we recently discussed topics regarding use-cases in transplant medicine. This is a domain where the subject in entries is quite important to distinguish between donors and receivers. For example, lab values may need to be compared to create a banff classification. However, within AQL, values from donor and receiver cannot be easily distinguished as this would require an explicit statement about the subject of care within the AQL statement.
Hence, I would like to re-open the discussion if subject self should be the default and other paths belonging to entries about the donor (or fetus etc.) are only retrieved when this is stated explicitly or there is a way to provide information within the result set if a particular value is associated with a subject of care which is different from “self”.
My favorite solution would actually be, as discussed during the last(?) SEC, that a different subject then “self” changes the path in a way that it cannot be confused.
Would be great to get some feedback on this!
