About AIDM

IATA’s Airline Industry Data Model (AIDM) is an infrastructure project that will see the upgrade of our messaging standards development capability.

It aims to become a single point of access to store structured information including:

  • Industry-agreed vocabulary
  • Data definitions and their relationships
  • Related business requirements

Each message development project can easily leverage existing models developed by other standards groups to generate interoperable messaging standards faster and with higher quality.

Who uses the AIDM?

The AIDM and associated methodology is used by all standards groups under the governance of IATA Passenger Standards Conference (PSC) in their pursuit of modern data exchange standards.

Since its initial release in early 2016, a number of industry projects have used the AIDM to deliver new messaging standards or align existing standards to the common concepts stored in the integrated model.

What is in the AIDM?

First AIDM-generated message supporting Baggage Logistics and Conformance Services appeared in PADIS release 17.2 in the Summer of 2017.

Release 18.1, currently available on this site, also contains new models for Offers, Orders, and Seatmap delivered by the NDC AIDM Alignment project as well as models describing aircraft semi-permanent data developed by a project building new XML messages. Next release, 18.2, is expected to include all models developed as part of NDC AIDM Alignment as well as those related to ONE Order.

Want to get involved?

We are keen to collect feedback about the industry methodology that is helping standards setting move into a modern age.

The AIDM and associate methodology is maintained by the Architecture and Technology Strategy Board (ATSB). If you are Data or Business Architect from IATA Member Airline or Strategic Partner and want to take part in integrating new models to the AIDM and evolving the modeling methodology, join your peers in ATSB groups on the IATA Standards Setting Workspace.

Alternatively, please contact the ATSB Secretary for more information.
