Edit Project Dependencies

Editing the project - Descriptor applicability tab

The Descriptor applicability tab serves the administration of dependencies between categorical states and dependent descriptors. First a descriptor has to be selected either by its name in the alphabetically ordered drop down list or its sequence number (“No.”) in the first line of the descriptor dependencies tab. If for the selected project a descriptor tree is present, the  button allows selecting the descriptor form the descriptor tree (see picture below). 

The table Controlling states in the upper left part of the tab shows the categorical states if a categorical descriptor has been selected. When you have adusted the restrichted descriptor view, visible by the button in the toolbar of the Dependent descriptor section, only the actually set dependent descriptors are displayed here. You can switch to an alternate Full descriptorview as described below. For each categorical state Dependent descriptors can be inserted by pressing the button. A dialog window opens to select the descriptor either by its name, sequence number or using the descriptor tree (see picture below).

 

In column “Rule” the symbol indicates that the dependent descriptor is inapplicable if the controlling state is present in a description. The symbol indicates that the controlling state must be present in a description if the controlled descriptor shall be applicable. The rule can be toggled by clicking the symbol in the table or by pressing the corresponding button ( rsp. ) at the right. To remove a dependent descriptor select it and press the button.

In the lower part of the tab you find the States controlling this descriptor. You may double-click on the item to select navigate to it for editing. Alternatively you may edit the controlling descriptor states using the control buttons of the tool strip at the right. By double-clicking an entry in Dependent descriptors or in States controlling this descriptor you may navigate forwards and backwards in the chain of dependent descriptors.

If you want to get an overview of all the project’s descriptor dependencies or want to delete all dependencies, take a look at the Applicability tree section below.

 

 

Calculation of the descriptor applicability

To decide if a descriptor is applicable in a description, the following conditions are evaluated:

  • Inapplicable-if rule: If only controlling states are present in a description, these make the controlled descriptor inapplicable. The character remains applicable if either no state at all, or any non-controlling states are present.
  • Applicable-if rule: If any controlling state is present in a description, these make the controlled descriptor applicable. It is inapplicable if only non-controlling states are present.
  • Special condition 1: If the controlling descriptor is inapplicable (through another applicability rule, or through an explicit “Not applicable” data status value), the controlled descriptor is always inapplicable as well.
  • Special condition 2: If no data for the controlling descriptor are present in a description (data completely missing or only status is “Missing data” or “Not to be recorded”), the controlled descriptor always remains applicable.

 

 

Full descriptor view

By clicking the button in the toolbar of the Dependent descriptor section, you can chenge to the full descriptor view (see image below). In section Dependent descriptors all available project descriptors are shown. You may set a dependency by selecting the descriptor and clicking the button rsp. . To remove the dependency, click on button . Alternatively you may click on they symbol in the table column “Rule” to change the values in the sequence → -> .

If you select a values for the Descriptor tree, the descriptor list is restricted to the values included in that descriptor tree. Please be aware that existing dependencies might be hidden by such a selection! 

You can return to the restricted descriptor view by clicking on button .

 

 

Applicability tree

Instead of the States controlling this descriptor you may display a complete overview of the descriptor applicability rules by pressing the button in the Dependent descriptors section (see image below). By double-clicking an item in the Applicability tree you can open it for editing.

By pressing the button in the Applicability tree section you can delete all dependencies shown in the tree.
