               AIXM Structure and Application

• AIXM provides the standard foundation for describing aeronautical
  information
   –   Features: Runway, En route Route, Airspace
   –   Properties: Valid time, Location
   –   Data Types: code list of airspace types
   –   Metadata: Data originator

• AIXM can be used to build compliant application schemas
   –   Enable real-world implementation
   –   Digital NOTAMs
   –   Procedure Design
   –   Automated Charting

• Enables maximum flexibility while remaining ISO compliant
   – Examples this afternoon and tomorrow
                                            What is GML?

• ISO exchange format for
  geographical features encoding
   – Based on XML Schema
   – Open GIS Consortium
  <gml:Point>
      <gml:pos>46.90278 0.08111</gml:pos>
  </gml:Point>

• Good industry adoption by
  Geographic Information
  System (GIS) vendors
   – Commercial Off the Shelf Software
                                        Temporality Model

• Definition
   – A model that incorporates the concept of time
• Key assertions
   – All features are temporal with start of life and end of
     life
      • Example, A new air traffic control sector
   – All features change over time
      • Example, A VOR is out of service for a day
• AIXM Temporality Model
   – Relates features to the time extent in which they are
     valid
   – Provides various means to describe the time extent
                            Versions and Delta




• Version – The state of a feature and value of its
  properties over a time period between two changes.

• Delta – Difference between two consecutive versions.
                          Temporality Model (continued)

• Operational changes are modeled as deltas

• Deltas can be permanent or temporary:
   – Permanent delta: A set of properties that have changed or will change
     permanently. The permanent delta will result in a new baseline.

   – Baseline: The state of a feature and all of the feature properties as a result of
     a permanent delta. The Baseline state of a feature also exists when the
     feature is initially created. The Baseline state lasts until the next permanent
     delta.

   – Temporary delta: A set of values for one or more feature properties that are
     effective for a limited time. The result is a temporary change to an underlying
     feature version.

   – Version: The state of a feature and all the feature properties during the time
     period between two changes.

          This is a conceptual temporal model that can be
                     implemented in many ways
                                                      Temporality
                                                  Conceptual Model
Imagine that AML Navaid undergoes an upgrade that changes its frequency from
125 MHz to 132.5 MHz…




              1. Schedule permanent change to coincide
                 with update cycle
              2. Shutdown AML before the upgrade
              3. Perform the upgrade
              4. Start AML in test mode to evaluate
                 change
                                                                            Temporality
