September 2025: Focused on improving data accuracy and visualization for pregnancy and childbirth data in Nictiz/HL7-mappings. Key outcomes include a robustness fix removing inappropriate 'partOf' references for non-bevalling procedures, and a visualization refresh that regenerates FHIR instances and updates HTML/JS visuals to align with the latest FHIR structures and discard outdated references. These changes strengthen data interoperability, reduce incorrect mappings, and enable more reliable maternal health analytics across downstream systems.
