Topic: Discovered Issue with filter exists

ValueSet.compose.include.filter.op has a value 'exists'
Grahame Grieve (Feb 15 2017 at 02:42):
the definition for this (http://build.fhir.org/valueset-filter-operator.html) makes it sounds like there's no use for ValueSet.compose.include.filter.value - but value is 1..1
Rob Hausam (Feb 15 2017 at 20:07):
yes - to use this we would need to make ValueSet.compose.include.filter.value 0..1
you could also achieve this using 'regex', but it would be simpler and cleaner using 'exact'
I believe this also applies to CodeSystem.filter.value (although 'operator' is 1..* - not sure how that works?
Michael Lawley (Feb 19 2017 at 23:20):
I assumed you'd use a boolean - "exists = true" or "exists = false"
Grahame Grieve (Feb 20 2017 at 12:53):
yes that's what we decided to do. I don't know why I didn't think of that immediately
