Organization of this DocumentΒΆ
The introduction provides a high level view of the structure of the DDI-4 model, its architecture and the way in which the individual classes are organized. The introduction also provides information on the mechanisms by which the classes are utilized, the relationships among them, how the model can be extended and how it will be managed.
Each Library Package has a diagram showing the relationships between the classes within that Library Package. For each class, information is provided on whether it extends any class, and whether it is based on an existing class in DDI 3.2, GSIM or other standards.

- Examples of the usage of the class and explanatory notes
