![]() ![]() These name/value pairs reflect the structure of the data. In most languages, this is realized as an vector, list, or sequence.Īn example JSON document is: //JSON ObjectĪs we can see, the JSON document consists of name/value pairs. An Array or Ordered list of values surrounded by square brackets.JSON is derived from JavaScript but as the name suggests, it is not limited to JavaScript only. In various languages, this is realized as an record, struct, dictionary, hash table, keyed list, or associative array. Protobuf is a binary data-interchange format developed by Google, whereas JSON is the human-readable data-interchange format. An Object surrounded by curly braces and containing multiple name/value pairs.Primarily, a valid JSON document can contain two structures: JSON DocumentĪ JSON document may contain text, curly braces, square brackets, colons, commas, double quotes, and maybe a few other characters. JSON’s Internet Assigned Numbers Authority (IANA) media (or MIME) type is application/json. ![]() The standard file type for storing a JSON document in the filesystem is. The new specifications remove inconsistencies with other specifications of JSON, repairs specification errors, and offer experience-based interoperability guidance. In March 2014, Tim Bray corrected errata with the original IETF 4627 in IETF RFC 7158 and RFC 7159. In 2013, Ecma International also standardized JSON under ECMA 404. JSON Specificationsĭouglas Crockford originally created JSON in 2001, and initially standardized it in 2006 under RFC 4627 through the IETF. In the early 2000s, JSON was initially specified by Douglas. It supports almost every kind of language, framework, and library. ![]() It is a language-independent data format. So while applications/libraries can parse the JSON documents – humans can also look at the data and derive the meaning from it.Īll modern programming languages (e.g., Java, JavaScript, Ruby, C#, PHP, Python, and Groovy) and application platforms provide excellent support for producing ( serializing) and consuming ( deserializing) JSON data. JSON is an acronym for JavaScript Object Notation, is an open standard format, which is lightweight and text-based, designed explicitly for human-readable data interchange. The good thing is that JSON is a human-readable as well as a machine-readable format. This data interchange can happen between two computer applications at different geographical locations or running within the same machine.
