15:07:42 <dbooth> eric: I was goign to work on use cases
15:08:03 <dbooth> ... If the model allows you to infer someone's bday afterward, it will make it optional.
15:08:55 <dbooth> ... If you want round trippability, you'll write something down for the null, and the advantage of writing json:null, you can recognize it always.
15:10:33 <dbooth> ... Roundtrippability requires some recognizable value there.

15:13:40 <dbooth> dbooth: We cannot use something like json:null for the birthday use case, because if we say that sally has bday json:null and Bob has birthday json:null, then inference concludes that they have the same birthday.
15:13:58 <dbooth> eric: I'm okay with the bnode solution.
15:14:56 <dbooth> gaurav: Have we met the goal of making this reversible?
15:15:27 <dbooth> erich: Aside from nulls, the JSON DICOM could mimic JSON-LD, but now I don't think that can happen.
15:15:52 <dbooth> .... With a blank node there, it blows up the JSON-LD representation.
15:16:51 <dbooth> ...  If we mimic DICOM XML, then it avoids the problem.
15:23:02 <dbooth> eric: For FHIR RDF roundtrippability, it depends on knowing the schema.
