2.6.3 2.1.6.5 ND-JSON NDJSON Representation of Resources

Implementable Technology Specifications icon Work Group Maturity Level : 2 4 Standards Status : Draft

ns-json (New NDJSON ( New line delimited JSON) JSON icon ) is a variant of the JSON NDJSON format that is supported for bulk data transfer. In principle, nd-json NDJSON is a simple variation on the JSON format , but where resources are serialized with no whitespace, and separated by a newline pair (characters 13 and 10).

{ { "resourceType" : "[type]", .... } { "resourceType" : "[type]", .... } }

Example: 


{ "resourceType" : "[type]", .... }
{ "resourceType" : "[type]", .... }

The MIME-type for this format is application/fhir+ndjson .

In order to simplify nd-json NDJSON processing, each nd-json NDJSON document contains SHALL only contain resources of a single type - every line contains a resource of a particular type. (though note that resources may still contain contained resources of various types).

On the RESTful API , the nd-json NDJSON format can only be retrieved using the Asynchronous Pattern .
