# Custom Property for a Data Asset
Collate uses a schema-first approach and supports custom properties for all types of data assets. Organizations can extend the default attributes to capture metadata that matters to them — such as business owner, SLA tier, compliance classification, and more.
Custom property values can be viewed and edited from the **Custom Properties** tab on any data asset detail page.
## Creating a Custom Property
1. Click your **Profile** icon in the bottom-left navigation and select **Settings**. Then click **Custom Properties**.
2. Choose the type of data asset you want to define a custom property for — for example, **Database**, **Table**, **Dashboard**, and so on.
3. On the asset type page, click **Add Property**.
4. In the **Add Custom Property** form , fill the following fields:
* **Name** *(required)* — Must start with a lowercase letter in camelCase format. Uppercase letters and numbers are allowed; spaces, underscores, and dots are not.
* **Display Name** — A human-readable label shown on the data asset page.
* **Type** *(required)* — The data type for this property. See [Supported Property Types](#supported-property-types) below.
* **Description** *(required)* — Describe what this property captures to help your team understand its purpose.
5. Click **Create** to save the property.
## Supported Property Types
When adding a custom property, select one of the following types from the **Type** dropdown:

## Adding Values to Custom Properties
After a custom property is defined, you can set its value directly from the data asset detail page:
1. Open any data asset and click the **Custom Properties** tab.
2. Click the **Edit** icon next to the property you want to update.
3. Enter the value and save.
## Edit or Delete Custom Properties
To edit or delete a custom property definition:
1. Click the **Profile** icon and navigate to **Settings** > **Custom Properties**.
2. Select an asset type.
3. In the Actions field, do the following:
* To edit, click the **Edit** icon and update the property's display name, type, or description.
