UML to XSD – AIXM 5.1 mapping scripts 10 AIXM 5.1 Mapping Rules - Features AIXM is based on GML AIXM Features are GML features… AIXM follows the GML object-property concept.

UML to XSD – AIXM 5.1 mapping scripts 11 AIXM 5.1 Mapping Rules - Features For each AIXM Feature in the UML, the following XML schema entities are created: FeaturePropertyType Feature FeatureType FeatureTimeSlicePropertyType FeatureTimeSlice FeatureTimeSliceType FeaturePropertyGroup AIXM objects are encoded as GML objects. The mapping rule for Objects are the same as the rules for Features except that Object do not exist outside of a feature TimeSlice types and elements are not created

UML to XSD – AIXM 5.1 mapping scripts 24 UML Extension A feature or object may be extended by creating a class with the same name as the core AIXM feature and giving it a stereotype >. New classes (features and objects), that do not extend existing AIXM Core classes, can be also created.
