 # Data Ability Development
+
 ## When to Use
+
 A Data ability helps applications manage access to data stored by themselves and other applications. It also provides APIs for sharing data with other applications either on the same device or across devices.
 
 Data ability providers can customize data access-related APIs such as data inserting, deleting, updating, and querying, as well as file opening, and share data with other applications through these open APIs.
 
+## URI Introduction
+
+A Uniform Resource Identifier (URI) is used to identify a specific data item, such as a table in the database or a file on the disk. URIs used in OpenHarmony comply with the commonly used URI standard. A URI consists of the components:
+
+![fa-dataability-uri](figures/fa-dataability-uri.png)
+
+- **scheme**: name of the scheme used by the Data ability. The value is fixed at **dataability**.
+- **authority**: device ID. To access data on a remote device, set this component to the ID of the remote device. To access data on the local device, leave this component empty.
+- **path**: location of the specific resource to access.
+- **query**: query parameters.
+- **fragment**: subordinate resources to access.
+
+Example URIs:
+
+- Cross-device communication: **dataability://***device_id***/***com.domainname.dataability.persondata***/***person***/***10*
+- Local-device communication: **dataability:///***com.domainname.dataability.persondata***/***person***/***10*
+
+
+> **NOTE**
+>
+> In the case of local-device communication, **device_id** is empty, and therefore, there are three slashes (/) after **dataability:**.

 # Preferences Development
 
+> **NOTE**
+>
+> This feature is supported since API Version 9. For the versions earlier than API Version 9, use [Lightweight Storage](../reference/apis/js-apis-data-storage.md) APIs.
+
 ## When to Use
 
 Preferences are ideal for storing data frequently used by applications, but not for storing a large amount of data or data with frequent changes. The application data is persistently stored on a device in the form of files. Note that the instance accessed by an application contains all data of the file. The data is always loaded to the memory of the device until the application removes it from the memory. The application can perform data operations using the **Preferences** APIs.
 
 ## Available APIs
 
-Preferences provide capabilities for processing data in the form of key-value (KV) pairs and support data persistence, modification, and query. In KV pairs, keys are of the string type, and values can be of the number, string, or Boolean type.

Using the APIs provided by sensors, you can query sensors on your device, subscribe to sensor data, customize algorithms based on sensor data, and develop various sensor-based applications, such as compass, motion-controlled games, and fitness and health applications.

 A sensor is a device to detect events or changes in an environment and send messages about the events or changes to another device (for example, a CPU). Generally, a sensor is composed of sensitive components and conversion components. Sensors are the cornerstone of the IoT. A unified sensor management framework is required to achieve data sensing at a low latency and low power consumption, thereby keeping up with requirements of "1+8+N" products or business in the Seamless AI Life Strategy. The sensor list is as follows:

+# Audio Interruption Mode Development
+
+## When to Use
+The audio interruption mode is used to control the playback of multiple audio streams.<br>
+Audio applications can set the audio interruption mode to independent or shared under **AudioRenderer**.<br>
+In shared mode, multiple audio streams share one session ID. In independent mode, each audio stream has an independent session ID.
+
+### Asynchronous Operations
+
+To prevent the UI thread from being blocked, most **AudioRenderer** calls are asynchronous. Each API provides the callback and promise functions. The following examples use the promise functions.
+
+## How to Develop
+
+For details about the APIs, see [AudioRenderer in Audio Management](../reference/apis/js-apis-audio.md#audiorenderer8).
+
+
+1. Use **createAudioRenderer()** to create an **AudioRenderer** instance.<br>
+   Set parameters of the **AudioRenderer** instance in **audioRendererOptions**.<br>
+   This instance is used to render audio, control and obtain the rendering status, and register a callback for notification.<br>
+
+   ```js
+   import audio from '@ohos.multimedia.audio';
+
+    var audioStreamInfo = {
+        samplingRate: audio.AudioSamplingRate.SAMPLE_RATE_44100,
+        channels: audio.AudioChannel.CHANNEL_1,
+        sampleFormat: audio.AudioSampleFormat.SAMPLE_FORMAT_S16LE,
+        encodingType: audio.AudioEncodingType.ENCODING_TYPE_RAW
+    }
+   
+    var audioRendererInfo = {
+        content: audio.ContentType.CONTENT_TYPE_SPEECH,
+        usage: audio.StreamUsage.STREAM_USAGE_VOICE_COMMUNICATION,
+        rendererFlags: 1
+    }
+   
+    var audioRendererOptions = {
+        streamInfo: audioStreamInfo,
+        rendererInfo: audioRendererInfo
+    }
+   
+    let audioRenderer = await audio.createAudioRenderer(audioRendererOptions);
+   ```
+
+2. Set the audio interruption mode.
+   
+   After the **AudioRenderer** instance is initialized, you can set the audio interruption mode.<br>
+
+   ```js
+    var mode_ = audio.InterruptMode.SHARE_MODE;
+    await this.audioRenderer.setInterruptMode(mode_).then(()=>{
+      console.log('[JSAR] [SetInterruptMode] Setting: '+ (mode_ == 0? " share mode":"independent mode") + "success");
+    });
+   ```
