Overview

Fusion-JSON is a format used for Structural Metadata, Data, and Reference Metadata. The Fusion-JSON format was created before the SDMX-JSON format became a standard as so has a slightly different syntax. In addition the Fusion-JSON format is used for Structural Metadata that is supported by the Fusion Registry which is not a part of the official SDMX Specification. This includes:

Fusion-JSON Data

Fusion-JSON for data consists of three top-level nodes:

  • header
  • dataSets
  • structure

Unlike SDMX-ML data formats, Fusion-JSON is self-describing in that it contains both the observation data and structural metadata needed to interpretet.


1This includes a Data Structure Definition that has one or more Components that use a Valuelist to define their allowable content. Also Data Structures that do not define a Measure with ID OBS_VALUE (the Primary Measure), or a Data Structure with multiple Measure Dimensions.
