2.1.6.5 NDJSON Representation of Resources

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

NDJSON ( New line delimited JSON icon ) is a variant of the NDJSON format that is supported for bulk data transfer. In principle, 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).

Example: 

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

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

In order to simplify NDJSON processing, each NDJSON document 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 NDJSON format can only be retrieved using the Asynchronous Pattern .
