FHIR CodeSystem Fixes

[jamlung-ri]

On today's OCL Dev call, we talked through some of the issues that prevented the FHIR IG Publisher from generating a FHIR IG. The diffs of manual changes that I had to make can be found here and here.

Changes needed to OCL's FHIR Core CodeSystem:

• [x] “Count” field does not count inactive codes, but OCL FHIR Core does return inactive values (which was pointed out via the FHIR Validator)
  • Solution: "Count" needs to count all codes, whether active or inactive.
• [x] “Null” fields are intended to be excluded in FHIR e.g. "definition": null (see second-to-last paragraph on this page)
• [x] Concept Property’s “value” should be “valueString”
• [x] Had to add a whole new property -- "content": "complete" (FHIR Spec)
• [x] "type": "coding" -> "type": "Coding" (FHIR Spec)

I am attaching the current OCL FHIR CodeSystem resource and the one that I hand-edited, for reference in a comment below

@jamlung-ri the changes should be deployed to QA in a few minutes, see https://ci.openmrs.org/browse/OCL-OCLAPI2-1991

[jamlung-ri]

Awesome, I tested this in QA and the diff is looking exactly how I expected!

And then it worked when testing against the FHIR IG Publisher! See this page for the new and improved CodeSystem, entirely created from OCL with no manual alterations: https://jamlung-ri.github.io/smart-catopia-measles/CodeSystem-VaccineProducts.html and https://github.com/jamlung-ri/smart-catopia-measles/blob/main/input/resources/CodeSystem-VaccineProducts.json

@rkorytkowski This should be ready to deploy to other environments.
