Foreword

This is a supplement to the IHE IT Infrastructure Technical Framework. Each supplement undergoes a process of public comment and trial implementation before being incorporated into the volumes of the Technical Frameworks.

This supplement is published on November 21, 2024 for trial implementation and may be available for testing at subsequent IHE Connectathons. The supplement may be amended based on the results of testing. Following successful testing it will be incorporated into the IT Infrastructure Technical Framework. Comments are invited and can be submitted using the ITI Public Comment form or by creating a GitHub Issue.

Introduction to This Supplement

Problem Statement

This profile is motivated by customer requirements for Document Digital Signatures (DSG) to use signing technology using JSON encoding vs the XML-Signature currently supported in DSG profile.

Open Issues and Questions

  1. Notes about deviation from profile are not being stated in the DSGj profile.
  2. The usage of DSGj with MHD(ITI-105) is not covered by the DSGj chapter.
  3. DSGj does not contain guidance around homeCommunityID
  4. Provision of a JSON Schema file

Closed Issues

  1. Will update the XML-Signature content module using a CP as some more clear descriptions have been written for the JSON Signature content module that would benefit the XML-Signature content module. These are not breaking changes.
  2. Added examples after Public-Comment - see ITI-Info DSG examples
