Bulk Asset Management in AEM DAM - Feasibility Check

[Neel_Mehta]

Hi All,

I wanted to check if the following actions can be performed for a large volume of assets in AEM DAM, and what possible methods or tools (APIs, GenAI, scripts, etc.) we can use to achieve them:

1. Bulk Rename Assets – Is there a way to change file names in bulk, either through AEM APIs, scripts, or using GenAI-based logic (e.g., metadata-driven naming)?

2. Reorganize Folder Structure – Can we move assets across folders or restructure the DAM in bulk through automation?

3. Identify Duplicate Assets – Is there a reliable way to detect and report duplicate assets (based on content, metadata, checksum, etc.)?

Appreciate your inputs on what's feasible within AEM's native capabilities or if any custom approach is recommended.

Best regards,

Bulk Rename Assets – AEM Assets HTTP API or JCR API : Use scripting (e.g., Groovy, Sling servlets) to traverse assets and rename them
Reorganize Folder Structure- 

• JCR API: Move assets across folders using session.move(). 
• AssetManager API: AssetManager assetManager = resolver.adaptTo(AssetManager.class);
  assetManager.moveAsset("/content/dam/old-path/asset.jpg", "/content/dam/new-path/asset.jpg");

Hi @Neel_Mehta,

Technically, yes—it is possible for all the scenarios you mentioned. However, there is no built-in UI console to achieve this through button clicks.

You'll need to use one of the following methods:

• Asset APIs (https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/assets/admin/mac...)

• A custom servlet that handles your use case using the DAM and AssetManager APIs

• Groovy scripts tailored to your specific scenario

Thank you,

Hi @Neel_Mehta ,

These are some ways to  perform actions for a large volume of assets in AEM DAM - 

1. Bulk Rename Assets

    1. Use the AEM Assets HTTP API (/api/assets) or Sling POST as a servlet.

    2. Or run a Groovy Console or custom servlet that:

• Reads metadata (dc:title, jcr:created).
• Generates names (optionally via GenAI model).
• Executes ResourceResolver.move() or Session.move().

2. Reorganize Folder Structure:- Use Groovy Console or custom Java/Groovy script employing ResourceResolver.move() or Sling POST with :dest

3. Identify Duplicate Assets

1. Leverage checksum deduplication: read jcr:content/metadata/dam:sha1 via QueryBuilder or JCR SQL2.
2. Group assets by identical SHA‑1 values—these are duplicates 

Process:

• Query all assets and retrieve dam:sha1.
• Aggregate and identify duplicates.
• Report or remove based on matches.
