Overview

​

Metadata to Label Model

This model converts document metadata properties into document labels based on configurable rules. It examines metadata values, evaluates conditions, and applies labels when conditions are met.

​

How It Works

1. The model examines the document’s metadata for specified properties
2. For each property found, it evaluates a condition using the property’s value
3. If the condition evaluates to true, it applies the corresponding label to the document

​

Options Configuration

Each property configuration requires:

• name: The metadata property name to check
• expression: A condition using value as the property value
• label: The label to apply when the condition is true

​

Expression Syntax

The expression field supports simple conditional expressions with the following capabilities:

• Basic comparisons: ==, !=, >, <, >=, <=
• Logical operators: and, or, not
• String checks: value == 'text', 'text' in value
• Case-insensitive checks: value.lower() == 'text'
• Existence checks: value is not None

The keyword value always represents the current metadata property’s value.

​

Example Configurations

​

Flag Unpublishable Documents

properties:
  - name: ShouldPublish
    expression: value == 'False' or value == 'false'
    label: DO_NOT_PUBLISH

​

Label Documents by Department

properties:
  - name: Department
    expression: value == 'Finance'
    label: FINANCE
  - name: Department
    expression: value == 'HR'
    label: HUMAN_RESOURCES

​

Flag Priority Documents

properties:
  - name: Priority
    expression: value > 8
    label: HIGH_PRIORITY

​

Use Cases

This model is particularly useful for:

• Converting external system metadata into Kodexa document labels
• Creating document filtering and routing rules based on metadata
• Implementing conditional workflows based on document properties
• Integrating with systems that use metadata rather than labels
• Simplifying document classification based on existing metadata

Since the model uses simple evaluation of expressions, it provides a lightweight way to implement business rules without complex coding.

name: dont_publish property: ShouldPublishXml expression: value == ‘False’ or value == ‘false’
