Over the property mapping table of the Extraction Editor work board, the right-button pop-up menu Property has three sub menu items which are used to manage properties. They are:
- Create: is used to create a new property. If a property in the property mapping table has been selected by ticking the top left checkbox, the new created property is inserted before the selected property. Otherwise, it is appended to the end of the mapping table. After this menu item has been clicked, a property editing window pops up, in which not only the property is named but also all attributes can be edited, which is stated in previous chapter.
- Edit: is used to edit a property. If none of the properties is selected, nothing will happen. Otherwise, a property editing window will pop up, where the operator can change both the name and the attributes of the property which is stated in previous chapter.
- Delete: is used to delete one or more properties. The operation should be performed after one or more properties have been selected. Otherwise, nothing is done.
