Scope for functioning observables
One of the areas where there are inheritance issues is Mental Health and here is an example:
225662002|Able to think clearly (finding)| - inherits 3 "interprets" attributes
225909006|Able to cope (finding)| - also has 3 "interprets"
373930000|Cognitive function finding (finding) - inherits 2 "interprets"
Another area is around 118230007|Hearing finding)|
25289003|Hyperacusis (disorder)| - inherits 3 "interprets"
103276001|Decreased hearing (finding)
306972000|Unable to hear loud voice (finding)| - infers many, many attributes

Just to clarify, this was a proposal for modeling which has not yet been implemented. A number of things would need to be done:
| ability | to be added as property type.
We've been discussing what abilities inhere in. Is it the person, the body of the patient, the CNS, etc. We would have to decide and move on...
We've been considering using | technique | for assessment scales, as the scales typically include assessment protocols in addition to the specific scales
Concepts for the actual activities would be a separate hierarchy, or a branch of | qualifier value |, as long as it can be reused for other purposes.

Thanks for the clarification Daniel. I don't want to occupy time in a thread here when substantive discussion is ongoing so I shall leave you to it and await reports. I'd consider technique to be how the evaluation was conducted: structured interview, self administered questionnaire, physical examination, functional test, etc? The assessment scale, tool, instrument is (the word associations aren't accidental) more akin to an ophthalmoscope, sphyg or patella hammer etc? I believe this may align with how international thinking on clinical devices in general is going i.e. that a lot of 'things' are (arguably) tools and devices even though virtual or digital. Some discussion with pharmacy/devices leads would be useful if it has not already taken place. It could even be appropriate to move the assessment scales to the devices hierarchy?

I am aware this work has been put back a bit and may be up and running again soon? I would be very interested to see some testbed worked examples of modeled functional observables if there are any at this stage. Perhaps this is planned for a future Observables meeting? The Editorial Guide provides an uncoded example (6.3.3.17) under HAS REALIZATION modeling of:
Ability to walk (observable entity)
PROPERTY TYPE | | ability
INHERES IN | | whole body
HAS REALIZATION | | walking
and identifies << 719982003 |Process as the value set for 'walking' although the current values under 719982003 are pathological processes. I am not clear how this will work.
Going on from this the (to me) very important area of observables from scored assessments seems one that needs a start making on modeling. Just picking the first one to hand: 714474007 Aachen Aphasia Test score.
PROPERTY TYPE has no values under 118598001 | Measurement property that would fit. 280433002 Summated scale score (qualifier value) would do but isn't permitted.
Looks like it would INHERE IN 'Brain structure' (body structure)
The only way I can see of fitting in the scale is under USING DEVICE but only Physical object | 260787004 is permitted so the range would need extending to include << 273249006 Assessment scales (assessment scale)?
HAS REALIZATION (or CHARACTERIZES?) would need to have values of <<Functional observable (observable entity) to allow for '(Ability to) understand or produce speech' or even all observables but then it's an Observable Entity referencing another Observable entity. I believe there was a discussion on revising the location of the function observables en masse but I am not clear how far that has got?
Sorry Penni, a lot of questions. It would be interesting to see the direction of travel.
