Amazon S3 Metadata and annotations are now available in AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions, giving you the easiest and fastest way to discover, understand, and enrich your S3 data. S3 Metadata automatically captures system-defined details like object size and source, and stores them in Amazon S3 Tables, optimized for near real-time tabular queries that simplify business analytics and real-time inference applications.  
  
Annotations extend S3 Metadata so you can attach rich business context directly to your objects in JSON, XML, or YAML, with up to 1 GB per object. This gives your AI agents and analytics tools the context they need to find and use the right data without building or maintaining separate metadata systems. Annotations share the same durability and consistency properties as the object, move with the object during copy and replication operations, and are removed when the object is deleted. This makes it easy to keep context current as your data evolves.

Annotations are available in all AWS Regions and AWS GovCloud (US) Regions. For a full list of AWS Regions where Amazon S3 Metadata is available, including the annotation table, see the [S3 Metadata AWS Regions](https://docs.aws.amazon.com/AmazonS3/latest/userguide/metadata-tables-restrictions.html#metadata-tables-regions).
