1617 JSON Data Interchange Format JavaScript Object Notation (JSON) is an open standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs. It is used for asynchronous browser/server communication (AJAJ). While it is originally derived from JavaScript scripting language, JSON is language independent while using conventions that match with the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and others. 1 Digital Preservation Department / The National Archives 11 Dec 2015 11 Dec 2015 application/json MIME fmt/817 PUID json File extension Has lower priority than 2129 Tweet JSON
