MII Feasibility - Structured Query to CQL Translator

Usage

Translator

var c71_1 = TermCode.of("http://fhir.de/CodeSystem/dimdi/icd-10-gm", "C71.1", "Malignant neoplasm of brain");
var mappings = Map.of(c71_1, Mapping.of(c71_1, "Condition"));
var conceptTree = ConceptNode.of(c71_1);
var codeSystemAliases = Map.of("http://fhir.de/CodeSystem/dimdi/icd-10-gm", "icd10");
var mappingContext = MappingContext.of(mappings, conceptTree, codeSystemAliases);

Library library = Translator.of(mappingContext).toCql(StructuredQuery.of(List.of(
        List.of(ConceptCriterion.of(c71_1)))));

assertEquals("""
        library Retrieve
        using FHIR version '4.0.0'
        include FHIRHelpers version '4.0.0'

        codesystem icd10: 'http://fhir.de/CodeSystem/dimdi/icd-10-gm'

        define InInitialPopulation:

JSON Deserialization of Structured Query

mapper.readValue("""
