The meeting was called to order at 09:00 a.m. US ET.

The antitrust rules were reviewed, and DICOM patent policy as well.

The agenda was approved:


  • Re-voted on the final text, minor corrections were addressed.

Action items:

  • The issues that need to be addressed by WG-20 II:
  • Broken links resolved (Isaac)
  • Links to Google Drive files removed (Isaac)
  • The destination URL needs to be updated.


Action items:

Pay attention to the following part: “Hub Responsibilities to Support Sharing of Structured Information

In order to support the sharing of structured information a Hub must support the following responsibilities:

  1. Support the update content and get current content requests
  2. Support of the set active resource is optional
  3. Maintain the current state of shared resources in order to support the get current content and validate parameters of requested operations as described in each operation
  4. Optionally enforce data protection levels
  5. Ensure the structural validity of FHIR resources
  6. Ensure that a specific in any request uses the same token as when a given was first encountered

A Hub is not responsible for any long-term persistence of shared information and should purge the content when the containing contextual subject is closed.

Please provide any feedback on content sharing before next WG-20 II call, which is scheduled for Monday, Dec. 16, 2019.
