Overview

The Digital Twin Definition Language (DTDL) is a language for describing models for Plug and Play devices, device digital twins, and logical digital twins. Broadly, modeling enables IoT solutions to provision, use, and configure digital twins of all kinds from multiple sources in a single solution. Using DTDL to describe any digital twin’s abilities enables the IoT platform and IoT solutions to leverage the semantics of each digital twin.

With the DTDL extension for Visual Studio Code , you can read and write documents using DTDL more efficiently taking full advantage of the following key features:

• Create interfaces from the command palette with predefined or customized templates.
• Intellisense to help you with the language syntax (including auto-completion).
• Use predefined code snippets to develop DTDL efficiently.
• Syntax validation.

Get Started

Create Interface

You could use the command palette to create interface from predefined or customized templates.

• In Visual Studio Code, select View > Command Palette to open the VS Code command palette.
• In the command palette, enter and run the command DTDL: Create Interface.
• Follow the instruction to assign the interface name.
• If there are multiple templates existing, choose a template you need. Otherwise, the extension will the basic template as default.
• A JSON file will be created in the current folder. The file name is based on the interface name you assigned.
• The @id is the path component of the Digital Twin Model Identifier (DTMI). You should modify the @id following the DTMI rule to uniquely identify the device model.

Intellisense and Syntax validation

This extension could help you with the language syntax (including auto-completion) and also validate the syntax with DTDL.

Use Predefined Code Snippets

Besides the basic auto completion, this extension also provides some predefined code snippets to help you develop DTDL efficiently.

Create Your Own Template

Prepare your template file

You could use any DTDL file as a template to develop efficiently. Meanwhile, you could also use these predefined tags to make your template more flexible.

• {modelId}: The extention will replace this tag with dtmi:com:example:interface_name;1 when creating a new DTDL from a template. For example, if you assigned the interface name as "test", the result will be dtmi:com:example:test;1.
• {modelName}: The extension will replace this tag with the interface name when creating a new DTDL from a template.

Import your template file

• Go to [extension installation location]/vsciot-vscode.vscode-dtdl-[extension release version]/templates
• Store your template into this folder as a JSON file. Keep the file name short and meaningful, because the extension will use the file name as template name.

Create Your Own Code Snippets

If you would like to create customized code snippets for VS Code, you could follow Snippets in Visual Studio Code

Contribute Your Templates and Code Snippets to the Community

You could also contribute your templates and code snippets to the DTDL repository.

• Uploading the new templates to templates folder.
• Modifying and adding new code snippets to snippets/snippets.json file.

Once the pull request is approved, your templates and code snippets will be released with next release of DTDL extension.

Commands

Trouble Shooting

Error when creating the interface

As default, the extension will get the available templates from [extension installation location]/vsciot-vscode.vscode-dtdl-[extension release version]/templates. But if you delete this folder or all templates files in this folder, you will have an error when creating the interface. In order to fix this issue, you could copy the templates from DTDL repository to your local templates folder manually.
