I need to find all the duplicated assets in DAM.

I followed https://docs.adobe.com/docs/en/aem/6-2/author/assets/managing-assets-touch-ui/duplicate-detection.html

This document is not helping me in searching for all duplicate values. Also, it doesn't tell that i am uploading a duplicate asset. It just pops-up a window asking for replacing or create new version for that asset.

My priority is to get list of all duplicated DAM assets. Please advise

Thanks in advance. enter image description here

  • Hi, I tried uploading an image asset in Touch UI and it seems Duplicate-Detection working there. I got a pop-up window telling me that duplicates values are present. Could you please tell me how can i generate a report (or a list ) to get all duplicate assets in one go? Thanks in advance – Tarun Prakash Jan 11 '17 at 07:27

AFAIK when you enable the detect duplicate, The behavior will be in the following way.

Touch UI : when you try to upload and then try to Create Version/Replace the asset which is already present. It will populate a popup notating same. Touci UI Duplicate Image Classic UI : It will end up throwing an error with out asking such as Touch UI popup as shown below. I guess Adobe has concentrated only on the Touch UI implementation. Classic UI

When you upload the asset to aem it will create a lot properties for the DAM Assets, one of the property is dam:sha1, The detect duplicate logic will work based on this property value data.

And to get the list of duplicate assets paths you can use a XPATH query

//element(*, dam:Asset)[(jcr:content/metadata/@dam:sha1 = 'ff546dd8055fcfca53471dfa6fe0494c4198e965')]

Where in the "ff546dd8055fcfca53471dfa6fe0494c4198e965" value is of my image dam:sha1 property value. find the below screenshot for reference.enter image description here

  • Not sure if this helps. sha1 value will change if XMP writebacks are enabled so detecting duplicates may not work using dam:sha1 query after that. Just an edge case you should be aware of when implementing above approach. – Imran Saeed Jan 13 '17 at 12:02
  • I think the issue was with AEM 6.0 and 6.1. But when I tested with 6.2, this detect duplicate is working fine. In this way I can detect if the Asset is already present in the DAM or not. But the main query is if I can just detect all DAM duplicate assets which are already there, using SHA values. – Tarun Prakash Feb 03 '17 at 03:07
