If you assign a user-defined attribute to a POI category (Creating a user-defined attribute), it is automatically applied to all subcategories of this super category. This function is useful if you want to trace or analyze a common feature of POIs in several categories and subcategories.
Example: You create the POI category „education centers“ and assign it the user-defined attribute „number of students“. In this case, you can trace and analyze the number of students of all education centers you defined in the subcategories and POIs of this category.
You can edit a user-defined attribute of POI category only on the level on which you created it.
