Stream: conformance
Topic: FHIRPath, common uses cases

Again a question in order to "separate" the dirt-common uses of a conformance issue from the more advanced cases (so we can spent most of our time in training courses on the most-often used issues): when profiling a resource - what are the most common types of FHIRPath expressions currently in use? I'm guessing "conditionality between elements: if x, then y as well, or if x, then not y". What else comes to mind?
Richard Townley-O'Neill (Mar 08 2019 at 01:46):
There exists/does not exist one like this: a.where($this=so-and-so).exists()
Jim Steel (Mar 08 2019 at 01:47):
at least one of x or y
Jim Steel (Mar 08 2019 at 01:48):
x matches some regex (e.g. for version formats)
Grahame Grieve (Mar 12 2019 at 02:14):
if value = particular code, then (element must exist | element must be from value set)
René Spronk (Mar 12 2019 at 03:25):
Do we have a set of examples somewhere? Not of FHIRPath in general, but of how its being used in profiling? Attendees to basic profiling tutorials generally aren't programmers, and have no knowledge of XPath. So we'd better have some good examples, particularly for the common use cases.
