Creating an item in the dictionary
Most items can be directly scoped to a Package or the Model. For example, Actors and Use Cases.
Some items have to be child items of another item type. For example, A Column must be a child item of a Table. You must create child items through the parent item.
Some link items are a child of two parent items. For example, an Association is a child of the two items it links. These link items must be created through diagrams.
