5.1. Taxonomy
The E2 system is built around the ECCAIRS taxonomy, constituted by ADREP taxonomy + ECCAIRS/EU specific taxonomy. While most of it is centrally maintained, in accordance with specific governance through the NA’s established Data and Quality Working Group, there is also the possibility for Authorities to maintain their own custom taxonomy, which allows them to adapt their usage of E2 to their own processes.
The taxonomy browser is a portal of the E2 System that provides detailed information of all the ECCAIRS taxonomy structures, entities, attributes and value lists in an easy-to-use UI.
The taxonomy browser is only for consulting purposes.
The Officer has to access the taxonomy menu to access the central or custom taxonomy for the Officer’s Authority. See the List of taxonomies section for further details.
The Taxonomy tree and the search bar are displayed on the left side of the screen. They can be hidden by clicking on the 'arrow' icon. The left panel is resizable by clicking on the 3-dot menu and moving it to the left or the right.
