JSON Schema - Enumerated and constant values (original) (raw)

The enum and const keywords contribute to data validation by defining limits on the values a property can hold.

• Define a set of values. Use the enum keyword to specify a finite set of acceptable values for a property. This ensures that only predefined options are valid.
• Define a fixed, single value. Use the const keyword to force a property to have a single, fixed value. This keyword is more restrictive than enum.

Learn more about how to use these keywords with the following resources:

• Enumerated values
• Constant values

By effectively utilizing these keywords, you can significantly enhance the reliability and accuracy of your JSON data.
