What do you think about the following logic related to AQL? The following AQLs will be intepreted as logical equals for the AQL engine. The first AQL 1.0 is a short hand query for the full AQL defined as AQL 1.3. The examples is given here: openehr-conformance/aql/index.adoc at master · bjornna/op…

Sorry for being unclear :slight_smile: The question is if you agree that the given AQL’s will produce identical results. The given AQLs are, in our opinion, equal. They are different syntactic variants of the same maximal AQL given in AQL 1.3. Take a look at the original page for more details abou…

they are all equal assuming the most common interpretation of CONTAINS semantics, which you’ve made explicit in 1.3.

They look functionally equivalent (or at least quite close) to me. But I have few small questions: one is about not using “EHR e”, is that allowed? will that assume there is an EHR somewhere in the context? or is it implying all EHR available on system? in the AQL there is nothing like VERSIONED_…

syntactically, not having EHR is OK. We have a dedicated… “festival” going on regarding the definition of FROM, as you know :slight_smile: The syntax of AQL currently requires that you have a single root in the FROM clause, as in FROM X… Again syntactically, that X can be any RM type with/without …

I’m sorry, but I’m not sure what is the question (the catch) here. Can you rephrase it?
