DSpace Items

The functionality is largely inspired by the SOLR official de-duplication approach, for each item one or more signatures are computed using pluggable implementation. 

...

  • During the submission and the workflow, the potential duplicates are presented and feedback from the submitter and validator are collected (see deduplication alert)
  • An administrative dashboard is available to the administrator to check for existent duplicates and merge group of items (see The administrative UI)

CRIS Objects

Info
Since DSpace-CRIS 5.10

A batch script is provided to merge different instances of a cris object in a single one. The script works on any kind of entity (researcher profiles, organisation units, projects, etc.) with the following rules

  • any items linked to the merged cris object will be linked to the target cris object
  • any cris objects linked to the merged cris object will be linked to the target cris object
  • properties and nested object present only in the merged cris object are copied to the target. The parameters allow fine grain control about which properties copy and override.
usage: ScriptMergeCrisObject
                             
 -d,--delete                   delete merged objects, the default (without
                               the -d option) is to disable them
 -h,--help                     help
 -m,--merge <arg>              CRIS ID(s) to merge into the target (use
                               multuple m if needed - merge occurs
                               respecting the order from left to right)
 -p,--replace_notempty <arg>   properties to override in the target with
                               the values from the merged objects IF NOT
                               EMPTY
 -r,--replace <arg>            properties to override in the target with
                               the values from the merged objects
 -s,--skip                     properties to ignore during the merge
 -t,--target <arg>             CRIS ID to retain (merge target)
 -x,--exclude                  Don't merge properties, only move link from
                               the merged object to the target
