Validation logic

The validation logic of a validation rule expresses the condition that is checked by the validation rule. In a basic validation script, it is contained directly in the rule. In an advanced validation script, it is contained in the then-section. More information: Validation scripts.

Structure

Each line typically consists of:

1. A validation function. More info: Validation functions.
2. An attribute from the given-section, an asset property or a constant value.
3. A message for when assets do not meet the condition of the validation function.
4. Other syntactic elements:
   
   • Aggregate functions
   • Validation functions
   • Multi-line boolean expressions
   • Collections in validation script
   • Closures

What's next?

If an asset does not meet the validation logic, the outcome of the rule is invalid.
If the asset meets the validation logic, the outcome of the rule is valid.

	isNotEmpty(attributes['Definition'], 
        message: "The asset ${name} in domain ${vocabulary.name} \
                  must have at least one definition")
}
