Topic: How to use Jurisdiction codes
Matthijs van der Wielen (Dec 15 2021 at 07:39):
When you include the Jurisdiction in a package manifest you can use three different CodeSystems, the ISO-3166, ISO:3166-2 and unstats.un.org. Now I am not entirely sure what the right way of using the ISO:3166-2 is. How do I include the "-2" part. For example if I want to get the Jurisdiction for England, according to https://build.fhir.org/valueset-jurisdiction.html it should something like: urn:iso:std:iso:3166:-2:GB-ENG
The two things I want to confirm is:
- whether there should be a ":" before "-2" since this does not appear on https://en.wikipedia.org/wiki/ISO_3166-2:GB
- and whether the code should be preceded by a ":" or a "#" which used in the hl7.fhir.us.ecr package manifest: https://simplifier.net/packages/hl7.fhir.us.ecr/1.1.0/files/297990

If I remember correctly (from discussions related to language codes) -2 need not be mentioned, the parts are 'value sets' within one and the same code system. But I stand to be corrected, this not being my primary area of expertise.

The reason behind this is to distinguish England NHS profiles from the wider UK (& NHS) profiles.
So we don't cause confusion in Scottish or Welsh NHS.

We can move to the UK code (GB) if this causes issues.
Matthijs van der Wielen (Dec 15 2021 at 08:52):
It should be possible to use the 3166-2 valueset since it is in the jurisdiction valueset in build.fhir.org. The thing I want to make sure is how we should use the codes correctly.

The URL for the code system doesn't change, just the code.
Matthijs van der Wielen (Dec 16 2021 at 11:15):
@Lloyd McKenzie Thank you for the input. If I understand you correctly, the example that Kevin mentioned, would than be urn:iso:std:iso:3166:-2#GB-ENG. Right?
Lloyd McKenzie (Dec 16 2021 at 19:28):
The url would be "urn:iso:sdt:iso:3166:-2". The code would be "GB-ENG".
Elliot Silver (Dec 16 2021 at 23:04):
@Lloyd McKenzie , is that the right code system url? I thought it was all urn:iso:std:iso:3166 as the code system for 2-letter (http://hl7.org/fhir/ValueSet/iso3166-1-2) and 3-letter (http://hl7.org/fhir/ValueSet/iso3166-1-3) country codes (collectively value set urn:iso:std:iso:3166) and subnational jurisdictions (value set urn:iso:std:iso:3166:-2). There isn't a separate code system for subnational codes.
Lloyd McKenzie (Dec 16 2021 at 23:15):
Ah, you're correct @Elliot Silver. Thanks for checking.
Elliot Silver (Dec 16 2021 at 23:23):
No problem, I've fought with those value sets enough, so might as well save others the pain.
