Amazon SageMaker introduces metadata rules to enforce standards and improve data governance

[The next generation of SageMaker](https://aws.amazon.com/sagemaker/) brings together widely adopted AWS machine learning and analytics capabilities, delivering an integrated experience with unified access to all data. Amazon SageMaker Lakehouse supports unified data access, and Amazon SageMaker Catalog, built on Amazon DataZone, offers catalog and governance features to meet enterprise security needs. Amazon SageMaker Catalog now supports metadata rules, allowing organizations to enforce metadata standards across data publishing and subscription workflows. By standardizing metadata practices, organizations can improve compliance, enhance audit readiness, and streamline access workflows for greater efficiency and control. With metadata rules, domain owners can define mandatory metadata fields that data users must complete when publishing assets to the catalog or requesting access to data. For example, a financial services organization can require producers to classify data before publication, and consumers to provide project details and compliance evidence as part of an access request. Healthcare providers can use metadata rules to enforce metadata standards to align with patient data regulations. Metadata rules also enable the creation of custom approval workflows for subscriptions to assets, using collected metadata to facilitate access decisions or auto-fulfillment—outside of Amazon SageMaker.
