This project is used to manage the JSON representation for Clinical Datasets (a complement to the Dataset-XML representation). The schema is automatically generated from a Typescript representation of the model.

1. Clone the repository

   git clone https://github.com/cdisc-org/DataExchange-DatasetJson.git
   

2. Install required packages (required only once)

   cd typescript
   npm install
   

3. Create a branch from master for your updates

   git checkout -b feature/<new_facet>
   

4. Update the schema by editing the dataset.ts file
5. Convert Typescript definitions to JSON Schema; this will update file dataset.schema.json in the schema folder.

   npm run schema
   

6. Push your branch to the upstream repository

   git push -u origin feature/<new_facet>
   

7. Raise a Pull Request for the update

The examples/big_xpt folder contains scripts to create a large XPT file (5Gb) from the XPT file examples/sdtm/lb.xpt.
