Dataset-JSON was adapted from the Dataset-XML Version 1.0 specification, but uses JSON format. Like Dataset-XML, each Dataset-JSON file is connected with a Define-XML file containing detailed information about the metadata. One aim of Dataset-JSON is to address as many of the relevant requirements in the PHUSE 2017 Transport for the Next Generation paper as possible, including the efficient use of storage space.
...
At the top level of Dataset-JSON object, there are technical attributes and two main optional attributes: clinicalData and referenceData, corresponding to Dataset-XML elements. At least 1 of the main attributes must be provided. Subject data is stored in clinicalData and non-subject data is stored in referenceData.Jira
| Attribute | Usage | Description | Attribute order |
|---|---|---|---|
| creationDateTime | Required | Time of creation of the file containing the document. | 1 |
| datasetJSONVersion | Required | Version of Dataset-JSON standard | 2 |
| fileOID | Optional | A unique identifier for this file. | 3 |
| asOfDateTime | Optional | The date/time at which the source database was queried in order to create this document. | 4 |
| originator | Optional | The organization that generated the Dataset-JSON file. | 5 |
| sourceSystem | Optional | The computer system or database management system that is the source of the information in this file. | 6 |
| sourceSystemVersion | Optional | The version of the "sourceSystem" above. | 7 |
| clinicalData | Optional | Contains datasets for clinical data across multiple subjects. | 8 |
| referenceData | Optional | Contains datasets for non-subject data domains. | 9 |
...
Both clinicalData and referenceData have the same structure. Each of these attributes contains study and metadata OIDs, optional reference to the metadata file and an object describing an item group (dataset). The following attributes are defined on this level
