4.2. Reference Set Types

This section describes a number of standard reference settypes.

Each reference set type follows a pattern and that pattern is also represented in a machine readable form using a set of Reference Set Descriptor members (known as a Descriptor Template, for short). In most case, the same pattern may be used to define a number of different reference setsto serve a variety of purposes. However, there are also some highly specific reference settypes that exist for a single specified purpose. These are the Reference Set Descriptor Reference Set, Module Dependency Reference Set and Description Format Reference Set.

In each subsection, described a reference settype in under the following subheadings:

The purpose of the reference set;
The format of the reference setmember record is detailed in a table;
The metadata supporting the reference set;
The machine readable reference setdescriptor member records for the reference settype;
Examples of the reference settype;
