# Updating Asset Details

{% hint style="info" %}
This page covers updating asset details through the UI, one asset at a time. To update metadata for many assets at once, use [Export/Import](/export-import/export-import-overview.md). To update asset details programmatically, use the [Assets API](/public-api/overview/index/assets.md).
{% endhint %}

The Asset Details page is where you maintain the metadata that makes an asset trustworthy and discoverable: description, owners, business owners, custom attributes, linked glossary terms, and column-level classifications. This page walks through updating that information from both the Overview tab and the Schema tab.

## Updating the Overview tab

{% hint style="info" %}
You need Edit access for the asset (granted through the "Asset Details" policy) to make changes. [Learn about source-based policies.](/group-access-policies/source-based-policies.md)
{% endhint %}

The Overview tab shows the asset's description, owners, business owners, ratings, column classifications, linked data products, and linked glossary terms, along with the full list of columns in the table.

1. Open the asset and select the **Overview** tab to review its current description, owners, business owners, and attributes.

### Adding a custom attribute

1. Select **Update custom attributes**. A dropdown lists the custom attributes available for this asset — select the ones you want to assign.
2. Enter a value for each selected attribute, then click **Save preferences**. The new attribute value appears immediately in the list.

For the full range of supported attribute types and who can apply them, see [Applying custom attributes to catalog assets](/catalog/data-catalog/apply-custom-attributes.md).

## Updating column-level details in the Schema tab

The Schema tab lists every column in the table and lets you set classifications, linked terms, descriptions, and custom attributes at the column level.

1. Switch to the **Schema** tab.
2. Click the column you want to edit and add or update its classification, linked terms, description, or custom attributes.

For classification-specific steps, see [Add classifications to fields](/catalog/data-catalog/add-classifications-to-fields.md).

## Submitting your changes

1. Once your edits are complete, click **Request changes** and review the summary.
2. Select a reviewer, or check **Mark as approved immediately** if you have the necessary permissions, then click **Confirm and request changes**.

Depending on your access controls, the change either applies immediately or goes to the selected reviewer for approval. For more on how approvals work, see [Initiate a change request](/approval-workflow/summary-of-approval-workflow/initiate-a-change-request.md).

Keeping the Overview and Schema details current on every asset makes your data catalog easier to trust, search, and govern across your team.
