How to reference external codelist in FHIR resource spreadsheet

I’m trying to reference an external codelist by setting it up in the Bindings tab of the resource spreadsheet, with Binding=reference and Reference= https://ncit.nci.nih.gov/ncitbrowser/ajax?action=create_src_vs_tree&vsd_uri=http%3A//evs.nci.nih.gov/valueset/C66737. I see that the Account Resource (ISO countryCode) has the type of binding I’m looking for, but the URL I have is more complex than the one for countryCode.

When I build the resource, I get this error: “[java] Exception in thread “main” java.lang.Error: org.hl7.fhir.exceptions.FHIRException: not done yet: can’t fetch https://ncit.nci.nih.gov/ncitbrowser/ajax?action=create_src_vs_tree&vsd_uri=http%3A//evs.nci.nih.gov/valueset/C66737

Screen shot of error:

It looks like “reference” is the right type of binding since this is an external codelist published by NCI EVS.

Any help is greatly appreciated.

If you’re going to use Reference, it must be a properly formed Reference to a ValueSet. I.e. the URL must follow the [base]ValueSet/[id] syntax. And the build process expects to be able to find a ValueSet with that URL within the build environment. If you just want to point by URI, then

“If you just want to point by URI, then” . . .

Then?

Thx, Lloyd.
