Topic: Composition Section Section

AbdulMalik Shakir (Oct 21 2021 at 00:29):

Does anyone have a functioning example of a composition in which a composition.section includes a sub-section (i.e., composition.section.section? How are elements and entries of the subsection specified in the structure definition?

Jean Duteau (Oct 21 2021 at 05:26):

Do you mean a profile that includes sub-sections? Or an actual instance example? I have both: Example instance - Composition-SampleSPLDocument.json Profile - http://build.fhir.org/ig/HL7/fhir-spl/branches/main/StructureDefinition-ProductSubmissionDocument.html

Thanks @Jean Duteau is it not possible to place constraints on the subsections allowed in a section. At first, I wondered how the elements of the subsection were exposed in a profile structure definition. Looking at your example I see that the elements of the subsection are all of the elements of section, but I don't see how those elements are contained. Am I missing something?

Grahame Grieve (Oct 23 2021 at 18:39):

it is possible - you just keep walking into the sub-section structure

You'll need to define slicing within a slice. I.e. you slice the base section. Then, within that, you'll slice the sub-section.

I just added some constraints on the sub-section in one of my section slices and it looks like this:

      {
        "id": "Composition.section:OtherSections.text",
        "path": "Composition.section.text",
        "min": 1
      },
      {
        "id": "Composition.section:OtherSections.entry",
        "path": "Composition.section.entry",
        "max": "0"
      },
      {
        "id": "Composition.section:OtherSections.section",
        "path": "Composition.section.section",
        "type": [
          {
            "code": "BackboneElement"
          }
        ]
      },
      {
        "id": "Composition.section:OtherSections.section.text",
        "path": "Composition.section.section.text",
        "min": 1
      },
      {
        "id": "Composition.section:OtherSections.section.entry",
        "path": "Composition.section.section.entry",
        "min": 1,
        "max": "1"
      }

Thanks all. I see how to do this manually, I guest that the limitation I was seeing was in TOF only. @Rick Geimer ?

Saul Kravitz (Oct 26 2021 at 05:01):

Hi @AbdulMalik Shakir , don't you want do just slice sections by title, and slice by profile within a section with a given title, rather than have a hierarchy of sections?
Something like this (two sections, and only one profile defined per section just as an illustration) -- http://build.fhir.org/ig/saulakravitz/vrdr/branches/FSHversion/StructureDefinition-VRDR-Death-Certificate.html

Lloyd McKenzie (Oct 26 2021 at 13:21):

Title is a human-readable value and is totally unconstrained. Slicing on it is generally not a good idea. (Any change to capitalization, spacing, spelling, etc. will cause the slicing rules to not work). Much better to slice by section.code which is computable and can be constrained.
