Class of all Items (foundation class) Title of this Item
Item_Class Name of this Item
This category item is the foundation for the hierarchy of items that represent "classes." A class is an item, some of whose properties make statements about the other items that are "instances" of that class. Wontologies can be constructed where the membership (set of instances) in the class are determined by rules that compare against the other items in the wontology, but more commonly, a class' instance items are explicitly identified using the is_instance_of property. Any item that is to represent a "class" (a category whose child items are "instances" of the class) should be identified as a child of this category or one of this category's other children using the sub_class_of property.
