# Cosmo Delete Asset Metadata Action

The **Cosmo Delete Asset Metadata Action** node removes one or more custom metadata entries from an asset in Cosmo.

Unlike the [Cosmo Change Asset Metadata Action](/helmut4-releases/helmut4-components/streamdesigner/nodes/actions/cosmo-16/cosmo-change-asset-metadata-action.md), which adds or updates metadata, this node deletes specific metadata fields by their key names from an already indexed asset.

The node targets the asset using its **Asset ID** and removes the specified keys from the `customMetadata` array in the database.

If a specified metadata key does not exist, the node ignores it and continues successfully without failing.

{% hint style="info" %}

#### Important Timing Note

Avoid executing this node immediately after [Cosmo Add Asset to Project Action.](/helmut4-releases/helmut4-components/streamdesigner/nodes/actions/cosmo-16/cosmo-add-asset-to-project-action.md)\
The asset may not yet be fully available in the database. If both nodes are used in the same stream, insert a [Sleep node](/helmut4-releases/helmut4-components/streamdesigner/nodes/actions/misc-21/sleep-action.md) between them (recommended delay: **at least 4000 ms**).
{% endhint %}

#### Input Parameters

**Asset ID**\
Database ID of the asset from which metadata should be removed.\
Typically retrieved using `{job.assetId}`.

**Metadata Keys**\
List of metadata keys to delete from the asset.

#### Behavior

* Deletes only custom metadata (not system metadata)
* Ignores non-existing keys
* Does not modify the media file
* Updates only the Cosmo database
* Supports asynchronous execution

#### Typical Use Cases

* removing temporary workflow flags (e.g., “QC\_PENDING”)
* clearing ingest or transfer identifiers
* resetting approval or review states
* cleaning metadata before archiving or delivery

#### Practical Note

Think of this node as a **metadata cleanup tool**.\
After automation workflows add tags to drive processing (QC, publishing, transfer, etc.), this node lets you remove those flags once the workflow is complete so the asset returns to a clean state.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.helmut.de/helmut4-releases/helmut4-components/streamdesigner/nodes/actions/cosmo-16/cosmo-delete-asset-metadata-action.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
