6.5 Showing Packageable Elements on a Package Diagram

In addition to packages, package diagrams are used to show packageable elements. Packageable elements are normally represented by node symbols of various shapes and sizes, although icons can also be used.

The package diagram in Figure 6.5 shows more detail of the Components package from Figure 6.2, which is a model library that contains off-the-shelf components intended for use in building cameras and surveillance systems. The components are blocks, as indicated by the «block» keyword, and are shown within the diagram frame that represents the Components model library. The diagram only shows some of the model elements within the model library to reduce clutter. As explained in Chapters 2 and 5, diagrams are simply views of the underlying model and may not show all possible contents that can appear on the diagram. The diagram name is also elided, but could have been included to highlight the diagram purpose.
