Class DSpaceControlledVocabulary

  • All Implemented Interfaces:
    ChoiceAuthority, HierarchicalAuthority, NameAwarePlugin

    public class DSpaceControlledVocabulary
    extends SelfNamedPlugin
    implements HierarchicalAuthority
    ChoiceAuthority source that reads the hierarchical vocabularies from ${dspace.dir}/config/controlled-vocabularies/*.xml and turns them into autocompleting authorities. Configuration: This MUST be configured as a self-named plugin, e.g.: plugin.selfnamed.org.dspace.content.authority.ChoiceAuthority = \ org.dspace.content.authority.DSpaceControlledVocabulary It AUTOMATICALLY configures a plugin instance for each XML file in the controlled vocabularies directory. The name of the plugin is the basename of the file; e.g., ${dspace.dir}/config/controlled-vocabularies/nsi.xml would generate a plugin called "nsi". Each configured plugin comes with three configuration options: vocabulary.plugin._plugin_.hierarchy.store = <true|false> # Store entire hierarchy along with selected value. Default: TRUE vocabulary.plugin._plugin_.hierarchy.suggest = <true|false> # Display entire hierarchy in the suggestion list. Default: TRUE vocabulary.plugin._plugin_.delimiter = "<string>" # Delimiter to use when building hierarchy strings. Default: "::"

      • storeAuthorityInMetadata

        public boolean storeAuthorityInMetadata()
        Description copied from interface: ChoiceAuthority
        Provide a recommendation to store the authority in the metadata value if available in the in the provided choice(s). Usually ChoiceAuthority should recommend that so the default is true and it only need to be implemented in the unusual scenario
        Specified by:
        storeAuthorityInMetadata in interface ChoiceAuthority
        Returns:
        true if the authority provided in any choice of this authority should be stored in the metadata value

      • getMatches

        public Choices getMatches​(String text,
                                  int start,
                                  int limit,
                                  String locale)
        Description copied from interface: ChoiceAuthority
        Get all values from the authority that match the preferred value. Note that the offering was entered by the user and may contain mixed/incorrect case, whitespace, etc so the plugin should be careful to clean up user data before making comparisons. Value of a "Name" field will be in canonical DSpace person name format, which is "Lastname, Firstname(s)", e.g. "Smith, John Q.". Some authorities with a small set of values may simply return the whole set for any sample value, although it's a good idea to set the defaultSelected index in the Choices instance to the choice, if any, that matches the value.
        Specified by:
        getMatches in interface ChoiceAuthority
        Parameters:
        text - user's value to match
        start - choice at which to start, 0 is first.
        limit - maximum number of choices to return, 0 for no limit.
        locale - explicit localization key if available, or null
        Returns:
        a Choices object (never null).
      • getBestMatch

        public Choices getBestMatch​(String text,
                                    String locale)
        Description copied from interface: ChoiceAuthority
        Get the single "best" match (if any) of a value in the authority to the given user value. The "confidence" element of Choices is expected to be set to a meaningful value about the circumstances of this match. This call is typically used in non-interactive metadata ingest where there is no interactive agent to choose from among options.
        Specified by:
        getBestMatch in interface ChoiceAuthority
        Parameters:
        text - user's value to match
        locale - explicit localization key if available, or null
        Returns:
        a Choices object (never null) with 1 or 0 values.
      • getLabel

        public String getLabel​(String key,
                               String locale)
        Description copied from interface: ChoiceAuthority
        Get the canonical user-visible "label" (i.e. short descriptive text) for a key in the authority. Can be localized given the implicit or explicit locale specification. This may get called many times while populating a Web page so it should be implemented as efficiently as possible.
        Specified by:
        getLabel in interface ChoiceAuthority
        Parameters:
        key - authority key known to this authority.
        locale - explicit localization key if available, or null
        Returns:
        descriptive label - should always return something, never null.
      • getValue

        public String getValue​(String key,
                               String locale)
        Description copied from interface: ChoiceAuthority
        Get the canonical value to store for a key in the authority. Can be localized given the implicit or explicit locale specification.
        Specified by:
        getValue in interface ChoiceAuthority
        Parameters:
        key - authority key known to this authority.
        locale - explicit localization key if available, or null
        Returns:
        value to store - should always return something, never null.
