During July 2025, this developer enhanced data validation within the AmadeusITGroup/otter repository by implementing a targeted JSON Schema update for the FC component. The work focused on introducing predefined choices for the primitiveProperty field in the FC JSON schema, leveraging JSON and schema validation techniques to enforce stricter data consistency. By enabling these predefined options, the update reduced the risk of downstream errors and established a more reliable foundation for future schema-driven improvements across FC pipelines. The approach demonstrated a clear understanding of data validation principles and contributed to more robust integrations by emphasizing schema consistency and maintainability.
