The temporal aspect can be informally described as the “when”, whereas the content aspect can be described as the “what”. A lifecycle diagram always shows the temporal aspect of a method; the content aspect can, optionally, be shown as well.
The elements that appear inside a lifecycle diagram are stage kinds and process kinds. Topological containment is extensively used to depict temporal framing, such as a process being performed within a phase or a phase occurring within a time cycle. Generic links are used to join stages inside a common container.
Consider the example shown in Figure 20 (see the colour plate section). A time cycle kind named “OPEN/Metis Project” is introduced. It contains ...
