I also started creating a summary of the options here (not yet complete):

Meeting minutes

   extending primitive types


       [4] https://github.com/w3c/hcls-fhir-rdf/issues/77

    david: I think that option 2b is better than 2.

    emily: agreed

    eric: Not sure of implications of having birthDate be both a
    datatype property and an individual.

    david: We're looking at this comparison: [5]https://


    brad: would a SPARQL query be harder in option 2 or 2b?

    eric: option 2 has an easier property path than 2b.

    gopi: I prefer 2.

    gaurav: I prefer 2b

    emily: I prefer any option that reduces bnodes

    david: 1a vs 1b?

    eric: I like {2, 2a} better than {1a, 1b}

    brad: I also don't like 1a or 1b.

    gaurav: Pref 2 and 2b better also.

    david: Propose dropping 1a and 1b from consideration.

    eric: seconded. Brad also.

    AGREED: dropping 1a and 1b from consideration

    david: Preferences of 3 vs 2 or 2b?

    eric: prefer 3 over 2, 2b

    eric: I think 3 would be on the right path toward modifier
    extensions also.

    david: I also prefer 3 over 2 and 2b

    brad: I also prefer 3 over 2 and 2b.

    david: Propose dropping 2 and 2b from consideration

    eric: seconded.

    james and gopi: Also prefer 3 over 2 and 2b.

    gaurav: sligtly prefer 2, but okay with going with 3.

    AGREED: dropping 2 and 2b from consideration

    david: 3b removes one level of property path and declares the
    extension object as a fhir:Extension.

    eric: Not strictly necessary to declare the type as
    fhir:Extension (because it's known from the range of _active).

    brad: prefer 3b over 3.

    david: prefer 3b over 3.

    eric: I like 3b also.

    david: Propose that we drop 3 from consideration

    gaurav: seconded.

    AGREED: drop 3 from consideration
