# Support metafield and metaobject standards in Declarative Custom Data Definitions

We now support enabling and referencing standard metafield and metaobject definitions through an app’s TOML file. Key benefits include:

* Standard metafield and metaobject definitions can be enabled through TOML, and managed through the [app dev](https://shopify.dev/docs/apps/build/cli-for-apps/test-apps-locally) or [app deploy](https://shopify.dev/docs/apps/launch/deployment/deploy-app-versions) command.
* Shopify automatically distributes these definitions to multiple shops simultaneously, significantly speeding up migration processes.
* Updates are atomic, ensuring that all stores consistently maintain the same version of your definitions.

For more information, see the [custom data documentation](https://shopify.dev/docs/apps/build/custom-data) on shopify.dev.
