@Dennis Ballance In response to your question on #implementers, there are a bunch of ways of querying ancestors and children. One way is to construct a ValueSet that represents the concepts you want (e.g. using filters like descendent = XXX or parent = XXX) then POST that ValueSet to /ValueSet/$expand. Another way is to use SNOMED's Expression Constraint Language, including as an implicit ValueSet url. For example, the ECL expression (<! 388441000|Family Equidae| OR > 388441000|Family Equidae|) can be used in an implicit ValueSet url like https://ontoserver.csiro.au/stu3-latest/ValueSet/$expand?url=http://snomed.info/sct?fhir_vs=ecl/%28%3C%21%20388441000|Family%20Equidae|%20OR%20%3E%20388441000|Family%20Equidae|%29

Jim, thanks so much for the suggestion. I have shared this with our team and we will explore further.
