Classes receive default security initially from their parent class.
Administration Console for Content Platform Engine displays all available classes in its Class node and Other Classes node. The administrator can define any number of new subclasses of most of these classes and can edit the access rights of any class.
When you use Administration Console for Content Platform Engine to display the properties of a document class, you see three security-related tabs:
Content Platform Engine provides the Document Class which you can modify and use as the start of your own hierarchy of document classes. For example, you could create this hierarchy of document classes:
Document Class (predefined, can be modified)
Tax Bills (subclass of Document Class)
Property Tax Bills (subclass of Tax Bills)
Estate Tax Bills (subclass of Tax Bills)
Each document class receives its default security from its document class parent. Subsequent updates to a parent class propagate to the child classes.
The Default Instance Security collection of permissions on a document class provides the initial security for a new document based on that class. Similarly with folders and every other class that allows you to create instances of it. This initial security is not treated as Inherited and is therefore editable. Modifying a class does not affect the security of existing objects based on that class.
