# Support metafield and metaobject standards in Declarative Custom Data Definitions

DateOctober 31, 2025

FlagsNew

SurfacesTools

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.
