Description

Description of Issue

CQL identifier not resolving when Library that contains the CQL does not match the FHIR Library.id, Library.name and CQL.name, when it should allow FHIR Library.id to be different than library.name when library.name equals cql name.

CQL specification says:

  • FHIR Library.name should equal CQL name
  • CQL name allows A-Z and digits 0-9 and underscores
  • FHIR resource.id allows A-Z, digits 0-9, period or hyphens, but no underscores

When specifying a Library and CQL as:

cql file

library AABReporting version '2024.2.0'

FHIR library

  "resourceType": "Library",
  "id": "AABReporting-2024.2.0",
  "url": "http://ncqa.org/fhir/Library/AABReporting-2024.2.0",
  "version": "2024.2.0",
  "name": "AABReporting"
}```

# Observed results

Throws error: "Unable to load CQL/ELM for library: %s. Verify that the Library resource is available in your environment and has CQL/ELM content embedded."

# Expected result

No error

Research direction

No files, tests, or entry points are named. Reproduce the example with CQL library AABReporting and FHIR Library id AABReporting-2024.2.0, then trace identifier resolution for the Library.id, Library.name, and CQL name; done means the example resolves without the reported loading error.
