Modify metadata asset programatically

Hello,

I am trying to modify metadata/dc:description when I create an asset, but changes does not commited on CRX.

My asset is a PDF and my code:

Asset assetFitxer = assetManager.createAsset(pathDAM, inStream, mimeType, true);
Resource metadataRes = assetFitxer.adaptTo(Resource.class).getChild("jcr:content/metadata");

ModifiableValueMap map = metadataRes.adaptTo(ModifiableValueMap.class);
map.put("dc:description", newCode);
ResourceResolver rs = metadataRes.getResourceResolver();
rs.commit();

--> PDF's file has own metadata and I need to modify dc:description 

If I did commit before to change metadata and after it, changes do not save yet.

 

I think workflow dam asset does not end before I try to change dc:description, so metadata field has original value. 

 

Any suggestions?

Thanks!

can you try like, after creating the asset :

 

AssetManager assetManager = resourceResolver.adaptTo(AssetManager.class);

Asset assetFitxer = assetManager.createAsset(pathDAM, inStream, mimeType, true);

 

resourceResolver.commit();
resourceResolver.refresh();

 

Then get the resource and update/set the dc:description property

    Are you getting any error? or what is happening with the changes? Can you debug and see the output result? or print out the lines failing?

      Hi @abcr1 

      Try below code which I used a while ago. Hope this works for you as well.

      AssetManager assetManager = resourceResolver.adaptTo(AssetManager.class);
      Asset newAsset = assetManager.createAsset(assetPath, is, mimeType, true);
      Node asssetNode = newAsset.adaptTo(Node.class);
      Node jcr_content = (asssetNode != null && asssetNode.hasNode("jcr:content")) ? asssetNode.getNode("jcr:content") : null;
      Node metadata = (jcr_content != null && jcr_content.hasNode("metadata")) ? jcr_content.getNode("metadata") : null;
      metadata.setProperty("dc:description", "value");
      metadata.getSession().save();

          Just to rule out the DAM Update Asset workflow as the root cause of conflict. Can you disable the workflow and try if metadata update is happening ?
