2023 COSA Dataset-JSON Hackathon II Registration

Description: Our first Dataset-JSON Hackathon was a success, providing 21 solutions that use Dataset-JSON. 

We look forward to similar success with Dataset-JSON Hackathon II.  Unlike the first hackathon, participants in Hackathon II will work together as a team. The outcome will be a draft API specification for Dataset-JSON. The team will receive a starter set of use cases, which they will refine and extend. Once the team completes the API specification, CDISC will release it for comment.

Objectives:

  • Primary objective: Create a draft API specification for Dataset-JSON
  • Secondary objective: Develop proof-of-concept implementations to demonstrate and test the API specification

Key Dates:

  • Kickoff: 31 Aug 2023
  • Virtual Hackathon: 1 Sep – 19 Oct 2023

What is JSON?

An open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays.

What is Dataset-JSON?

A dataset exchange standard for exchanging tabular data leveraging JSON designed to meet the regulatory submission needs and eliminating limitations of legacy formats.

Dataset-JSON is:

  • Part of the ODM v2.0 standard
  • An open-source MIT license
  • Schema supporting any tabular format
  • Extensible to support integrated metadata and new use cases
  • Linked to Define-XML for complete metadata
  • Integrated with CORE for conformance checking

Dataset-JSON Advantages:

  • Based on the JSON standard used worldwide
  • Open-source and truly human readable
  • Same or smaller file sizes relative to current required format
  • Removes variable naming, width, or format limitations
  • Simple transformation to/from SAS data
