AWS s3 (Simple Storage Service) is one of the simplest Amazon Web Service. It works just like a network drive. Amazon has granted many public institutions free S3 buckets. Smithsonian Institute (SI) is one of them. With its open access initiative, SI also shared a large amount of data on s3.
The data largely contain metadata at SI, 3D models, and pictures. To access the data, the AWS CLI tool can be used. CLI commands for S3 is available there, too.
