AIXM

The Aeronautical Information Exchange Model (AIXM) is designed to enable the management and distribution of Aeronautical Information Services (AIS) data in digital format. AIXM version 5.0, set to be finalized in late 2007, is based on Geography Markup Language (GML) and is one of the GML Application Schemas which is applicable for the Aeronautical domain. One main goal of AIXM version 5 is to enable 'digital NOTAM'. In this concept, the traditional free text information contained in NOTAM messages is replaced with structured information, which is suitable for automated computer processing. It is being developed by the US Federal Aviation Administration (FAA) and the European Organisation for the Safety of Air Navigation (EUROCONTROL).

Model

AIXM has two main components:

The AIXM Conceptual Model
The AIXM XML Schema

AIXM Conceptual Model

The AIXM Conceptual Model is a conceptual model of the aeronautical domain. It describes the features and their properties (attributes and associations) within the domain. Therefore, it can be used as the logical basis for AIM databases.

The model is designed using the Unified Modelling Language (UML).

AIXM XML Schema

The AIXM XML Schema is an exchange model for aeronautical data. It is an implementation of the Conceptual Model as an XML schema. Therefore, it can be used to send aeronautical information to others in the form of XML encoded data, enabling systems to exchange aeronautical information.
