Common JSON Rules In JSON, Boolean values can be text or JSON Boolean constants. In both cases, values are case-insensitive. The following two members are considered identical: "AutoTables": "true" "AutoTables": TRUE Numeric values can be provided as text literals or numeric constants. The following two members are considered identical: "Size": 70392 "Size": "70392" Null or empty values can be provided using either the JSON keyword NULL (case-insensitive) or an empty string. For example: "Occupation": null "Occupation": "" In JSON output messages, Doradus always quotes literal values, including Booleans and numbers. Null values are always represented by a pair of empty quotes.
