=== Subject ===
A [[Subject Object|subject]] is a [[#Data object|data object]] that stores a node for the [[#Subject tree|subject tree]] of an [[#Archive|archive]].  

A subject has three separate [[#Metadata field|metadata fields]] to describe the value it represents:
* '''ID''' - A short text string providing the unique ID for that subject.
* '''Name''' - The human-readable name for that subject.
* '''Sort value''' - The value used to determine the ordering of the subject amongst its siblings in the subject tree (e.g. in a [[#Browse view|browse view]]).

A subject also contains a '''parent''' metadata field that links it into the rest of the subject tree and a '''depositable''' metadata field that indicate whether it is an option that can be selected when the subject tree or part thereof is used to provide a metadata field for another data object (e.g. [[#EPrint|eprint]]).
