MarkLogic Server 11.0 Product Documentationjson functions
The table below lists all the
json built-in
functions (in this namespace:
http://marklogic.com/xdmp/json).
This is the JSON module used for customized tranformation from XML to and from JSON.
To use the JSON module as part of your own XQuery module, include the following line in your XQuery prolog:
import module namespace json = "http://marklogic.com/xdmp/json"
at "/MarkLogic/json/json.xqy";
The JSON module employs a concept of 'strategies'. Strategies are different methods of transforming XML to JSON or JSON to XML. Different strategies tackle different use cases.
The basic strategy is used by the REST API and
handles the use case of transforming arbitrary JSON into a
fixed XML structure which is designed to be efficiently
stored and indexed in MarkLogic.
The basic strategy is semantically
roundtrippable from JSON to XML back to JSON. The
basic strategy is
used when no configuration object is specified.
The full strategy targets the opposite use case
as the default (basic) strategy.
The full strategy
takes arbitrary XML and produces a fixed JSON structure
which preserves most of the semantics of the XML
document.
The custom strategy allows customization of the
JSON and XML transformation and produces more reasonable
looking XML or JSON at the expense of supporting a
smaller subset of XML document structures.
See also the xdmp:from-json and xdmp:to-json functions.
