Additional Metadata Support for Assets

Metadata is the data that provides additional information about an asset. This metadata aids asset management and classification.

When you upload an asset, Contentstack adds some basic metadata by default, such as:

  • Name of the asset
  • Last modification time and date of the asset
  • File size of the asset
  • Location of the asset in the repository (asset folder)
  • Content types in which the asset has been referenced

However, with constantly growing content requirements, you may need to add customized metadata for efficient content management.

This is where “Additional Metadata Support” comes into play.

Contentstack lets you add additional, custom metadata to your assets (via the API) without incrementing their versions. Additional metadata helps content managers facilitate better organization or categorization of assets and aids easy search.

Note: Whenever you create metadata for an asset using the API, you need to specify the extension to which it will be connected. The maximum metadata size allowed per extension is 5 KB (includes metadata defined for all entries and assets associated with a specific extension).

You can add additional metadata only via API (not through the UI), using the Metadata Content Management API requests.

Some examples of additional metadata that you can add are:

  • Asset type (image, video, audio clip, or document)
  • Owner details for an asset
  • Generic SEO tags
  • Copyrights for an image or document
  • Custom asset tags or labels

Additional Resource: Contentstack also allows you to add custom metadata for your entries. Refer to the Additional Metadata Support for Entries documentation to learn more about it.

This plan-based feature will be available only in the new Contentstack interface. For more information, you can reach out to our Support team.
