Topic: CQL and subsumption
Erich Schulz (Jun 12 2016 at 09:58):
so... I'm just trying to digest "HL7 Standard: Clinical Quality Language Release 1" (from May 2015) - very curiously they completely ducked subsumption: on page 61 it says "The reason for this omission is that subsumption is
generally a very complex operation, with different terminology systems providing different
mechanisms for defining and interpreting such relationships. As a result, specifying how that
occurs is beyond the scope of CQL at this time. This is not to say that a specific library of
subsumption operators could not be provided and broadly adopted and used, only that the CQL
specification does not attempt to dictate the semantics of that operation."

I'm just curious is if anyone is across what has happened in this space since this spec was drafted?
Erich Schulz (Jun 18 2016 at 14:04):
its just i'm getting kind close to this being the pointy bit of proceedings
Erich Schulz (Jun 18 2016 at 14:05):
the CQL->JS conversion is actually coming together nicer (and faster) than I expected
Erich Schulz (Jun 23 2016 at 00:45):
@Michael Lawley is your team looking at CQL at all?
Erich Schulz (Jun 23 2016 at 00:45):
it has a few relatated ideas...
Erich Schulz (Jun 23 2016 at 00:47):
"code", "concept", "Valuesets"
Erich Schulz (Jun 23 2016 at 00:48):
I'm sure @Bryn Rhodes's team has ideas about this but haven't found a pot of examples yet
Erich Schulz (Jun 23 2016 at 00:51):
I'm planning on injecting 2 services into the Javascript code produced by the CQL->Js transpiler - one for clinical FHIR resources (i'm pretty clear on how that will work), and another service for handling terminology-based queries
Erich Schulz (Jun 23 2016 at 00:52):
but I'm still woolly on what that second service will need
Erich Schulz (Jun 23 2016 at 00:54):
I'm working on getting the primitive language constructs operational (hopefully be functional in about a week)... and then on to building a REST FHIR client to handle CQL "retrieve" operations
