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:
- Data Reporting Template
- Data Structure Definitions that do not conform to the standard1
- Valuelist
- Validation Scheme
Fusion-JSON Data
Fusion-JSON for data consists of three top-level nodes:
- header - header information
- dataSets - observation data consisting of a sequence of series keys together with observation values for each time period
- structure - metadata for each of the dimensions and attributes in the dataset
Fusion-JSON is therefore self-describing in that it contains both the observation data and structural metadata needed to interpretet making it better suited for driving visualisations and user interfaces than SDMX-ML where the metadata needs to be retrieved separately.
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.
