Topic: Setting name.given and .family

Hello All,
I do not quite understand why setting name.given and name.family does not work

I have tried it in different ways, always with the same result:

"name": [
    {
        "use": "official",
        "_family": {
            "extension": [
                {
                    "url": "http://hl7.org/fhir/StructureDefinition/data-absent-reason",
                    "valueCode": "unsupported"
                }
            ]
        },
        "given": [
            null
        ],
        "_given": [
            {
                "extension": [
                    {
                        "url": "http://hl7.org/fhir/StructureDefinition/data-absent-reason",
                        "valueCode": "unsupported"
...

Currently I am trying to do it this way:

var absentName = new HumanName();
absentName.setUse(NameUse.OFFICIAL);
absentName
    .getFamilyElement()
    .addExtension(
        fhirProps.getExtensions().getDataAbsentReason(), new CodeType("unsupported"));
absentName
    .addGivenElement()
    .addExtension(
        fhirProps.getExtensions().getDataAbsentReason(), new CodeType("unsupported"));
patient.addName(absentName);

But there are always these strange _family and _given fields. Besides given == NULL.
Does anyone have a tip for me?
Thanks in advance. Marvin

the underscore are needed when adding extensions to primitive values (in JSON) https://www.hl7.org/fhir/json.html#primitive

I see, thank you @Patrick Werner .
How about validation. If the element given is required (1..1), is it sufficient to only add an extension (to _given) like in the example above, or do I still need a (primitive) value for given?

Patrick Werner (Sep 08 2020 at 08:36):

you don't need a value for given when adding the extension. The extension "populates" the primitive values (given & _given are the same element, just a technical detail in json)

okay, thank you very much
