For the pharmacorridor use case, the BDI Framework comprises a stack of components with semantic, technical, and governance blocks. Individual organisations throughout the supply chain of pharmaceutical goods can provide peer-to-peer access on shipment details. After being onboarded to the iSHARE framework, organisations can easily check and verify who has access to which information, allowing each party to decide to whom what information gets shared. This Trusted Network of Networks approach is based on webhook-based event subscriptions. Instead of repeatedly querying an API to check whether something has changed, a party subscribes to specific events—for example, a shipment being dispatched, a cargo status changing, or a delivery being completed. When such an event occurs, the system automatically sends an event notification to the subscriber’s registered webhook endpoint.

The technical requirements for these webhook subscriptions are derived from the DCSA Track & Trace standards, providing an established framework for how event subscriptions, notifications, and API interactions should function. The event schemas, however, are derived from existing IATA messaging standards, ensuring that the information contained in each event is structured according to concepts already familiar to the aviation and air-cargo sector.
