Task Status
This page is part of the ongoing SWIM communities of interest discussions. The content is working material. It should not be treated as final as it is still subject to review, comment and change.
This page holds the discussion on the information aspects of the service. It focuses on:
- understanding the information offered by the service (information definition)
- the filtering offered by the service.
Explanation
The information definition is extracted from the ATM Information Reference Model (https://airm.aero/). The AIRM is the ICAO endorsed reference vocabulary for defining air traffic management information. This means that the information definition is not just a copy of the IWXXM. However, service implementers who chose IWXXM can be assured that the semantic correspondences have been established (https://airm.aero/developers/semantic-correspondences).
