The '''Aeronautical Information Exchange Model''' (AIXM) is designed to enable the management and distribution of [[Aeronautical Information Service]]s (AIS) data in digital format. AIXM is based on [[Geography Markup Language]] (GML) and is one of the [[GML Application Schemas]] which is applicable for the [[Aeronautical]] domain. It was developed by the US [[Federal Aviation Administration]] ([[FAA]]), the US [[National Geospatial-Intelligence Agency|National Geospatial Intelligence Agency (NGA)]] and the [[European Organisation for the Safety of Air Navigation]] ([[EUROCONTROL]]).The current version is AIXM 5.1.1.<ref>{{Cite web|url=http://www.aixm.aero/page/aixm-51-511|title=AIXM 5.1 / 5.1.1 {{!}} AIXM|website=www.aixm.aero|language=en|access-date=2017-03-15}}</ref>
==Model==
AIXM has two main components:
*The Aeronautical Information Conceptual Model
*The AIXM [[XML]] Schema
===The Aeronautical Information Conceptual Model===
The Aeronautical Information Conceptual Model (AICM) is a conceptual model of the aeronautical domain. It describes the features and their properties ([[Attribute (computing)|attributes]] and [[Association (object-oriented programming)|associations]]) within the domain. Therefore, it can be used as the logical basis for [[Aeronautical Information Service|Aeronautical Information Management]] databases and AIXM.
The model is designed using the [[Unified Modelling Language]] (UML).
===AIXM XML Schema===
The AIXM XML Schema is an exchange model for [[aeronautical]] data and a concrete implementation of AICM. 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.
== Purpose ==
The aim of AIXM is to allow for the management and distribution of AIS data in a digital format. This includes information such as [[airport]] area data, [[airspace]] structures, organisations and units, points and [[Navigational aid|navaids]], procedures, routes and flying restrictions. Current versions are also designed to be able to manage and distribute the full timeline of aeronautical data, including [[NOTAM|temporary updates]].<ref>{{Cite web|url=http://www.aixm.aero/|title=AIXM|website=www.aixm.aero|language=en|access-date=2017-03-15}}</ref> These features form a key part of the EUROCONTROL backed move from AIS to Aeronautical Information Management (AIM), the transition from using data based on paper documentation and telex messages to using solely digital data.<ref>{{Cite web|url=http://www.eurocontrol.int/aim|title=Aeronautical Information Management (AIM) {{!}} Eurocontrol|website=www.eurocontrol.int|language=en|access-date=2017-03-15}}</ref>
== History ==
Development of AIXM was initially started in order to facilitate the development of the European AIS Database (EAD). The development of AICM was started in 1996, with an initial release in 1997, which allowed for the development of the AIXM XML Schema. Initial developments were “[[SQL]]-based”, with development moving to XML in 1999. The first version of the schema was released in 1999 as AICM/AIXM 2.1 with further development leading to an updated version, AICM/AIXM 3.3 in 2002. This then allowed the EAD to begin operations in 2003.<ref name=":0">{{Cite book|title=Introduction to AIM, AICM and AIXM|publisher=EUROCONTROL|year=2006}}</ref>
After this, EUROCONTROL began a partnership with the FAA and the US National Geospatial Intelligence Agency in order to further develop AIXM for international usage and cover global civilian and military needs. The AIXM Change Control Board (ACCB) was set up to allow for international states and industries to participate in the development of AIXM. In 2004 AIXM 4.0 was released with an update (4.5) in 2005 which was the first version to incorporate suggestions from the ACCB and the international community.<ref name=":0" />
Version 5.0 was developed through a public design review meeting at the 2006 Global AIM Congress. AIXM 5.0 aligned the format with current ISO standards for geospatial information, including GML, allowed for modular development and future extension and was also the first version to enable [[Digital Notam|digital NOTAM]]. This version is still in use by some “early adopters” including the FAA.<ref>{{Cite web|url=http://www.aixm.aero/page/aixm-50|title=AIXM 5.0 {{!}} AIXM|website=www.aixm.aero|language=en|access-date=2017-03-15}}</ref>
== AIXM Viewers ==
Whilst AIXM does use GML standards, it cannot be viewed with standard GML viewers as aeronautical data requires specialised processing. EUROCONTROL and the FAA maintain a list of AIXM viewers developed by EUROCONTROL, Luciad and Snowflake Software (now part of Cirium).<ref>{{Cite web|url=http://www.aixm.aero/page/free-aixm-viewers|title=Free AIXM Viewers {{!}} AIXM|website=www.aixm.aero|language=en|access-date=2017-03-15}}</ref> EUROCONTROL also maintains a list of free sample data that can be used with these viewers.<ref>{{Cite web|url=https://ext.eurocontrol.int/aixmwiki_public/bin/view/Main/XML_Tags#H5BSample5DESRI28oldDAFIFData29|title=AIXM 5.1 - Data sources (XML) (Main.XML_Tags) - XWiki|last=POROSNICU|first=EDUARD|website=ext.eurocontrol.int|language=en|access-date=2017-03-15|archive-date=2017-03-16|archive-url=https://web.archive.org/web/20170316025348/https://ext.eurocontrol.int/aixmwiki_public/bin/view/Main/XML_Tags#H5BSample5DESRI28oldDAFIFData29|url-status=dead}}</ref>
