SDMX-JSON Data

Overview

The SDMX-JSON Data format is an official SDMX format. It is a based on the JSON Specification,

SDMX-JSON was introduced in version 2.1 of the SDMX Specification to satisfy the use case of web disemination. SDMX-JSON has a different structure to the XML formats (SDMX-ML Generic Data SDMX-ML Structure Specific Data) and importantly transmists both component codes and labels. This approach provides all the information required to display the data in a single JSON response, as opposed to the XML formats which require separate knowledge of the Structural Metadata in order to decode the data.

SDMX-JSON data can be used as both an import and export format for the Fusion Registry.

Formatting Using Query Parameters

The following URL parameters can be used in a RESTful query for to get Generic data.

• format = sdmx-json

Example https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/WB,GCI,1.0/GHA.GCI..?format=sdmx-json

Note: The same formatting can be applied using HTTP Accept Headers as opposed to query parameters.

Example Output

The output below shows the full dataset in SDMX-JSON format , the top part of the dataset contains pointers to the structure section, used to decode the dataset
