Is there a feature, similar to "live copy" for DAM assets? I'm looking for a way to create a parent/child relationship between assets, where the "children" assets inherit from the "parent". We are currently running AEM 5.6.1, but would be interested in new features that may exist on 6.0 or 6.1 as well.
Because of the unique way that AEM stores assets, if you have the exact same file in two locations in the repository, physically only 1 file is stored. The reason being, that each file has a unique SHA1 checksum, the checksum value is used to create a folder/file in the datastore. In this way, you don't duplicate storage for the same file. If the file is modified in any way and uploaded again, only then will a new file in the datastore be created.
However, having a central DAM is always preferable as all instances of an asset will get updated at the same time, otherwise you have to update all nodes that pointed to the original file, which can become inefficient and error prone.
Sounds there is some confusion here. Top contributors like opkar, loki & jorg are saying not there. Example for AEM 6 there is a feature pack "cq-6.0.0-featurepack-5931" & when i looked into aem 6.1 the feature did not go through. I am short of time to investigate & provide exact answer what is going on. Can you please file a support ticket to track this out?
The use case is to support regional variations of a website.
For instance, we're proposing a "global" website structure, which is live-copied to multiple regional structures (ie, "spain", "italy", etc).
The DAM structure would be similar:
company > global > product > asset1
company > italy > product > asset1
company > spain > product > asset1
In many cases the same assets are re-used in multiple regions. So, we'd like to be able to add/update an asset
in 1 global location, and have it copied down to multiple regional locations automatically.
