  1. AIXM 5 UML Modelling Conventions

  2. AIXM is GML • AIXM is an XML exchange standard based on a subset of GML. Essentially: • AIXM Features are GML features • AIXM Objects are GML objects • AIXM follows the GML object-property concept

  3. Diagrams • Model uses: • Class diagrams • features, properties, relationships and inheritance between features • Package diagrams • split the model into modules and identify dependencies among sets of classes.

  4. Stereotypes • Stereotypes are used to further define and extend standard UML concepts. • <<feature>> • <<object>> • <<choice>> • <<datatype>> • <<enumeration>> • <<codelist>>

  5. Abstract Classes • Abstract classes are designated by putting the class name in italics. • An abstract class cannot be realised in an implementation such as an XML document • Abstract classes are used as base classes in an inheritance hierarchy.

  6. Features stereotype • Real World • Fundamental objects • Change in time

  7. Objects • The object has its own attributes that are reused throughout the model • A property has a multiplicity greater than one

  8. Choice • Used to model XOR relationships

  9. DataTypes • Datatypes are used throughout the model • <<datatype>> – basic data type that specifies a pattern to use • <<enumeration>> – a fixed list of values • <<codelist>> – similar to an enumeration but the list can be expanded

  10. Properties - Attributes Simple Properties • Attributes are used to describe simple properties of a feature or object

  11. Properties - Relationships • Relationships are used to describe associations to features or objects • Uni-directional association used when the relationship refers to a feature • Relationships to objects are depicted by the standard UML composition

  12. Properties - Relationships • Standard UML association class is used to describe attributes about the relationship

  13. Properties - Inheritance • Inheritance - The specialized feature inherits all of the properties of the more general feature

  14. Naming Conventions • Feature, Object and Choice names are written in UpperCamelCase e.g. NavaidEquipment • Simple property names (i.e. attributes) are written in lowerCamelCase e.g. widthShoulder • Relationship names are written in lowerCamelCase but as present tense verbs e.g. isSituatedAt • Datatype names are written in UpperCamelCase and end with ‘Type’ e.g. CodeAircraftType
