The model of the Pier wiki system consists of PRPage objects.
How are the name of a PRPage and the title related?
The name is a unique identifier within its namespace. Think of the
Pier structure as a file-system where everything is a folder. A page
is a folder too, so it can have children. The name would be then the
folder-name.
In the Seaside view the name is used to build the path. Other views
might not need that. The title is something that is displayed in the
user interface. Normally the Seaside view displays the title before
the contents of a page.
A PRPage object may have another PRPage object assigned to it as a local property which describes the environment, i.e. a description how the page has to be displayed.
