json:object is the in-memory representation of maps used for json. The only difference between map:map and json:object is that the keys are ordered (which actually is not something JSON guarentees ... but we do). Your "magic function" is xdmp:to-json().
You dont do a transformation on json:object TO JSON ... its already in the form needed ... You can turn it into a JSON string using xdmp:to-json() but thats not a transformation. Transformations occur between XML <-> JSON Did that answer your question ? ----------------------------------------------------------------------------- David Lee Lead Engineer MarkLogic Corporation [email protected] Phone: +1 812-482-5224 Cell: +1 812-630-7622 www.marklogic.com<http://www.marklogic.com/> From: [email protected] [mailto:[email protected]] On Behalf Of Steve Spigarelli Sent: Monday, July 22, 2013 2:39 PM To: [email protected] Subject: [MarkLogic Dev General] json:object I'm having a difficult time understanding what good the json:object() function is. From what I can tell after using it, it is a specialized map:map object. I have tried using json:transform-to-json on the object but the transform function doesn't like that. So, what is the proper way to create a json:object and receive back the actual JSON string? For example: let $json-obj := json:object() let $_ := map:put($json-obj, "key", "value") return magic-function($json-obj) which would return {"key": "value"} What I get instead by calling json:transform-to-json($json-obj) is an invalid coercion error. Even wrapping the object and passing the node doesn't work. Any ideas? Has anyone actually used this function? From the comments in the documentation it doesn't have many comments.
