Apple's CareKit (HealthKit) - what kinds of clinical data does it work with?

I thought Apple had given up on HealthKit, but recently we learned that it’s been rebranded as CareKit and it seems to be going forward.

Since my professional work is in “health informatics”, specifically medical knowledge applications, I was curious what “ontology” (data dictionary, terminology, etc) Apple was using for it’s CareKit work. The concept set is somewhat hidden within Apple’s HealthKit Constants Reference documentation. I auto-expanded the symbols (nice web app Apple!) and make a quick pass at organizing the strings.

For someone like me it’s a fascinating set. The discussion of privacy and FDA device identifiers is noteworthy — in an early implementation it was apparently possible to trace HealthKit data to an individual device (not good, obviously - bold below).

I liked the use of Fitzpatrick Skin Type instead of trying to describe ethnicity/race.

It’s a fun list to scan:
