03 Hierarchies of the Subclasses of Editorial Object

EditorialObject is one of the most important classes. It can be subclassed to more specific classes like Programmes, Posts, Items, Scenes, Series. The subclasses inherit the set of properties from their superclass(es). Most often, they add properties that differentiate them from their ancestors. And often these properties are object properties that relate them to other subclasses of EditorialOjects.

For example: a Serial is a subclass of EditorialGroup, which is a subclass of EditorialObject. The Serial inherits the attribute "hasContributor" from EditorialObject. Also, a Programme is a subclass of EditorialWork, which is a subclass of EditorialObject. The Programme inherits the attribute "hasContributor" from EditorialObject. Furthermore, the Programme adds the property "isEpisodeOf" pointing to EditorialGroup.
