[Question] How to map the panel name into phenopacket?

[A-Tsai]

Hi,

I would like to adopt Phenopacket v2 as data model to store all of NGS-based diagnostic tests, such as F1 CDx, Onconine Comprehensive assay, Illumina TSO500, etc. To record the panel type, I think the suitable position is the member variable "disease" in Diagnosis. It is OntologyClass so that I can give these panel names in the member variable. However, the name "disease" make me confused because these diagnosis tests don't focus on a single disease. Here, my question is: Is the member variable "disease" in Diagnosis the right position for my use case? If no, which one will be better? If yes, is the variable name "assay" more precise than "disease"?
Thank you.
