During February 2025, this developer contributed to the ansforge/IG-terminologie-de-sante repository by delivering two core features focused on French health terminology interoperability. They built a ConceptMap resource to establish equivalences between department and registration authority codes, supporting standardized data exchange. Their work included finalizing the Departement-AE resource, updating its URL, version, and date fields to ensure accurate release tracking and governance. Using FHIR, FHIR Shorthand (FSH), and terminology management skills, they concentrated on resource mapping, version control, and release readiness. The updates improved integration with downstream systems and clarified release artifacts, with all commits emphasizing documentation and maintainability.
