The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
This specification and [RFC 8259] both provide specifications of the JSON grammar but do so using different formalisms. The intent is that both specifications define the same syntactic language. If a difference is found between them, Ecma International and the IETF will work together to update both documents. If an error is found with either document, the other should be examined to see if it has a similar error, and fixed if possible. If either document is changed in the future, Ecma International and the IETF will work together to ensure that the two documents stay aligned through the change.RFC 8259, also defines various semantic restrictions on the use of the JSON syntax. Those restrictions are not normative for this specification.
An object structure is represented as a pair of curly bracket tokens surrounding zero or more name/value pairs. A name is a string. A single colon token follows each name, separating the name from the value. A single comma token separates a value from a following name. The JSON syntax does not impose any restrictions on the strings used as names, does not require that name strings be unique,and does not assign any significance to the ordering of name/value pairs. These are all semantic considerations that may be defined by JSON processors or in specifications defining specific uses of JSON for data interchange.
An array structure is a pair of square bracket tokens surrounding zero or more values. The values are separated by commas. The JSON syntax does not define any specific meaning to the ordering of the values. However, the JSON array structure is often used in situations where there is some semantics to the ordering.ISO IEC 21778 pdf free download.
