Topic: Int type question in R4 StructureDef

Gino Canessa (Feb 21 2020 at 23:05):

I'm switching tooling over to use the fancy NPM structure defs, and noticed that in R4 positiveInt and unsignedInt are represented with a FHIR type of http://hl7.org/fhirpath/System.String, instead of in R2-R3, where they were typed by various integer types (e.g., xsd:positiveInteger).

Is this an intentional change, or something that got lost in translation?

Grahame Grieve (Feb 21 2020 at 23:09):

intentional

Grahame Grieve (Feb 21 2020 at 23:09):

I can find the task if you want

Gino Canessa (Feb 21 2020 at 23:14):

No worries, just wanted to make sure I wasn't crazy when I saw the output :-)
Thanks!

I'm having trouble interpreting snapshot vs differential in this definition:

Snapshot has:

      {
        "id": "positiveInt.value",
        <snip>
        "type": [
          {
            "extension": [
              {
                "url": "http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type",
                "valueUri": "string"
              },

... while differential has:

      {
        "id": "positiveInt.value",
        <snip>
        "type": [
          {
            "extension": [
              {
                "url": "http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type",
                "valueUri": "positiveInt"
              },

Josh Mandel (Feb 21 2020 at 23:20):

Is there a reason one says string and the other says positiveInt?

Josh Mandel (Feb 21 2020 at 23:20):

(From package/StructureDefinition-positiveInt.json in http://build.fhir.org/hl7.fhir.r5.core.tgz)

Grahame Grieve (Feb 21 2020 at 23:34):

it should both be Integer

Josh Mandel (Feb 21 2020 at 23:36):

So string should say integer instead; and also positiveInt should say integer instead?

Josh Mandel (Feb 21 2020 at 23:37):

(Do you stand by your answer to Gino's question above?)

Grahame Grieve (Feb 21 2020 at 23:38):

oh no, hang on

Grahame Grieve (Feb 21 2020 at 23:39):

they should both have the type http://hl7.org/fhirpath/System.Integer and the value of http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type should be positiveInt for both
