The specification gives examples of types of information definitions:
- standardised information exchange models
- descriptions of information exchanged by services
- data catalogues
- information exchanges captured as part of a business process model
...
The exchange models listed above relate to three ICAO business domains (aeronautical, weather and flight information). However, other exchange models exist.
A service description may refer to one of these exchange models in order to define its payload.
...
Business process modelling is a key art the service oriented approach. It is used to identify information exchange requirements, including the names and definitions of the elements being exchanged throughout the process.
