# Additional Metadata Support for Entries

Metadata provides supplementary information about an [entry](/docs/content-managers/author-content/about-entries), aiding in its management and classification. By default, when you create a new entry in Contentstack, certain metadata is automatically added, including:

*   Entry name
*   Localization status
*   Publishing status
*   Last modification date and time
*   Content types in which the entry has been referenced

To enhance content management, Contentstack allows the addition of custom metadata to entries [via the Metadata for Entries and Assets API Request](/docs/developers/apis/content-management-api#metadata-for-entries-and-assets) without incrementing their versions. This feature facilitates better organization and categorization of entries, making it easier to search for specific content within a content type.

## Adding Custom Metadata via API

Custom metadata can be added to entries using the Content Management API. This process does not increment the entry's version, ensuring version control remains intact.

**Note**: The metadata size allowed per extension per entry/asset is 5KB. Ensure that the metadata added complies with this limitation. For more information, refer to the [Additional Metadata Support for Entries documentation](/docs/content-managers/working-with-entries/additional-metadata-support-for-entries).

### Examples of Custom Metadata

Here are some examples of custom metadata that can be added to entries:

*   **Entry type**: Indicates whether the entry is a parent or a referenced entry.
*   **Owner details**: Information about the entry owner
*   **SEO tags**: Generic SEO tags to improve search engine optimization.
*   **Entry categorization**: Taxonomy-based classifications to group entries effectively.
*   **Custom tags or labels**: User-defined tags or labels for better organization.

**Additional Resource:** Contentstack also allows you to add custom metadata for your assets. Refer to the [Additional Metadata Support for Assets](/docs/content-managers/author-content/additional-metadata-support-for-assets) documentation to learn more about it.
