Nucleus properties files use several special properties that are indicated by a leading $ character:


The component’s Java class.


The scope of the component (global, session, or request). The default value is global. See the Component Scopes section in this chapter.


A brief description of the component, for display in the ATG Control Center Components task areas.


Given a large number of components in a typical Nucleus application, it can be helpful to document what each component does. You can document your components using the $description property. For instance, you might describe a Person component like this:

$description=Holds name and age traits of users
