Introduction

With DSpace you can describe digital objects such as text files, audio, video or data to facilitate easy retrieval and high quality search results. These descriptions are organized into metadata fields that each have a specific designation.  For example:  dc.title stores the title of an object, while dc.subject is reserved for subject keywords.

You are free to use any application you want to create your controlled vocabularies. A simple text editor should be enough for small projects. Bigger projects will require more complex tools. You may use Protegé to create your taxonomies, save them as OWL and then use a XML Stylesheet (XSLT) to transform your documents to the appropriate format. Future enhancements to this add-on should make it compatible with standard schemas such as OWL or RDF.

Default Hierarchical Controlled Vocabularies

By default, DSpace includes two out-of-the-box hierarchical controlled vocabularies in the [dspace]/config/controlled-vocabularies/ directory. 

• nsi - nsi.xml - The Norwegian Science Index (in the Norweigen language)
• srsc - srsc.xml - Swedish Research Subject Categories (in the English language, with notes in Swedish)

You may create your own hierarchical controlled vocabulary by using either of those as a model.  All valid hierarchical vocabularies should align with the "controlledvocabulary.xsd" schedule available in that same directory.

Enabling / Disabling a Hierarchical Controlled Vocabulary

To enable a hierarchical controlled vocabulary, simply configure it's usage in one (or more) of your fields in your "submission-forms.xml" (as documented below).

To disable a hierarchical controlled vocabulary, simply remove it from all your fields in your "submission-forms.xml".  You can also disable all  controlled vocabularies by commenting out the "DSpaceControlledVocabulary" plugin in "authority.cfg":

plugin.selfnamed.org.dspace.content.authority.ChoiceAuthority = \
 org.dspace.content.authority.DCInputAuthority, \
 org.dspace.content.authority.DSpaceControlledVocabulary

How to invoke a controlled vocabulary from submission-forms.xml

...

The vocabulary element has an optional boolean attribute closed that can be used to force input only with the Javascript of controlled-vocabulary add-on. The default behaviour (i.e. without this attribute) is closed="false". This allows the user to enter values as free text in addition to selecting them from the controlled vocabulary.

The following vocabularies are currently available by default:
