How Are Object Properties Inherited?

Properties are object parameters that are used to configure and customize content in the portal. All portal objects have properties. Properties are object-specific, that is they differ from one object to the other. The properties of content objects can be maintained with the Properties editor.

With objects that have a delta link relationship to one another, a target object always inherits the property values from a source object.

When you create an object from another object (for example an iView from an iView template), the values that you define in the source object are copied to the target object.

Additional inheritance rules include:

• Any object can be configured by defining the values that the object should pass to other objects derived from it.

• If the source object of a target object link is changed, the changes are copied to the target object.

• Changes made to the target object have no effect on the original object.

• Certain properties can be overwritten in the target object. Properties for which entries are not possible often contain default values.

• Certain property values cannot be overwritten. This includes, for example, the property CodeLink . You cannot enter values for properties that are read-only.

iView V1 is based on iView template VT1 and takes on all its properties. Two values of these properties are overwritten in V1 . iView V1 is inserted into two roles - R1 and R2 - as a delta link. This results in two new (target) objects V11 and V12 .

All of the properties of V1 are copied to role R1 in V11 and the value of one property is overwritten. All the properties of V1 are copied to role R2 in V12 , and the value of a different property is also overwritten.

iView V1 is a target object in relation to VT1 and a source object in relation to V11 and V12 .
