Transform By JDM - Bringits

The Transform By JDM command (Command Type: 1017) transforms the current data into a new object by applying JDM (JSON Decision Model) mapping rules. It supports optional state usage during transformation.

Overview

The Transform By JDM command provides functionality for:

Applying complex mapping rules defined in a JDM JSON object
Transforming input data into a completely different output structure
Optionally leveraging state from the execution context during transformation

Command Type

Command Type ID: 1017

Parameters

Parameter	Type	Description	Required
jdm	object	The JSON object containing the JDM mapping rules for transforming the data	Yes
timeout	number	The timeout for the command in milliseconds	Yes
useState	boolean	If `true`, uses the current execution state during transformation. Defaults to `false`	No

Usage Examples

Basic Field Mapping

{
  "command": "transform-by-jdm",
  "params": {
    "jdm": {
      "nodes": [],
      "edges": []
    },
    "timeout": 5000
  }
}

Transform with State

{
  "command": "transform-by-jdm",
  "params": {
    "jdm": {
      "nodes": [],
      "edges": []
    },
    "timeout": 10000,
    "useState": true
  }
}

JDM Structure

The jdm object follows the gorules/zen JSON Decision Model format — a graph of nodes and edges describing transformation logic. Refer to the gorules/zen documentation for the full JDM specification.

Common Use Cases

Complex Transformations: Apply non-trivial multi-field transformation logic in one step
Rule-Based Mapping: Use decision model rules to conditionally map data
State-Aware Transforms: Include execution state context in the transformation

JSONata - Expression-based transformation
Zen Parse Expression - Evaluate Zen expressions
Object Mapper - Simpler field-level mapping
