ISAN application Deduplication

Principle

After the submission of the application form, the ISAN system performs a duplicate check to assess if an ISAN has already been allocated for the work. If a similar registration is found in the ISAN registry, then the ISAN application is paused. A manual deduplication review is required:

• If the ISAN is already allocated, then the existing ISAN is to be used.
• If none of the potential duplicate(s) corresponds to the submitted work, then a new ISAN is allocated.

Deduplication review

1.    Open the deduplication screen

• From the list of pending applications for deduplication or
• From the Registration Timeline after the submission of the application

Click on Deduplicate to display the deduplication screen:

The left part of the screen displays your application, the right part displays the list of potential duplicates (one work in the above example) 

2.    Click on a potential duplicate (right side list)

This displays a side by side view of submitted data and the selected potential duplicate data

3.    Compare the metadata

The colors highlight the similarities (green) and the differences (red)

4.    Confirm or reject the potential duplicate

You can take an individual decision for every potential duplicate (right side menu icons) or confirm that your application is different from all potential duplicates to issue the ISAN (left side menu)

• Take a decision for the potential duplicate with the help of the menu icons above the potential duplicate (right part of the screen)

	The two works are different: reject the duplicate
	The potential duplicate is a different work that is linked to your application (e.g. two parts of the same sequel). Confirm your application as a New Work to issue a new ISAN + link this ISAN to the potential duplicate.
	return to the list of potential duplicates
	reject this duplicate
	Display the previous / next potential duplicate data

• Take a decision for your application: If none of the potential duplicate is the same work as your application, select in the left side menu +Action the option New Work to issue a new ISAN for your work.

Is New ISAN	None of the duplicate candidates correspond to the application. A new ISAN will be issued.
Is Missed Duplicate	You are sure that my application is a Duplicate, but you can’t find the duplicate ISAN in the list of duplicates (e.g. removed accidently from the list with the aboveaction). This will open a search window to find and select the duplicate ISAN.
Is Duplicate & Assign to Me	The application is duplicate with an existing ISAN registered by someone else, but you are the producer of the work. This action is only available (active) if the ISAN has been pre-registered by a trusted third party, i.e. not a producer that needed the ISAN or a version of it before your application. If you are the producer of the work, you can reassign the ISAN in your catalogue. This operation will be invoiced as a registration.

5.    Retrieve the ISAN

 Once you have confirmed that your application is either a new work or a duplicate with an existing ISAN, you can retrieve the ISAN for your application in the list My ISAN (menu New ISAN / My ISAN)

• The column Application Result displays
  • New ISAN if a new ISAN was issued
  • Existing ISAN in case of duplicate, the existing ISAN is displayed in the list
• You can view or edit the data anytime from the Action menu at the right of the corresponding line. Note that for an Existing ISAN, View my Application displays the data you have submitted. To display the ISAN data registered in the ISAN registry, you need to click on View Active ISAN in Registration Timeline at the bottom of your application form.
