Input Data

Input Data elements denote information used as an input by one or more Decisions. When invoking a DMN model, you must provide values for all required Input Data.

Semantics

  • Role: Represents an external fact or parameter.
  • Variable: Defines a variable name (used in FEEL expressions) and a data type.

Implementation Details

In the JSON payload when conceptualizing a request to the engine:

{
"Weather": "Sunny",
"Age": 25
}

If your model has an Input Data node named Weather, the engine maps the value "Sunny" to it.

tip

Input Data names must differ from Decision names to avoid variable shadowing.
