Can I get the value selected in standard tags in metadata schema?

[Anmol_Bhardwaj]

I want to get the value/values selected by an author when they select a standard tag in metadata schema.

Example: In the custom metadata schema for an asset, I have a tag field, where I have selected /content/cq:tags/test/1

I want to get this value "/content/cq:tags/test/1".

I have to apply this to the metadata field only, as I want to get this value for all the assets, not for a single one.

Here is my use-case:

1. Created a metadata schema.
2. Have added a standard tag field in the form of that schema.
3. Have applied that schema to a folder in my DAM.

Requirement:

• When the user uploads an asset inside that schema, they will have to fill the metadata created.( which includes the standard tag as well ).
• What I want is to get the value/path of the tag which the user will select in that metadata.

Hi @Anmol_Bhardwaj 

Can please you elaborate your question a bit more? What exactly your requirement? 

• This tag field will be visible for all assets?
• If its updated on one assets , it will get added on all assets by default?

this is what you are looking for?

@Anmol_Bhardwaj  If you're programmatically looking to fetch this metadata, you can use below API and getAssetMetadata() method.

https://javadoc.io/doc/com.adobe.aem/aem-sdk-api/latest/com/adobe/granite/asset/api/Asset.html

The metadata is stored on node /jcr:content/metadata of the asset which you can verify in crxde

@shelly-goelThis will only give me the metadata of a single asset right?

As I would be putting the path to a single asset.And need to write a new code or traverse through a lot of (child)nodes to get value for all of them. Which is not feasible in my case.

I need to fetch the value automatically for every asset that the user uploads. Sort of like a listener on the metadata field to get me the value every time.

[shelly-goel]

You can write this logic inside an event listener on node_added event so that everytime an asset is uploaded you get that asset's metadata. Here's the reference: https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-listeners-events/qaq-p...

Thanks. So I would need to put a NODE_ADDED/PROPERTY_ADDED listener to the dam folder and get the value of any new/updated asset from there? Understood. I was actually planning to put another tag field in the schema which will change it's rootPath depending upon the tag selected in the first tag dialog. I have a doubt whether this would work dynamically even before we save the metadata one.Let me try if this will work for that case. Will update here.
