Data structure of ThingModelJson - IoT Platform - Alibaba Cloud Documentation Center

When you call API operations that are related to Thing Specification Language (TSL) models, the request parameters or response parameters may contain the ThingModelJson parameter. The value of this parameter indicates the TSL data structure that is stored in IoT Platform. This TSL data structure is different from the original TSL data structure. All fields in the ThingModelJson parameter are sorted by key in alphabetical order.

For information about the limits of TSL features, see Limits.

Data structure

The data structure of a default TSL module is different from that of a custom TSL module.

Default TSL module

  "_ppk":{
       "description":"test",
       "version":"159244410****"
  }
  "events":[],
  "productKey":"al12345****",
  "properties":[],
  "services":[],
  "functionBlocks":[{
      "productKey":"al12345****",

_ppk	String	The information about the TSL model version. This parameter consists of the following fields: version: the version number of the current TSL model. This field is available only for published TSL models. description: the description of the current TSL model. This field is available only for published TSL models.
properties	List	The properties of the product to which the TSL model belongs. For more information about the data structure of the properties parameter, see Data structure of the properties parameter. In each property, you can use the extendConfig parameter to define the extended information about the TSL model. For more information, see Data structure of the extendConfig parameter. If no extended information needs to be defined, you do not need to specify the extendConfig parameter.
services	List	The services of the product to which the TSL model belongs. For more information about the data structure of the services parameter, see Data structure of the services parameter. In each service, you can use the extendConfig parameter to define the extended information about the TSL model. For more information, see Data structure of the extendConfig parameter. If no extended information needs to be defined, you do not need to specify the extendConfig parameter.
events	List	The events of the product to which the TSL model belongs. For more information about the data structure of the events parameter, see Data structure of the events parameter. In each event, you can use the extendConfig parameter to define the extended information about the TSL model. For more information, see Data structure of the extendConfig parameter.

Data structure of the extendConfig parameter

In each property, event, and service, you can use the extendConfig parameter to define the extended information about the TSL model. The extended information indicates the mapping between the connection protocol and the standard TSL model of the device.

Note The configCode parameter indicates the unique identifier that is generated by IoT Platform. The identifier is used to define the extended information about a TSL feature.

If Modbus, OPC UA, or a custom protocol is used as the gateway connection protocol of a device, you can define the extended information about the device. Different types of extended information have different data specifications.

Modbus type

If Modbus is used as the gateway connection protocol of a device, you can define the extended information only about the properties.

Note To fully demonstrate the data structure of the extendConfig parameter, the following example includes all parameters. However, the parameters may vary in actual scenarios. The following table describes these parameters.

Specify the ThingModelJson parameter

The section describes how to use the Visual Studio Code tool to specify the ThingModelJson parameter.

Visit Visual Studio Code official website to download and install the latest version of the Visual Studio Code tool.
Open Visual Studio Code, click the button in the lower left corner, and then select Settings.
On the User Settings tab, choose Extensions > JSON. Click Edit in settings.json under Schemas, and then enter and save the following content.
```
 "json.schemas": [{
        "fileMatch": ["/.json"],
        "url": "https://iotx-tsl.oss-ap-southeast-1.aliyuncs.com/schema.json"
}]
```
Then, you can specify the ThingModelJson parameter as prompted.
