JSON Schema - Constant values (original) (raw)
New in draft 6
The const keyword is used to restrict a value to a single value.
For example, if you only support shipping to the United States for export reasons:
schema
{ "properties": { "country": { "const": "United States of America" } }}
data
{ "country": "United States of America" }
compliant to schema
data
{ "country": "Canada" }
not compliant to schema
