Justification
The Imaging Integration working group is sponsoring a project to create a new context synchronization profile called FHIRcast (FHIR-I and CDS are co-sponsors).
We're working within the RIS/PACS community to identify a common, lightweight application synchronization standard.
This track will prototype this workflow synchronization using a webhooks pattern with FHIR as the underlying content data model according to the draft FHIRcast specification.
