The Basic Settings Page: MDM Dictionary

The Basic Settings page in the web application and the Basic Properties page in the desktop application are used to set object name, identifier and comment, and to set up MDM dictionary structure. In the desktop application, MDM dictionary structure setup is available only after a dictionary is created.

The checkbox is deselected by default.

To set up dictionary version control, select the Elements can Change in Time checkbox.

After the checkbox is selected, each time a dictionary opens for view in the web application, the Determine Parameter Values dialog box opens, in which one can set the Actuality Date parameter:

After the checkbox is selected, the Dictionary Elements tab will contain the Actuality Date parameter, the list of system attributes will contain attributes that enable element version control. Such dictionary will be named a version one.

After the checkbox is selected, the following options also become available:

Consider Time in Elements' Actual Periods. Selecting the checkbox enables the user to change the type of system attributes INDATE and OUTDATE from Date (the date is represented without time) to DateTime (with time), which affects only the element date type.
Generate Elements' Actual Periods Manually. Selecting the checkbox enables the user to manually set date ranges for version dictionary elements on the Dictionary Elements tab. Otherwise the range is automatically formed as follows: start date is set to the validity date, and end date is set to 31.12.2999.

The checkbox is selected by default.

When the checkbox is selected, the Owner attribute is created automatically.

When the Elements Have Hierarchy checkbox is deselected, the dictionary becomes one-level, that is, a dictionary element cannot have child elements. On an attempt to deselect the checkbox for a dictionary that has at least one child element, a system message informs that this operation is not allowed.

The checkbox is deselected by default.

Select the Translate Dictionary into Other Languages checkbox to create a multilingual MDM dictionary. It stores names of all attributes and values of string attributes both for the current language and for the languages, into which the dictionary is supposed to be used.

After the checkbox is selected, the Translations tab is displayed.

NOTE. Translation of dictionary attributes and elements is available if default language is set for the repository. The default repository language can be selected once: on creating a repository or later in repository settings.

For details about setting up multilingual options of repository contents and system in general, see the Setting Up Multilingual Options section.

The checkbox is deselected by default. The checkbox is available to edit only for outdated MDM dictionary types: MDM dictionaries and composite MDM dictionaries.

GUID (Globally Unique Identifier) is the statistically unique 128 bit identifier. Its main feature is the uniqueness that enables the user to create expandable tools and applications without being afraid of conflicts arising due to duplicate identifiers. Although it is not guaranteed that each GUID is unique, the total number of unique keys is so large (2¹²⁸) that the probability of the same key being generated randomly twice is extremely small.

When the checkbox is selected, another system attribute, Unique Identifier of the string type, is added to the attributes list. This attribute receives a value automatically when elements are added to the dictionary. When this checkbox is selected for a dictionary that already contains elements, the attribute also receives a value automatically.

The checkbox is deselected by default.

To separate discretionary access permissions for MDM dictionary elements:

Make sure that the Use Discretionary Access Control checkbox is selected in the Policies Editor section of the security manager.
Select the Elements have Discretionary Access Permissions checkbox in the dictionary general settings.

After the checkbox is selected, other four mandatory attributes are added to the attributes list of the dictionary that enables the user to set up access permissions for dictionary elements.

The list of access subjects is created on the Access Subjects tab.

NOTE. If the roles of the information security administrator and the application administrator are separated, after selecting the Elements have Discretionary Access Permissions checkbox and saving the dictionary, the checkbox can be deselected only in the security manager. This checkbox can be selected only by the application administrator or the user who has appropriate permissions.

If the policies editor uses discretionary and attribute-based access control methods at the same time, after the checkbox is selected, the Elements have Attribute-Based Access Permissions checkbox becomes available to apply policies and rules of configured attribute-based access control method for each element of MDM dictionary.

The checkbox is deselected by default.

To separate mandatory access permissions for MDM dictionary elements:

Make sure that the Use Mandatory Access Control checkbox is selected in the Policies Editor section of the security manager.
Select the Elements have Mandatory Access Permissions checkbox in the dictionary general settings.

After the checkbox is selected, mandatory access control can be set up for each MDM dictionary element in the Access Permissions dialog box.

The checkbox is deselected by default.

To separate attribute-based access permissions for MDM dictionary elements:

Make sure that the Use Attribute-Based Access Control checkbox is selected in the Policies Editor section of the security manager.
Select the Elements have Attribute-Based Access Permissions checkbox in the dictionary general settings.

After the checkbox is selected, policies and rules of configured attribute-based access control method are applied for each dictionary element.

The checkbox is deselected by default.

When the checkbox is selected, the Hide attribute of the logical type is added to the list of system attributes. By default, this attribute is set to FALSE for dictionary elements. When the attribute is set to TRUE, the element is hidden in the dictionary element tree.

To display all hidden elements, deselect the checkbox.

Tracking other objects that refer to MDM dictionary elements helps sustain integrity of these objects and prevent possible deletion of elements used in these objects. For example, an MDM dictionary element is used in selection of regular report data area. An attempt to delete such an element brings up a warning message that this element is in use and its deletion may violate other objects' integrity.

The list of objects referring to MDM dictionary elements can be viewed in properties of this dictionary. The checkbox is deselected by default, links to elements are not tracked.

The checkbox can be selected only for a composite MDM dictionary. The checkbox is selected by default, the same element can be added an unlimited number of times from the source dictionary to the composite MDM dictionary. When the checkbox is deselected, each element of the source dictionary can be added to the composite MDM dictionary only once.
