Project Scope 

The scope for the project covers twin objectives:

  1. Demonstrate that Dataset-JSON can transport information with no disruption to business​
  2. Demonstrate the viability of Dataset-JSON as the primary transport option
Sub Teams

1. Pilot Submissions Report

  • Consolidate feedback from the pilot submissions and develop report

2. Business Case

  • Establish the overall business case for using Dataset-JSON for submissions to justify the investment needed to implement the changes​

3. Technical Implementation

  • Develop and document software tools to be used in the pilot to include updates to existing products​

4. Strategy for Future Development

  • Define a roadmap for future development and changes to the CDISC Foundational Standards
Project Impact 

The XPT file format is outdated and imposes limitations on submission data due to the lack of modern features – for example, XPT files are limited to US ASCII Character encoding, have restricted variable names/sizes, inefficient use of storage space, use a non-extensible tabular structure and lack any integrated metadata. The impact of overcoming these limitations will be seen initially by regulators; however, by far the bigger impact will be seen in the medium to longer term, where, by lifting the restrictions of XPT, and moving to Dataset-JSON, new standards will be able to take advantage of these enhanced capabilities, and drive efficiencies, consistency and re-usability across the clinical research data life cycle.
