# Metadata enforcement rules for publishing


The metadata enforcement rules for publishing in Amazon DataZone strengthen data governance by enabling domain unit owners to establish clear metadata requirements for data producers, streamlining access requests and enhancing data governance.

The feature is supported in all the AWS commercial Regions where Amazon DataZone is currently available.

Domain unit owners can can complete the following procedure to configure metadata enforcement in Amazon DataZone:

1. Navigate to the Amazon DataZone data portal using the data portal URL and log in using your SSO or AWS credentials. If you’re an Amazon DataZone administrator, you can obtain the data portal URL by accessing the Amazon DataZone console at https://console.aws.amazon.com/datazone in the AWS account where the Amazon DataZone domain was created.

1. Choose **Domains**, navigate to the **Domain units** tab and choose the domain unit that you want to work with.

1. Choose the **Rules** tab and then choose **Add**.

1. On the **Create required metadata form rule** page, do the following and then choose **Add rule**:
   + Specify a name for your rule.
   + Under **Action**, choose **Data asset and product publishing**.
   + Under **Required forms**, choose **Add metadata form**, choose a metadata form within the domain / domain unit that you want to add to this rule, and then choose **Add**. You can add up to 5 metadata forms per rule.
   + Under **Scope**, specify with which data entities you want to associate these forms. You can choose data products and/or data assets.
   + Under **Data asset types**, specify whether the rule applies across all asset types or limit it to selected asset types. 
   + Under **Projects**, specify whether the required forms will be associated with data products and/or assets published by all projects or only selected projects in this domain unit. Also, check **Cascade rule to child domain units** if you want child domain units to inherit this requirement.
