Handling References when you Have Duplicates

When designers are using Asset Link to link to image files in the DAM via InDesign, the DAM is relating it to a duplicate image from a different path when the InDesign file is uploaded to the DAM. We have a current workflow that requires us to create duplicates. I am working on changing that workflow to eliminate the need for the duplicates but we aren't ready yet to do that. So my question is:

 

When files with linked assets are uploaded to the DAM does AEM look for the first asset with that hash to relate it to or does it look for the one originally specified by Asset Link?

As per my understanding Hash is only for duplicate detection, not linking. Linking will still be based on specified Asset Link.

Thanks !

AEM is not resolving those uploaded InDesign references by file hash.
For uploaded .indd files, AEM fetches references by querying repository assets using XMP metadata identifiers — specifically xmpMM:InstanceID and xmpMM:DocumentID. That means the matching behavior is tied to those IDs, not to SHA/hash-based duplicate detection, and not reliably to the original DAM path that Asset Link showed at placement time.

That’s unfortunate. This opens the door to risk. AEM does not manage duplicates well or granular permissioning and governance so its pretty easy for duplicates to work their way into the system. This manner of finding references makes it imperative that you eliminate duplicates or you risk the files referencing a dupe instead of the original. That in turn makes things like rights management extremely challenging.
