Taxonomy structure

ECCAIRS taxonomy elements are structured as follows:

  • Entities 

  • Attributes

  • Value Lists

  • Values

Entities

Entities represent items to which specific attributes are assigned—for example, an “Aircraft” involved in an incident or the associated “Events” description.

Multiple instances of an entity may exist when several items are involved (e.g., multiple aircraft in a single incident).

Entities can have child entities (e.g., an “Engine” belonging to an “Aircraft”).

Entities may also be linked to other entities (e.g., “Airspace” or “Aerodrome” where the “Aircraft” is operating).

Entities information

Entities in the Taxonomy Tree are represented by image.png or image.png.

The following information will be displayed in the right side of the screen when you click on an Entity in the Taxonomy Tree:

  • Entity information: A brief summary of the selected Entity.

  • Parent Entities: The list of its parent Entities

  • Child Entities: The list of its children Entities

  • Attributes. The list of its Attributes

Click on each tab (Parent Entities, Child Entities, Attributes) to view its information.

Attributes

Attributes describe properties/values associated to an entity and represented by image.png. An example of an attribute of the “Aircraft” entity is its "manufacturer/model". Attributes may have either single or multiple values and can be of the following types:

  • Number

  • Date

  • Time

  • DateTime

  • Longitude

Attribute information may be displayed across two tabs:

  • Definition

  • Values: If the attribute has a predefined value list, you can navigate through the values in the Values Tree by clicking on each element. The selected value will display its definition. Values can be searched by Taxonomy Code or Description and can be sorted alphabetically.
