Topic: resolving valueset.system to a codesystem

Simone Heckmann (Feb 07 2017 at 13:16):

I created a valueset valueset-billing-codes.xml with

  <compose>
    <include>
      <system value="http://hl7.org/fhir/ebmcode-examples"/>
    </include>
  </compose>

and a codesystem codesystem-ebmcodes-examples.xml with
<url value="http://hl7.org/fhir/ebmcode-examples"/>

Build exits with

 [java] ERROR @ pa:ValueSet[billing-codes].compose.include[1]
 The system 'http://hl7.org/fhir/ebmcode-examples' is not valid

What am I missing. Do I have to register the codesystem somewhere?

RTFM answers welcome, if link is provided (I can't find anything...)

Think you're out of luck. It's hardcoded.

Vadim Peretokin (Feb 07 2017 at 13:29):

here is where the error is coming from, and it's checking isKnownCodeSystem(), which is a list here

Simone Heckmann (Feb 07 2017 at 13:36):

This looks like a list of systems that *don't* resolve in FHIR, because they point at external code systems, no?
But a valueset referencing an existing codesystem should work. I checked similar examples of valuesets referencing existing codesystems that are not explicitly listed in ValueSetValidator.java but still work.

I think I am just missing a place that establishes the reference between the system url and the codesystem filename...
