The central challenge facing modern airport executives is not the volume of data, but the structural fragmentation of its ownership. Airports function as multi-stakeholder ecosystems where airlines, ground handlers, air traffic control, and retail operators maintain independent data silos. A federated data governance model is required to harmonize these streams without demanding centralized control that ignores the operational autonomy of stakeholders. The 'Data Sovereignity/Utility Trade-off' framework suggests that efficiency scales only when stakeholders retain ownership of data assets while contributing to a common, interoperable fabric. By aligning with Airport Business Digital Transformation: Data Governance and Strategy — ACI, executives can transition from reactive data silos to proactive information flows. Implementation requires a three-tier architecture: Local Autonomy (individual stakeholder processing), Semantic Interoperability (standardized tagging via IDMS), and Federated Orchestration (cross-entity visibility). According to IATA Data Management Standards (IDMS) — IATA, the absence of shared schemas remains the primary inhibitor to seamless connectivity. Executives must pivot toward 'Data-as-a-Contract' models, where every data point exchanged is governed by clear provenance and quality requirements, drawing from the principles in Guidelines for Airport Collaborative Decision Making (A-CDM) Data Exchange — EUROCONTROL. The implementation of a federated fabric requires shifting focus from data centralization to edge-computing protocols that respect the local sovereignty of the airline or ground handler. By adopting the standards established in Doc 9974: Flight and Flow Information for a Collaborative Environment (FF-ICE) — ICAO, airports can ensure that the Operating System for Modern Airports serves as the connective tissue for these disparate entities. The objective is not to aggregate all data, but to facilitate a 'single source of truth' that is contextually relevant to every participant in the ecosystem.
