Managing MetaClass Sensitivity and Reading Access Areas
*The attribute enabling configuration of MetaClass sensitivity is accessible only if you have the MEGA Supervisor technical module.
In the reading access management frame:
• a user is connected to a reading access area that defines all the objects he/she can see.
*See "Connecting Users to Reading Access Areas".
• an object type (MetaClass) is characterized by its sensitivity.
A MetaClass can be of sensitivity:
• standard (default value)
Occurrences of the MetaClass created by a user belong to the user reading access at creation area or the Standard reading access area if the user does not have a reading access at creation area.
• High
Occurrences of the MetaClass created by a user belong to the reading access area of the user that creates them.
*To modify the sensitivity of a MetaClass, you must have rights to modify MEGA data. The option "Authorize MEGA Data Modification" must be activated at environment level, see "Managing Options", page 365.
You can modify sensitivity value of the MetaClass.
*See "Modifying MetaClass sensitivity".
*By default, a MetaClass is Standard sensitivity.
Opening the MEGA MetaClasses reading access configuration dialog box
To open the MEGA MetaClasses reading access configuration dialog box:
1. From MEGA Administration, connect to the environment concerned.
*See "Connecting to an Environment", page 5.
2. Expand the User Management folder.
3. Right-click the Data Reading Access folder and select Configure MEGA MetaClasses for reading access.
The MEGA MetaClasses Reading Access Configuration dialog box appears, listing the available MetaClasses.
The icon alongside the name of each MetaClass indicates that default values:
• have been modified
• are retained.
Modifying MetaClass sensitivity
To modify MetaClass sensitivity:
1. Open the MEGA MetaClasses reading access configuration dialog box.
*See "Opening the MEGA MetaClasses reading access configuration dialog box".
2. In the list of MetaClasses, select the desired MetaClass.
3. In the right pane, select the MetaClass sensitivity value:
*A red cross alongside the name of the MetaClass indicates that at least one attribute of the MetaClass has no longer its default value.
4. Click OK.
*Modifications carried out may be canceled when your environment is updated. Remember to back up your extensions (metamodel and technical data).
Hiding confidential or sensitive objects in a diagram
So as not to distort a diagram, confidential or sensitive objects are visible by default.
To hide confidential or sensitive objects in a diagram:
1. Open the MEGA MetaClasses reading access configuration dialog box.
*See "Opening the MEGA MetaClasses reading access configuration dialog box".
2. In the list of MetaClasses, select the desired object.
3. In the right pane, in the Confidential objects display in diagrams box, select "Confidential objects are hidden".
*A red cross alongside the name of the MetaClass indicates that the MetaClass default value has been modified.
4. Click OK.
*These modifications are not taken into account in the metamodel until the metamodel is compiled. Compile the metamodel before closing the MEGA Administration module, see "Compiling an Environment", page 231.
Objects corresponding to this MetaClass will be hidden in the diagram.
*When you select "Confidential objects are visible", objects corresponding to this MetaClass appear grayed in the diagram and you cannot access information relating to these objects.
*Modifications carried out may be canceled when your environment is updated. Remember to back up your extensions (metamodel and technical data).
