Hi Bert,
I was thinking about integrating SCT with path-based queries (I'm not in AQL yet), but maintaining the complexity of the SCT relationships and expressions on the terminology service (TS) side, so on queries there are just simple codes (specific concept ids, subsets or expressions identified just by one code). Then when evaluating a query, with the TS we can get all the terms and concept ids that match all the is_a relationships or subsets of expressions. I talked with several TS providers and hopefully we can build an integration next year to create and evaluate queries with SCT. What I'm saying is that I prefer to delegate the complexity of SCT to the TS and create simpler queries in AQL or path-based queries, but your idea is interesting. One problem though is that query creators need to be experts in SCT. What do you think?

The way I see it now, there is no change necessary in the reference model to integrate the potential of SCT largely. Even you can keep on using the semantic rich entry types like Observation, etc. See my post in my blog. http://www.bertverhees.nl/archetypes/needed-run-snomed-ct-expression-constraints-openehr-aql/ If you, however, limit yourself to the Generic entry type, which even gives a better integration while keeping all OpenEhr functinality alive. http://www.bertverhees.nl/archetypes/snomed-ct-expression-constraints-openehr-aql-part-2/ I am interested in what you think about that.

I think some simplifications can still be done to the openEHR IM without losing semantics, like removing ITEM_STRUCTURE and using just CLUSTER/ELEMENT (we have a discussion about this on the wiki started some years ago). IMO we should not try to make the reference model simpler just in sake of simplifying the implementation, since the other 2 models are for that. In my systems I have different implementation models that are over simplified openEHR IM implementations, and also very specific / optimized / generic persistence information models compatible with the openEHR IM. And I think the implementation / persistence models are the ones we can simplify and adjust to our needs, but not the reference model, since it's role is that: be the reference for all implementations. -- Kind regards, Eng.
