Users can retrieve baseline aeronautical data via the OGC Web Feature Service (WFS) 2.0 interface. The service does not perform automatic dataset publication; instead, all data resides in the AIM database and is made available upon explicit client request. Communication follows a SOAP-based protocol over HTTP, adhering to standard web service practices. Each client request must encapsulate the WFS operation within a SOAP envelope and transmit it to the service endpoint. The server processes the request and returns an AIXM Basic Message as the response, also embedded within a SOAP envelope and body, ensuring schema compliance with AIXM 5.1 and WFS-TE specifications. The interaction conforms to synchronous request–reply message exchange patterns as defined in the Message Exchange Patterns: Identification Guidelines, guaranteeing predictable behavior and interoperability across SWIM-compliant systems.
