A set of information service metadata intended to promote service discovery and an initial evaluation of the information service characteristics.


This page is based on draft material and will be updated when ICAO accepts the PANS-(SW)IM. This is expected to happen in Q3 2021.

Information Service Overview

In the context of the anticipated PANS-IM, a requirement is expected for information about global information services to be made available. For the purpose a Service Overview is defined as: “a set of information service metadata intended to promote service discovery and an initial evaluation of the information service characteristics.

Service providers use Service Overviews to publicise an operational service or prospective service, the latter announcing its future availability. This information allows information service consumers to discover information services.  

Good to know

The Service Orientation Process considers the Service Overview as an outcome of the design step (the service has "prospective" status). It is then updated during the implementation step and completed at deployment (the service has "operational" status).
