Amazon SageMaker Unified Studio adds custom asset types to the catalog in IAM-based domains

Amazon SageMaker Unified Studio now supports custom asset types for IAM-based domains. With custom asset types, domain administrators can catalog any format of asset within the SageMaker Unified Studio, such as medical imaging files in Amazon S3, revenue dashboards built in PowerBI, or PDF research reports generated by a third-party platform. Custom asset types bring all assets, regardless of their underlying format, into the SageMaker catalog so teams can search, discover, and subscribe to them without needing separate tools or processes. To get started, an administrator can create a custom asset type with a name, description, and optional metadata forms that define the fields each asset should carry. Individual assets can then be created from that type, enriched with glossary terms and README documentation to add business context for humans and AI agents, and published for discovery. Once published, anyone in the domain can find the asset by name, type, or glossary term and request a subscription through the same governed workflow used for all other catalog assets. Custom asset types for IAM-based domains are available in all AWS Regions where Amazon SageMaker Unified Studio is available.
