Digital Twin Definition Language (DTDL) Model Editor

A general-purpose editor inspired by Azure IoT Central's model editor currently supporting DTDLv2.

NOTE: This project was generated with Angular CLI version 12.2.6 and uses Angular Material.

Currently Supported Features

• Basic support for:
  • Interfaces,
  • Properties,
  • Commands,
  • Telemetry,
  • Components,
  • Relationships (and Propertes)
• Basic validation
• Importing existing models
• Copy/Save models locally
• Editor settings
  • Set base DTMI

Near-Term Features

• Full DTDL validation
• Semantic Types
• Schema Definitions
• Command Request/Response payloads

Long-Term Features

• DTDLv3 (depends on Microsoft's timeline)
• Advanced Model Organization
• Model Graph View
• Basic model simulations

Known Issues

• Very little validation is in place
• Saving DTDL currently preserves NULL values (will fail validation)
• Base DTMI is inherited for all new capabilities
• Component and Relationship references are limited

Model Validation

Model validation will be performed using Microsoft's DTDL model validator:
