Meeting: FHIR RDF

14:55:29 [dbooth]

Chair: David Booth

15:13:51 [dbooth]

Topic: DICOM

15:20:38 [dbooth]

dbooth: There are two cases: things that are not known -- someone's birthday -- versus something that will never be known, like a probe was broken and we didn't get a measurement at this point in time, and therefore we will never have a value for that thing.

15:28:44 [dbooth]

gaurav: Would this be useful in specifying that e.g. a fhir:Observation is missing because it was not permitted/not permitted/not applicable? https://build.fhir.org/valueset-data-absent-reason.html

15:28:56 [dbooth]

gaurav: There is also “IND” (indeterminate) in https://build.fhir.org/valueset-observation-interpretation.html

15:29:16 [dbooth]

gaurav: FHIR provides a limited way to indicate that something is missing in an observation.

15:30:41 [dbooth]

rob: representation of null values is important. Two distinct cases. Not sure whether we need separate syntaxes for them.

15:31:07 [dbooth]

erich: I shared null flavors info about DICOM with EricP

15:36:36 [dbooth]

ACTION: Erich to add option 6 for a single blank node
