Topic: Modifier extension on ElementDefinition?
Michel Rutten (Apr 08 2019 at 13:10):
In R4, ElementDefinition is now derived from BackboneElement (STU3: Element):
http://hl7.org/fhir/elementdefinition-definitions.html#ElementDefinition
What is the use case for putting a modifier extension on an ElementDefinition?
Are there any concrete examples?
Grahame Grieve (Apr 08 2019 at 19:50):
we have no concrete examples but we made the change as part of a set of changes where the data types that were not general purpose datatypes used in more than a few places were change to specialise backbone element - Dosage, and Timing, in particular had known use cases. But I can imagine use cases where you want to say something about a data element that is not ignorable
Grahame Grieve (Apr 08 2019 at 19:50):
I don't think you need to support extensions or modifier extensions on Forge except by specific request
Grahame Grieve (Apr 08 2019 at 19:51):
(thought it would be good to preserve what exist)
Michel Rutten (Apr 10 2019 at 08:58):
OK, thanks for clarification @Grahame Grieve
