Hello everyone!
I am in the process of creating an archetype for the Seattle Angina Questionnaire-7 (SAQ-7) (the full questionnaire can be viewed here on page 644). You can see an overview of the panel hierarchy of the questionnaire on the LOINC website.
During the modeling process I was wondering about how to model the structure of the questionnaire including the panel hierarchy with superordinate and subordinate questions.
Option 1
Should I use a CLUSTER for question 1 to represent the superordinate question and slot the subordinate questions 1a.-c. as ordinals?
I doubt that this is the intended use of a CLUSTER but have seen this approach in several score/questionnaire archetypes of which none have been published yet. When querying for this Cluster with AQL you get the values of each ordinal as a response which is quite nice.
Option 2
Alternatively, the questionnaire could be modeled with ordinals only, but then the parent question might have to be repeated in the descriptions of question 1a-1c:
This seems to be more inline with the modeling guidelines.
But let’s say I want to render this questionnaire directly from an .opt-template using the description fields that include the full-text questions. Then the second approach would render the superordinate question 1 for each of the 3 first questions.
I hope I could get my question across in a understandable way 
and I am looking forward to hearing your input!
Best,
Jannis
