Stream: IG creation
Topic: Choice of Profiles
Chris Moesel (Jun 27 2018 at 22:10):
A colleague of mine has a profile on Patient that specifies the identifier element type as a choice of profiles:
"type": [
{
"code": "Identifier",
"profile": "http://nightingaleproject.github.io/fhirDeathRecord/StructureDefinition/sdr-decedent-DecedentID"
},
{
"code": "Identifier",
"profile": "http://nightingaleproject.github.io/fhirDeathRecord/StructureDefinition/sdr-decedent-SocialSecurityNumber"
}
],
When we generate an IG, however, the Snapshot and Differential views only show the first profile (sdr-decedent-DecedentID). Is this an issue in the IG tooling, or are we wrong to turn a non-choice Identifier type to a choice of two profiles on Identifier?
We're using the IG Publisher from the May 2018 ballot.

In R4, you should have one "identifier" and "profile" should be an array.
Chris Moesel (Jun 28 2018 at 12:36):
Thanks, @Lloyd McKenzie. That's good to know as we move toward R4. For R3, however, is the approach I demonstrated above valid? I think so, as invariant eld-13 says: "Types must be unique by the combination of code and profile." But since the IG publisher doesn't handle it correctly, it does give me pause.
Lloyd McKenzie (Jun 28 2018 at 18:41):
R3 doesn't allow multiple profiles for any data type.
Chris Moesel (Jun 28 2018 at 18:56):
If R3 doesn't support multiple profiles (as a choice), shouldn't eld-13 simply read: "Types must be unique by code"? Saying that they must be unique by "combination of code and profile" makes it sound like you can have two types w/ the same code but different profiles. Where does R3 say you can't have that?
Lloyd McKenzie (Jun 28 2018 at 19:11):
In R3, Reference can repeat multiple times
Lloyd McKenzie (Jun 28 2018 at 19:17):
Can't find a place that says it can't, but I can't remember the tooling ever supporting it.

@Chris Moesel you do not specify which version of FHIR you are using
Chris Moesel (Jul 09 2018 at 12:30):
Hi @Grahame Grieve . I apologize. My IG uses FHIR 3.0.1 -- and as noted above, indicating that an element should be a choice of multiple profiles (on the same base type) only shows up as the first profile when we produce the IG documentation (although the profile JSON correctly shows both choices in the type array).
