Hi Georg,
currently, this is not possible directly using AQL. However, technically
it is possible to make a look-up within all archetypes to automatically
retrieve the elements (and their paths) that have a matching
terminology-binding (for example to the snomed code for gender). This
path could then be used within an AQL query which can use the code for
"male". I actually was thinking about building such a tool within
HiGHmed make analytics quers more convenient, though we are still
searching for a developer.
Hope this answers your question,
Birger

Hello,
In AQL it is possible to constrain the value of a node to one of the
codes that are allowed for that value (as specified in the respective
archetype).
To find patients with gender (snomed-ct:248153007) male
(snomed-ct:248153007) I could write something like this:
SELECT e FROMEHR e CONTAINSDEMOGRAPHICS d
WHERE d.items[at0017].value = 'snomed-ct:248153007'
Is it possible to identify the node of an archetype instead of its
path parts (e.g. d.gender or d.items[at0017]) also with a terminology
code, so the query would rather look like something like that:
SELECT e FROMEHR e CONTAINSDEMOGRAPHICS d
WHERE d.items['snomed-ct:263495000'].value = 'snomed-ct:248153007'
I am not very experienced with AQL so the queries are probably already
syntactically wrong.
Greetings
Georg
