AIXM version 5 introduces a number of significant changes as compared to the previous versions:
adoption of a number of international standards that maximize the chances for interoperability while also reducing the implementation costs:
GML - Geography Markup Language, a specialization of XML for geographical data - for data encoding
ISO19100 series of geospatial information standards as data modelling framework
UML (Unified Modeling Language) for developing AIXM 5 Conceptual Model
exhaustive metadata incorporation into the model has been identified
update of some concepts (aerodrome mapping, terminal procedures and obstacle data)
new capabilities for the data exchange specification itself:
equal coverage for permanent and temporary data; be able to communicate both ‘permanent’ changes, such as those that occur at AIRAC cycles and temporary situations, typically promulgated through NOTAM; this requires the introduction of an exhaustive temporality concept in the model;
Modularity, extensibility, flexibility of messages and exchange scenarios
Metadata
Integrity
Data Quality Mandates

temporary/permanent changes in the route structure (names/positions of points, etc.);
en-route navaid unserviceability;
airport/heliport usage restrictions;
usage restrictions affecting runway directions, runways, taxiways, gate/stands, TLOFs, etc;
changes in the surface characteristics of runways;
threshold displacements;
new permanent or temporary obstacles (point/line/polygon are supported).
