This page contains discussion about issues and considerations related to HL7's FHIR specification. When adding content to a page, be sure to uncomment the "Active" category if it is commented (surrounded by <!-- and -->) so that others can notice it and participate too.

This is the discussion page to discuss the proposed _has parameter.

Discussion

  • Issue 1: Multiple _has to the same target type

If a query has two _has parameters which point to the same type, do they have an AND or an OR relationship on the target? In other words, given the following URL:

http://foo.com/Observation?_has:Patient:subject:gender=male&_has:Patient:subject:birthDate=2011-01-01

Does this URL mean "return Observations for males who were born on 2011-01-01" or does it mean "return Observations for males and Observations for people born on 2011-01-01"
