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

      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();

        Hi @anudeep_garnepudi , my workflow is external. Conflict with DAM Update Asset workflow is a suggestion mine. My workflow process documents and when I create asset with pdf file I suppose that workflow AEM affects my update on metadata property. I only can modify property after create asset, on same service. Thanks

          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 ?
