4.2.3. Content objects
We have now looked at the content class, its attributes and their datatypes. This section
describes the content object.
Recall that:
• In programming terms, a content object is an instance of a content class.
• While the content class defines the type and structure of the data, it is the content object
that actually stores the data.
• Inside a content object, all data is stored in one or more content object attributes.
The following illustration summarizes and shows the relation between datatypes, attributes,
content classes and content objects. The content objects are instances of the same content
class, which means that they are of the same type but contain different data.
