Description

The InCodeSystem/AnyInCodeSystem operations allows authors to determine if a String, Code, or Concept is in a given CodeSystem, or if a List of the previously mentioned types overlaps the codes in a given CodeSystem (see Appendix B).

CQL Execution currently only supports code equality and equivalence (code to code). CQL Execution does not currently have any way of expanding a CodeSystem or querying a CodeSystem. Supporting InCodeSystem would require more advanced terminological support, especially since some code systems are quite large!

Research direction

Start with the CQL specification links for InCodeSystem, AnyInCodeSystem, and Appendix B, then inspect the existing code equality and equivalence support in this repository. Done requires terminology support that can expand or query a CodeSystem and evaluate String, Code, Concept, and List inputs, but the issue names no implementation files or tests.
