Chapter 10 PowerDesigner Public Metamodel
You can use the Browser to develop or collapse the categories to understand the global structure of the metamodel from a tree view. You can also display diagrams and observe the graphical representation of metadata.
Classes in purple are usually shortcuts of a class existing in another package. The shortcut makes it easier to read the diagram and understand the generalization links between classes. If you want to have an explanation about a purple class in a diagram, you can right-click the class and select Open Related Diagram to display the diagram where the class is actually defined.
The diagram also displays most associations with their roles which makes it possible to identify object collections.
For more information on association roles, see section Associations and collections.
