Configuring Controlled Vocabularies
DSpace now supports controlled vocabularies to confine the set of keywords that users can use while describing items. The need for a limited set of keywords is important since it eliminates the ambiguity of a free description system, consequently simplifying the task of finding specific items of information. The controlled vocabulary allows the user to choose from a defined set of keywords organized in an tree (taxonomy) and then use these keywords to describe items while they are being submitted.

<input-type>onebox</input-type>will display a onebox style field (optionally repeatable) which pops up the entire hierarchical vocabulary to allow you to select an individual term.
<input-type>tag</input-type>will display a tag-style field (optionally repeatable) which suggests terms within the vocabulary as you type.
The following vocabularies are currently available by default:
