Stream: subscriptions
Topic: fhirpath-based Topics
Josh Mandel (Sep 24 2020 at 23:14):
Why is SubscriptionTopic.resourceTrigger.fhirPathCriteria 0..* ? The docs say multiple expressions are AND'd together, but doesn't FHIRPath's "and" address this need?

I think I asked this already during the connectathon
Brian Postlethwaite (Sep 28 2020 at 10:27):
If Expression was used in place of string, then you could have managed the value through a library too?
(and share expressions between mutliple subscriptions?)
In which case the multi-cardinality becomes interesting.
Gino Canessa (Sep 28 2020 at 19:05):
So, for the first: is it preferable to change to 0..1 or to state the behavior is or?
Gino Canessa (Sep 28 2020 at 19:07):
For the second, I'm not opposed to changing them to expression, but we would want to change all of them (e.g., each query criteria and the fhirPath field). Discussion?
Grahame Grieve (Sep 28 2020 at 20:31):
a library? that complex?
Grahame Grieve (Sep 28 2020 at 20:31):
I'd rather them not be an expression.

Anyone want to chime in on this?

I"m all for 0..1. I think if we start allowing huge sets within single subscriptions, we're going to kill servers.
