Topic: Slicing Observation.component
Nathan Davis (Feb 26 2020 at 22:07):
I have a need to slice Observation.component. The thing is, I want to bind each component.code to patternCodeableConcept. I think this binding is cleaner and less restrictive than binding the system and code to fixedUri and fixedCode.
Nathan Davis (Feb 26 2020 at 22:09):
for example: <patternCodeableConcept><coding><system value="http:..loinc.org><code value="1234-5"/></coding></patternCodeableconcept>
Nathan Davis (Feb 26 2020 at 22:09):
rather than: specific elements for code.coding.code or system with <fixedCode value="1234-5"/>
Nathan Davis (Feb 26 2020 at 22:12):
I've tried using <discriminator><type value="value"/><path value="coding.code"/></discriminator> and <discriminator><type value="value"/><path value="coding.system"/>,?discriminator> But this gives me an error of "does not resolve"
Nathan Davis (Feb 26 2020 at 22:12):
Is it possible to slice in the manner I would like and if so, what should I use for discriminator.type and discriminator.path?
Nathan Davis (Feb 26 2020 at 22:12):
Thanks!
Lloyd McKenzie (Feb 26 2020 at 22:31):
<discriminator><type value="pattern"/><path value="$this"/></discriminator should work if you've declared a pattern on the component.code for each slice
Nathan Davis (Feb 26 2020 at 22:56):
@Lloyd McKenzie Thank you! That worked.
