standard =The JSON Markup Language (JsonML) is a lightweight markup language which is used as a mapping between XML and JSON (JavaScript Object Notation). Using JsonML one may convert an XML document or fragment into a JSON data structure for ease of use within JavaScript environments such as a web browser. JsonML allows manipulation of XML data without the need or overhead of an XML parser.

JsonML has greatest applicability in Ajax web applications. It may be used to transport XHTML down to the client where it can be deterministically reconstructed into DOM Elements. Strategies such as progressive enhancement may be employed during construction to bind dynamic behaviors to the otherwise static elements.

There are two forms of JsonML: The Array Form and the Object Form.

JsonML Array Form uses JSON Arrays to represent XML elements, JSON Objects to represent attributes, and JSON Strings to represent Text nodes. Conversion from XML to JsonML is fully reversible. XML Namespaces are handled by prepending the element name with the namespace prefix (e.g. <myns:myElement/> becomes ["myns:myElement"] ).

JsonML Array Form representation of a person record:

["person", {"created":"2006-11-11T19:23", "modified":"2006-12-31T23:59"}, ["firstName", "Robert"] , ["lastName", "Smith"] , ["address", {"type":"home"}, ["street", "12345 Sixth Ave"] , ["city", "Anytown"] , ["state", "CA"] , ["postalCode", "98765-4321"] ]

JsonML Object Form uses JSON Objects to represent XML elements and their attributes, and JSON Arrays to represent child node lists.

JsonML Object Form representation of a person record:

{"tagName": "person", "created": "2006-11-11T19:23", "modified": "2006-12-31T23:59"}, "childNodes": [ {"tagName": "firstName", "childNodes" : ["Robert"] }, {"tagName": "lastName", "childNodes" : ["Smith"] }, {"tagName": "address", "type":"home", "childNodes" : [ {"tagName": "street", "childNodes" : ["12345 Sixth Ave"] }, {"tagName": "city", "childNodes" : ["Anytown"] }, {"tagName": "state", "childNodes" : ["CA"] }, {"tagName": "postalCode", "childNodes" : ["98765-4321"] }, ] }]

The JSON Data Transformation produces a more compact representation but loses some of the document structural information.

{"person": { "address": { "city": "Anytown", "postalCode": "98765-4321", "state": "CA", "street": "12345 Sixth Ave", "type": "home" }, "created": "2006-11-11T19:23", "firstName": "Robert", "lastName": "Smith", "modified": "2006-12-31T23:59"
