Added extensions not being recognized by validation?

[jbaumflek]

High-level: I'm taking HL7 ORU, converting to json, then adding to fhir server.
I've added the US_Core_Profiles in /docs/rest/PayerDataExchange - though I did this programmatically.
Validation then errored with missing us-core-ethnicity and race. So I downloaded those from HL7.org, and added them as well...but validation STILL errors on them- can't resolve them.
I don't understand what I'm doing wrong. I did alter the definitions, adding mapping for "HL7 v2 Mapping" - as I thought that might be needed for $convert.
I also am running into problems with Observation-status valueset.
This is the error there: Unable to resolve reference to profile 'http://example.com/v2-to-fhir-converter/Observation_Status'
Any pointers would be greatly appreciated.

Digging deeper...yes I should have done this first.
First off, I am using the parameter templateCollectionReference = "microsofthealth/hl7v2templates:default"
It looks like the extension template _ObservationStatus.liquid in the Liquid Converter source for Hl7v2 maps to 'CodeSystem/ObservationStatus-ext', with url of "http://example.com/v2-to-fhir-converter/Observation_Status".
I want the converter to recognize ObservationStatus as "http://hl7.org/fhir/ValueSet/observation-status", which I have added to fhir server separately.
So should I customize the template? I'd be surprised if I need to, but otherwise I'm not sure where to head...

Hi @jbaumflek! Yes, these templates are a starting place. Since HL7v2 has many different exact implementations, it's recommended that you pull the templates and change them for your own specific needs.

Check out these docs and the OSS FHIR Converter for more details.
