Topic: How to PATCH an extension?

Alexander Zautke (May 02 2021 at 17:52):

I'm currently trying to figure out how to interpret the section on the PATCH operation about Anonymous Types. I'm looking for a solution on how to add an extension using a single PATCH operation to a resource. For me the part regarding "a set of parts that are values are provided" is not totally clear. I'm unsure how it's supposed to look like. I didn't find any example in the test case downloads either which would provide more than one value as a part.

Say I've defined an "Add" operation with the path "Patient" and name "extension", would the following part be correct to add an extension?

{
    "name": "value",
    "part": [
        {
            "name": "url",
            "valueUri": "https://example.org/fhir/StructureDefinition/MyPatchExtension"
        },
        {
            "name": "value",
            "valueString": "test"
        }
    ]
}

Or should the "value" part be repeating with a single part in it?

Extending this to complex extensions ("This pattern repeats as deep as necessary")
My initial guess would be the following:

{
    "name": "value",
    "part": [
        {
            "name": "url",
            "valueUri": "https://example.org/fhir/StructureDefinition/MyPatchExtension"
        },
        {
            "name": "extension",
            "part": [
            {
                "name": "url",
                "valueUrl": "MyComplexExtensionElement"
            },
            {
                "name": "value",
                "valueString": "test"
            }]
        }]
}

Anyone already experimented with this before?

have you looked at the test cases? https://github.com/FHIR/fhir-test-cases/blob/master/r5/patch/fhir-path-tests.xml

Alexander Zautke (May 04 2021 at 08:19):

Yes, I only see two examples which are related to the anonymous type section ("Add Anonymous Type" and "Delete Anonymous Type"). Do you have a different case in mind which would cover the scenario mentioned above?

Grahame Grieve (May 04 2021 at 10:18):

no I hoped there was one already

Grahame Grieve (May 05 2021 at 03:46):

ok. so i think that your examples above are correct
