Hi All,
Just a heads-up that the upcoming release of HAPI adds a terminology server which supports a bunch of funky new stuff including ValueSet expansion with filtering and text search, and searches like Observation?code:in=foo and Observation?code:below=foo.
If anyone wants to test this, that would be greatly appreciated. Our public server has been loaded with SNOMED CT (international edition) and LOINC.. hopefully more to come. Endpoint is here: http://fhirtest.uhn.ca/baseDstu3

That's fabulous! Do you include load scripts for SNOMED and LOINC?
James Agnew (Jun 24 2016 at 22:12):
Yup. The CLI will have the ability to load either of those CS's from their respective distribution zips.
It's a bit of a painful process, the SCT import takes about an hour on my high-powered laptop but it's pretty zippy once it's loaded.

Before I go testing, does it support the $expand option on multiple filters?
James Agnew (Jun 27 2016 at 14:50):
Yup, It should support this. FYI David Hay gave it a whirl on Friday and promptly discovered that it wasn't properly expanding codes that have multiple parents. That's now fixed.
If you find anything else you think should work but doesn't, awesome.
James Agnew (Jun 27 2016 at 15:26):
Incidentally, here's a sample David provided: http://fhirtest.uhn.ca/baseDstu3/ValueSet/condition-code/$expand?filter=ankylosing
Eric Haas (Jun 27 2016 at 23:47):
@James Agnew When I run David's sample, the output parameter is not a valid ValueSet resource. There are missing elements between the meta and expansion elements.
James Agnew (Jun 28 2016 at 13:53):
Oops, that was missing. Fixed.
This brings me to a different question though.. Should/can the output ValueSet of the expansion contain the ValueSet.compose element that caused the expansion? The invariants allow this, the description is silent, and the examples don't have this.
Grahame Grieve (Jun 28 2016 at 19:49):
James - so you haven't noticed ExpansionProfile? See ExpansionProfile.includeDefinition
James Agnew (Jun 28 2016 at 19:50):
whoa! no, i didn't know about that....
FHIR terminology services are really elegantly designed, I like it.
Michael Lawley (Jun 28 2016 at 23:10):
Mostly elegant, but not ExpansionProfile IMO - being full of binary flags leads to combinatorial explosion of instances & not a good experience for client or server programmer
Rob Hausam (Jun 30 2016 at 12:19):
That's excellent, James. I'll start testing it - both on your public server and on mine.
