Deduplication: the merge tool

Tip

Available, since DSpace-CRIS 5.5.0

The system provides an administrative tool to check the database for potential duplicates and merge the confirmed matches. The tool can be accessed under the administrative menu

Content > Deduplication  (<dspacecris-url>/tools/duplicate)

The system shows a page with multiple tabs:

  • All: in this tab for each configured criteria the system shows the number of groups of potential duplicates that are not yet confirmed / rejected by administrators or librarians (in the workflow)
  • Reported for Merge: in this tab, for each configured, the system shows the number of groups of duplicates that have been reported by the submitter or the librarian
  • Compare: it is possible to manually put a list of itemIDs to compare using the merge tool

The number in the bottom corners represent the groups of potential duplicates remaining after the submitter check, on the left, and the librarian check during the workflow, if any, on the right. See deduplication alert in submission.

 

Clicking on the numbers will lead to the list of potential duplicates
