific device type in the associated sub-tag of this type.
+
+###   Table 1 Internal Structure of the deviceConfig Tag
+
+| Name| Description| Data Type| Initial Value Allowed|
+| -------- | -------- | -------- | -------- |
+| default | Application configuration specific to the OpenHarmony device that provides full access to system capabilities.| Object| Yes (initial value: left empty)|

+
+####   Table 2 Internal Structure of the deviceConfig Attributes
+
+| Name| Description| Data Type| Initial Value Allowed|
+| -------- | -------- | -------- | -------- |
+| process | Name of the process running the application or ability. If the **process** attribute is configured in the **deviceConfig** tag, all abilities of the application run in this process. You can set the **process** attribute for a specific ability in the **abilities** attribute, so that the ability can run in the particular process. The value can contain a maximum of 31 characters.| String| Yes (initial value: left empty)|
+| keepAlive | Whether the application is always running. This attribute applies only to system applications and does not take effect for third-party applications. The value **true** means that the application will start during the OS startup and keep alive. If the application process exits, the OS will restart it.| Boolean| Yes (initial value: **false**)|
+| supportBackup | Whether the application supports backup and restoration. The value **false** means that the application does not support backup or restoration.| Boolean| Yes (initial value: **false**)|
+| compressNativeLibs | Whether the **libs** libraries are packaged in the HAP file after being compressed. The value **false** means that the **libs** libraries are stored without being compressed and will be directly loaded during the installation of the HAP file.| Boolean| Yes (initial value: **false**)|
+| network | Network security configuration. You can customize the network security settings of the application in the security statement of the configuration file without modifying the application code.| Object| Yes (initial value: left empty)|
+

+
+####   Table 5 Internal Structure of the domainSettings Attribute
+
+| Name| Description| Data Type| Initial Value Allowed|
+| -------- | -------- | -------- | -------- |
+| cleartextPermitted | Whether plaintext traffic can be transmitted in the custom network domain. If both **cleartextTraffic** and **security** are declared, whether plaintext traffic can be transmitted in the custom network domain is determined by the **cleartextPermitted** attribute. **true**: Plaintext traffic can be transmitted. **false**: Plaintext traffic cannot be transmitted.| Boolean| Yes (initial value: left empty)|
+| domains | Domain name. This attribute consists of two sub-attributes: **subdomains** and **name**. **subdomains** (boolean): specifies whether the domain name contains subdomains. If this sub-attribute is set to **true**, the domain naming convention applies to all related domains and subdomains (including the lower-level domains of the subdomains). Otherwise, the convention applies only to exact matches. **name** (string): indicates the domain name.| Object array| Yes (initial value: left empty)|

+# HAR File Structure
+
+
+The Harmony Ability Resources (HAR) file enables code to be shared among multiple modules or projects. Unlike a Harmony Ability Package (HAP) file, a HAR file cannot be independently installed on a device. Instead, it can only be referenced as the dependency of an application module.
+
+
+A HAR file is the build product of a [module](https://developer.harmonyos.com/en/docs/documentation/doc-guides-V3/ohos-adding-deleting-module-0000001218760594-V3) of the Library type in a DevEco Studio project.
+
+
+The HAR file reuses the standard [npm package](https://developer.harmonyos.com/en/docs/documentation/doc-guides/ohos-development-npm-package-0000001222578434) release mode and is packed into a .tar package with the file name extension .tgz. The packed HAR file contains the source code, resource files, and the **module.json** file (in stage model) or **config.json** file (in FA model).

en/application-dev/quick-start/multi-hap-build-view.md

+# Multi-HAP Build View
+
+
+DevEco Studio allows you to develop and build multiple HAP files in one application project, as shown below.
+
+
+  **Figure 1** Multi-HAP build view 
+![hap-multi-view](figures/hap-multi-view.png)
+
+
+1. Development view in DevEco Studio
+   - AppScope folder
+      - [app.json5](app-configuration-file.md): application-wide configuration, such as the application bundle name, version number, application icon, application name, and dependent SDK version number.
+      - **resources** folder: stores application icon resources and application name string resources.
+
+         **NOTE**
+         - The folder is automatically generated by DevEco Studio and its name cannot be changed.
+         - The file names in the **AppScope** folder cannot be the same as those in the entry- or feature-type module directories. Otherwise, DevEco Studio reports an error.
+   - Entry- or feature-type module directories (the names are customizable)
+      - You implement service logic of your application in these module directories. In this example, the module folders are **entry.hap** and **feature.hap**.
+      - **resources** directory: stores the resources used by the module.
+      - **ets** folder: stores the service logic.
+      - [module.json5](module-configuration-file.md): module configuration, such as the module name, entry code path of the module, and component information.
+
+2. View after build and packaging
+   - After a module is built, a HAP file for deployment is generated. Each module corresponds to a HAP file.
+   - The **module.json** file in the HAP file is composed of the **app.json5** and **module.json5** files in the development view.
+   - All HAP files are finally built into an Application Package (App Pack) in .app format for release to the application market.

en/application-dev/quick-start/multi-hap-objective.md

+# Multi-HAP Design Objectives
+
+
+- Modular management: A well-designed application is generally managed in a modular manner, where modules are loosely coupled. In light of this, the multi-HAP mechanism is designed, allowing you to divide services into multiple modules and store each module in an independent HAP file. For example, If you are developing a payment application and its home screen consists of multiple modules, such as the scan, pay, messaging, and finance modules, you can implement the logic of the home screen for managing other modules in the entry-type HAP file, and implement specific modules in feature-type HAP files. The feature-type HAP files are independent. You can develop and test each of them separately, and then integrate them with the entry-type HAP file.
+
+- Flexible deployment: You can combine multiple HAP files and deploy them on different devices. Assume that an application contains one entry-type HAP file (**Entry.hap**) and two feature-type HAP files (**Feature1.hap** and **Feature2.hap**). The **Entry.hap** file can be deployed on device A and device B, the **Feature1.hap** file can be deployed only on device A, and the **Feature2.hap** can be deployed only on device B. In this way, you can easily combine the **Entry.hap** and **Feature1.hap** files and deploy them on device A, and combine the **Entry.hap** and **Feature2.hap** files and deploy them on device B.
+
+- On-demand loading: You can load modules only when they are needed, reducing the package size. Specifically, you can configure some HAP files of an application to be loaded on demand. For example, if some features are not used during application startup, you can configure them to be loaded only when they are needed, rather than being loaded at startup. This can reduce the size of the application package to some extent.
+
+- Easier resource sharing: The resources (including public resource files and public pages) and shared objects (.so library files) required by multiple HAP files can be stored in an independent HAP file. In this way, other HAP files can obtain the resources and files by accessing the HAP, which reduces the size of the application package to some extent.

en/application-dev/quick-start/multi-hap-principles.md

+# Multi-HAP Operation Mechanism and Data Communication Modes
+
+
+The multi-HAP mechanism is used to facilitate modular management for developers. There is no one-to-one mapping between the HAP and the running process of the application. The detailed running mechanism is as follows:
+
+
+- By default, all UIAbility, ServiceExtensionAbility, and DataShareExtensionAbility components of an application (with the same bundle name) run in the same independent process, and other ExtensionAbility components of the same type run in separate processes.
+
+- The HAP file supports the process configuration through the **process** tag in the **module.json5** (stage model) or **config.json** (FA model) file. This feature is supported only by system applications. If **process** is configured for an HAP file, all components of the HAP file run in an independent process. Multiple HAP files can be configured with the same process, in which case the HAP files run in the same process. For details about the process configuration, see [module.json5 Configuration File](module-configuration-file.md).
+
+- When an application is running, the resources and code of the corresponding HAP file are loaded only when the UIAbility component in the same process is started.
+
+
+Based on the preceding mechanism, the multi-HAP data communication modes are as follows:
+
+
+- For details about data communication in the same process, see [Thread Model (Stage Model)](../application-models/thread-model-stage.md).
+
+- For details about cross-process data communication, see [Process Model (Stage Model)](../application-models/process-model-stage.md).
+
+- If multiple HAPs run in the same process, the communication mode between the components of multiple HAP files is the same as that between the components of the same HAP file.

+# Multi-HAP Development, Debugging, Release, and Deployment Process
+
+Below is the process of developing, debugging, releasing, and deploying multiple HAP files.
+
+**Figure 1** Process of developing, debugging, releasing, and deploying multiple HAP files
+![hap-release](figures/hap-release.png)
+
+## Development
+You can use [DevEco Studio](https://developer.harmonyos.com/en/develop/deveco-studio) to create multiple modules based on service requirements and develop services in independent modules.
+
+## Debugging
+You can use DevEco Studio to build code into one or more HAP files. Then, you can debug the HAP files.
+* Using DevEco Studio for debugging
+
+   Follow the instructions in [Debugging Configuration](https://developer.harmonyos.com/en/docs/documentation/doc-guides/ohos-debugging-and-running-0000001263040487#section10491183521520).
+
+* Using [hdc_std](../../device-dev/subsystems/subsys-toolchain-hdc-guide.md) for debugging
+
+    You can obtain the hdc_std tool from the **toolchains** directory of the SDK. When using this tool to install an HAP file, the HAP file path is the one on the operating platform. In this example, the Windows operating platform is used. The command reference is as follows:
+    ```
+    // Installation and update: Multiple file paths can be specified.
+    hdc_std install C:\entry.hap C:\feature.hap
+    // The execution result is as follows:
+    install bundle successfully.
+    // Uninstall
+    hdc_std uninstall com.example.myapplication
+    // The execution result is as follows:
+    uninstall bundle successfully.
+    ```
+
+* Using Bundle Manager (bm) for debugging
+
+    When using bm to install or update an HAP file, the HAP file path is the one on the real device. The command reference is as follows:
+    ```
+    // Installation and update: Multiple file paths can be specified.
+    bm install -p /data/app/entry.hap /data/app/    feature.hap
+    // The execution result is as follows:
+    install bundle successfully.
+    // Uninstall
+    bm uninstall -n com.example.myapplication
+    // The execution result is as follows:
+    uninstall bundle successfully.
+    ```
+## Release
+When your application package meets the release requirements, you can package and build it into an App Pack and release it to the application market on the cloud. The application market verifies the signature of the App Pack. If the signature verification is successful, the application market obtains the HAP files from the App Pack, signs them, and distributes the signed HAP files.
+
+## Deployment
+The application market on the cloud distributes the applications to application market clients. These applications can contain one or more HAP files. After the user selects an application to download, the application market downloads all the HAP files contained in this application.
+
+## Installation on a Device
+After the download is complete, the application market client calls the installation API of the bundle manager service in the system to install the downloaded HAP files. The bundle manager service deploys HAP files by application in the specified directory to complete the application installation.

en/application-dev/quick-start/multi-hap-rules.md

+# Multi-HAP Usage Rules
+
+
+- The App Pack cannot be directly installed on the device. It is only a unit that is released to AppGallery.
+
+- All HAP files in the App Pack must share the same **bundleName** value in the configuration files.
+
+- All HAP files in the App Pack must share the same **versionCode** value in the configuration files.
+
+- In an application, each type of device supports only one HAP of the entry type. Each application can contain zero, one, or more HAP files of the feature type.
+
+- Each HAP file in the App Pack must have **moduleName** configured. The **moduleName** value corresponding to all HAP files of the same device type must be unique.
+
+- The signing certificates of all HAP files in the same application must be the same. Applications are released to the application market in the form of App Pack after being signed. Before distribution, the application market splits an App Pack into HAP files and resigns them to ensure the consistency of all HAP file signing certificates. Before installing HAP files on a device through the CLI or DevEco Studio for debugging, you must ensure that their signing certificates are the same. Otherwise, the installation will fail.

+### Application Model
 
-### Ability
+The application model is the abstraction of capabilities required by OpenHarmony applications. It provides necessary components and running mechanisms for applications. With application models, you can develop applications based on a unified set of models, making application development simpler and more efficient. For details, see [Elements of the Application Model](../application-models/application-model-composition.md).
 
-An ability is the abstraction of a functionality that an application can provide. An application may provide various capabilities, and so it can have multiple abilities. These abilities can be deployed together or independently from each other.
+Along its evolution, OpenHarmony has provided two application models:
 
-The ability framework model has two forms:
+- Feature Ability (FA) model. This model is supported by OpenHarmony API version 7 and 8. It is no longer recommended. For details about development based on the FA model, see [FA Model Development Overview](../application-models/fa-model-development-overview.md).
+- Stage model. This model is supported since OpenHarmony API version 9. It is recommended and will evolve for a long time. In this model, classes such as **AbilityStage** and **WindowStage** are provided as the stage of application components and windows. That's why it is named stage model. For details about development based on the stage model, see [Stage Model Development Overview](../application-models/fa-model-development-overview.md).
 
-- **FA model**: applies to application development using API version 8 and earlier versions. For details, see [FA Model Overview](../ability/fa-brief.md).
+For details about the differences between the FA model and stage model, see [Interpretation of the Application Model](../application-models/application-model-description.md).
 
-- **Stage model**: introduced since API version 9. For details, see [Stage Model Overview](../ability/stage-brief.md).
-
-The project directory structure of the FA model is different from that of the stage model. The stage model only works with the ArkTS programming language.
-
-For details about the differences between the FA model and stage model, see [Ability Framework Overview](../ability/ability-brief.md).
