Hi All, I am creating FHIR resource with extension. Is it mandatory to do Extension registration? Please advise. Thank You
Lloyd McKenzie (Jul 24 2020 at 11:43):
It is mandatory that all systems that receive an instance containing the extension have access to the definition of the extension. This can be done in a few ways:
- have the canonical URL for the extension resolve to the extension definition
- put the extension definition in a public registry
- ensure that the extension is only used in a closed community and everyone in the community has the definition
