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:
          exists [Condition: Code 'C71.1' from icd10]
        """, library.print(PrintContext.ZERO));

JSON Deserialization of Structured Query

var mapper = new ObjectMapper();
mapper.readValue("""
        {"inclusionCriteria": [[{
          "termCodes": [{
            "system": "http://fhir.de/CodeSystem/dimdi/icd-10-gm",
            "code": "C71.1",
            "display": "Malignant neoplasm of brain"
          }]
        }], [{

            "code": "76689-9",

          }],
          "valueFilter": {
            "type": "concept",
            "selectedConcepts": [

                "display": "Male"
              },
              {
                "system": "http://hl7.org/fhir/administrative-gender",
                "code": "female",
                "display": "Female"
              }
            ]
          }
        }]]}
        """, StructuredQuery.class);
