Meta information is information about your information. It includes information such as the volume's title, copyright notice, and abstract. The abstract is a brief description of the volume's contents.
The Help System uses the meta information to display the title of a help volume and its copyright information. The abstract description is displayed by the desktop Help Viewer in the Front Panel. Other applications capable of displaying help volumes could also make use of this information.
Meta information can also include help topics that are not part of the normal topic hierarchy. Nonhierarchical topics placed in the meta information section are accessed with links.
"Creating Meta Information Topics" shows you how to create a meta information section.
